A collection of information and links about the Canon EOS 40D DSLR

The 40D was announced in August 2007, finally being discontinued in June 2009.

Now widely available used, the 40D and 50D are a good basic cameras if you want to concentrate on photography and are not interested in video.

The pentaprism viewfinders are noticeably better than the more basic XXXD or 'Rebel' range.

New Firmware 1.1.1

Fixes a malfunction that in rare occurrence causes a low battery indication to be displayed when using the EF 85mm F1.2L II USM lens. Depending on the battery check timing of the camera, the battery level displayed on the camera's LCD data panel may shows Battery will be exhausted soon or Battery must be recharged, even though the battery capacity is sufficient.

Fixes a malfunction that in rare occurrence causes an Err 06 Self Cleaning Sensor malfunction to appear on the camera's LCD monitor and LCD data panel, even when the Self Cleaning Sensor Unit is operating normally. This message may appear depending on the timing of when the camera is switch to the ON position.

Fixes a malfunction that prevents correct colors from being printed when direct printing. RAW images captured using the camera's custom Picture Styles (Emerald, etc.), which have been downloaded from Canon's Web site and registered under User Def. 2 or User Def. 3.

Modifies the level of subject brightness that causes the AF-assist beam to fire when using an external Speedlite.

Enables an external flash connected to the camera's synchro terminal to fire even when the camera's built-in flash is popped up.

October 4th

Correction to yesterday's info... I'm told you use an additional program on a card to boot the camera from.

I was kindly sent this collection of info [Thanks]

3rd Do you have a spare 40D siting round?... i.e. one you don't mind potentially wrecking? If so there is some experimental software to enable video recording (after a fashion) - video of this on YT

September 1st Canon USA has a rebate program.... "Save $150 instantly when you buy the 40D + 70-300 IS"

August 26th 50D announced

21st As expected, there is a £60 rebate (75 Euro) on the 40D running for a month from today (to 21st Sept)

Details from Canon

19th We've heard of a rebate scheme being offered on the 40D, starting later this week - but only running for a month?

July 20th As US rebates end, I'm told the price on Amazon remains the same. Meanwhile UK prices hold at around £600.

I've seen renewed speculation that we are due a 50D for photokina, but while the XXXD cameras might move to a 1 year upgrade cycle, I can't see it happening for the XXD line.

June 28th In the US I'm also hearing of 40D price drops ($940 at B&H is similar to UK lowest), but if you buy from abroad then the rebates may not apply - check the details.

26th In the UK the price before rebate (£100) has dropped to £470 [camerapricebuster]

Updated - looks like it might have been a ploy to get sales, since the price has gone back up

20th From POTN
"Today Canon extended the rebate campaign on the 40d in Japan until August 3rd. About USD $100 cash back on 40d, about $200 cash back on 40d with ef-s 17-85mm."

May 11th The US rebate scheme will run from May 18th to July 19th.

It's an 'instant rebate' scheme, which will please a lot of people given the issues with past mail in rebates.

canon lens and camera rebate

Looks like the ideal chance to pick up that 28-90 you've been hankering for... :-)

April 27th Possible lens/camera rebates in the US? [Dealer comments DPR]

BUT note price rises before [details on 5D2 page]

9th 40D firmware update to V1.08 (Canon Japan version (en))

This includes fixes from V1.05 (20th November 2007)

There is also this update for the 30D (1.0.6) which we missed back in March

it includes 1.05 changes

1st I just had a flyer from Calumet in the UK with the 40D down to £519 after rebate (£709 - 17-55 kit). Well worth a quick shop around (a quick look suggested that it shouldn't be too difficult to get one for just under £500) I can't see it going much lower at the moment, with 450D sales on the up.

  • Several people have asked if anything new is on the cards? but unless Canon start introducing 'minor' feature updates, I'd not expect a 50D (or whatever) until next spring. It's well known that most cameras have additional functionality that could be used with updated firmware, but the precise mix you get in any model is usually the result of a series of battles between marketing and engineering :-) "yes, we could have 12800 ISO, but it would look cr*p" ;-)

March 23rd Lot's more indications of 40D price cuts around the world [DPR]

21st Quite noticeable price reductions for the 40D in the UK - now down to £600, and with £100 cashback too. Rather too soon for an update ??

February 15th Canon have released an update for Mac users of the EOS Utility software for 1D3, 1Ds3, and 40D. It fixes and issue with downloading images after using liveview.

New European rebate scheme to run from 1st March through to 30th June? (details on 5D2 page)

January 29th Since the 450D has contrast detect AF in liveview, why not in the 40D? Given the modular nature of code in their cameras, it should be a relatively easy addition (it may well be there already, but disabled)

  • Other camera manufacturers can add extra features (such as Olympus adding in body IS support for old lenses). Is the concept of doing a little something to make some of your owners happier in place at at Canon? (and yes I would like it for my 1Ds3 as well thanks! ;-)

2008 January 26th Although probably far too soon, some people have been discussing an update to the 40D. I've put what there is on the 50D rumours page

2007 November 20th Firmware update 1.0.5 is now available from Canon

The firmware update (Version 1.0.5) incorporates the following improvements and fixes.

15th Mac OSX 10.4.11 has been released and I'm told it now includes 40D support.

There have been no new releases of firmware as yet, so it looks as if v1.0.4 is not considered a user installable upgrade.

5th There are supposed problems with the raw files generated if you use the latest version of the 40D firmware V1.0.4

Although a 'fix' to allow Photoshop ACR to read files has been posted, a bigger problem that more people are having, is that no-one can find V1.0.4 to download. It's not on the main Canon EOS site and seems to have been installed either by Canon Service, or come with new cameras.

October 31st Several Canon software updates are available for download (details on 5D2 page) It specifically includes 40D support

30th I've just been sent a cautionary tale from someone buying from one of the 'cheaper' sites here in the UK.

It seems that a 40D that turned up from HiDigital was a 'Grey Import'. The camera came without the user's manual or European warranty, and with a US battery charger plus an adapter for UK sockets. To further complicate matters the display language was set to Chinese (remember... no manual)

  • Whilst I've also heard of people happily geting items from this vendor, just remember that sometimes things are cheap for a reason. I'm getting my 1Ds3 from a Canon Pro Dealer - I'd rather potentially pay a little more for an item that my livelihood depends on, than risk getting something a few quid cheaper, only to find i've no usable warranty. Caveat Emptor

19th It would seem that there is a rebate on the 40D in the US, you just have to buy a Canon printer at the same time.

EOS 40D/XT/XTi rebate form (pdf) with 9000/9500 printer
EOS 40D/XT/XTi rebate form (pdf) with MP610/970 printer

To need to purchase through an authorised dealer and no doubt jump through various other hoops as well - see the dealer list at Canon

For European versions see 23rd Sept, below. Quite a few people from the US I've heard from seem underwhelmed at best...

5th I'm told (thanks) that Hidigital in the UK are down to £675 - but with no mention of the cash-back

4th There's a thread over on POTN showing some examples of why you might want to look at mirror lock-up for some very fine detail shots with the 40D. I've now heard that this is the 'vibration' problem that some have had - it seems to be a result of poor damping of the mirror when it flips up on some cameras. Easy enough to test.

  • Personally I rarely ever use a tripod (other than at night and for interiors) with a 1Ds since the extra bulk of the camera coupled with steady hands, gives me shots as sharp as I want. However, the amount of shake shown in the examples would be a concern if I saw it in a camera - from what I've heard, this is not a common problem

3rd Although it seems 7dayshop are offering some pretty good looking deals (in the UK), I've just heard from someone given a right run-around, even after ordering an item supposedly 'in-stock' ... thoroughly shoddy service. Just be careful when looking for bargains

29th September Is there a 'vibration problem' with some 40Ds?

It's just I received a report of some 40Ds having a problem sometimes after pressing the shutter release. This came from Japan and appears to have lost quite a bit in translation, so if anyone has any additional info I'd welcome an email?

From the report I had it seems Canon replaced faulty items pretty quickly, but the whole report was sufficiently vague that I can't be sure what it's about?? ;-)

28th The 40D is now getting a £50 rebate in the UK - no doubt some dealers will cut back on some of the recent heavy discounting to reclaim some of their margins, so shop arround.

I was also told that the Dixons stores at Heathrow and Gatwick are doing a 'duty free' deal for the 40D with the kit with the 17-85 IS lens at £936

  • BTW I'm currently travelling in the US - so updates may be a little patchy for the next couple of weeks. I'm keeping a travel blog of sorts if anyone is curious ;-)

23rd Canon Europe rebate info is on the 5D2 page, including a 70 Euro rebate on the 40D from October 1st to the end of the year

22nd A new 40D review has been posted over at PhotographyBlog

18th - Back to 40D prices :-) I'm told that HiDigital in the UK are down to £711

17th After several interesting sets of correspondence over the week-end which converged on the same basic info, we've added updates to a lot of the various rumour pages (see the rumours index page for all of today's updates)

It seems that Canon is very happy about the initial dealer and customer reaction to the 40D, although somewhat surprised about D300 comparisons (D300 was thought to be more up against the 5D2)

Canon marketing know that ISO6400 (as a H2 option) and improved AF during liveview could be added in a firmware update. The 6400 option is supposed to give better results (with in-camera processing for JPEGs) than just underexposing by a stop at 3200. Given that this is eating into the feature set sketched out for the 50D, it's appearance will depend on how much pressure marketing exerts as a result of the increased competition in the market (this is covered on the 5D2/general rumours page)

16th As someone with a lifelong interest in Astronomy (I did it at University) I was greatful to be sent details of this review of using the 40D for Astrophotography (in French and English)

15th A couple of 40D reviews FYI

  • Writing camera reviews is something I'd hate to have to do regularly - I've just not got that picky careful attention to detail that you need to do good comparative ones :-) I enjoyed looking at the Ricoh GZ100, but that was a one off (until I get a 1Ds3 later this year ;-) It's very hard to keep your personal preferences and biases out of a review, so I always like to read several to look for common trends.

The £785 I mentioned from HiDigital back on the 30th has dropped to £745

14th Downwards go the prices...

In the UK Jessops have dropped to £786 and 7dayshop to £754 - now back to £769 with "free" Sandisk CF 2Gb Extreme III card. The price too from Park Cameras has also dropped several times over the last week - always remember to see what you can get when you phone up dealers!

13th - That 40D in the window ... now £799 (body only), whle I've noticed some of the better known UK mail order people going down to £779 (FYI I believe the wholesale price in the UK is around £700)

12th In one of our more precise reports I'm told of a 40D in the window of T4 in Swindon (UK) for £833 ;-)

11th The 40D seems pretty widely available now. and I've had several messages from people in the UK successfully getting a price match at large dealers. I've also had comments from the Netherlands about availability too, at fotokonijnenberg.nl and kameraexpress.nl

  • Thanks again for all the comments and news!

9th A while ago I built a view camera adapter for my 1Ds. I did wonder at the time how good it would be with smaller sensor cameras, that were never designed for manual focusing.

I've had a report (thanks) about how it was not terribly useful with a 350D or an S3...

However with a 40D and liveview it suddenly becomes easy to focus and all the benefits of extreme shifts and tilts become usable.

Metering seems pretty unphased by the movements too...

In Taiwan, the 40D arrived a few days ago (NT$ 38500 ~US$ 1167) and at the main Canon dealer they were giving away rather nice camera bags with a 40D (Thanks for info and pics)

7th I heard from someone in the US who just got their 40D - ordered on the day of the announcement. In the UK it seems that you can pick up a 40D for £800 at Ask, along Tottenham Court Rd in London.

Note too, the 40D WP link above - quite an interesting read

6th After all of yesterdays leaks, the Sony A700 is for real, and firmly aimed at a similar market to the 40D

I'm also told that Jessops in the UK have the 40D at £839 - all these people want you money, so it's always asking for a deal :-)

5th The 40D hits the shops in the UK - I heard of someone buying one at T4 in Swindon at lunchtime :-) In the US B&H advertise the 40D at last...

Meanwhile, that excellent RAW converter Bibble offers 40D support (and tethered shooting)

There are a whole load of Sony A700 leaks currently doing the rounds - more specs (D300 like) on the 5D2 page

4th More info on availability... Dabs in the UK ('3-4 days') at £849, while 7dayshop say £779 ('In stock'). In Germany fotoversand24 are shipping. In the US, Ritz are saying "shipping now", but that turns into "stock in 2-3 weeks" when you call ;-)

Park Cameras in the UK - tell me that they are expecting a delivery of 40Ds tomorrow (£859 - at most ;-). RGB (in the UK) are expecting cameras by next Monday, and another batch 2 weeks after that. The delay is apparently due to "Canon UK kitting out the boxes with manuals etc." Even Jessops are claiming to have them... ;-)

There is also a 'hands on' 40D review at LL

3rd At last, Amazon in the UK are saying 19th September (at full MRP mind you), and I hear that J&R in NYC are shipping them. Play.com looks good for UK prices, but not until the end of the month.

There appears to be some vagueness about pricing in the UK, and many dealers are still not giving a definite price. Could Canon be moving on pricing, given the recent Nikon announcements ;-)

  • Thanks to everyone sending in info ... and don't forget, if you find a really cheap camera, then do look for the catch ;-)

2nd I heard of someone getting a 40D at Best Buy (US) this morning, and managing to use a 12% 'Reward Zone' discount voucher (since the staff rarely read the fine print ;-) $1319 for the kit with the 28-135 lens. It seems that stocks are limited...

The introductory review by Roland Lim I mentioned the other day has been much expanded, including some very useful comparisons with the 20D.

1st A new user (thanks Jim) of the 40D has kindly scanned the manual and made it available as a PDF

August 31st The 40D is being shipped in Germany - a dealer (in Munich) with over 60 on order is getting the lot tomorrow - or so Canon says ;-) I've also just heard of one being shipped from OneCall in Spokane - looks as if there will be plenty in people's hands by later next week.

As real reports of use come in I'll add any particularly good reviews or information I find to this page.

30th Lots of sample images at a Japanese site. The various translators seem to do a good job on the technical bits you might want to know about, but you can work out a lot from the numbers posted.

In the UK prices seem to be falling with several dipping below £800. Once again check the fine print if warranties are important to you, and don't forget the 'import duty and taxes not included' fine print when you see a £673 price tag on somewhere like DigitalRev. I've also heard that one well known retailer in the UK was prepared to do a price match with the £785 from HiDigital.

In the UK it seems Sept 15th is a popular date being given for shipment of the 40D

Meanwhile in the US it seems Amazon's dropped back to 'pre-order' and 'will arrive soon' ...

29th I hear from California (thanks) that there are various kit options being pushed with the 40D, all at similar prices. This includes the 17-85 IS. The official prices are supposedly still not known by some dealers...

Amazon (.com in the US) has moved their delivery date up to the 30th of August and has dropped the "this is a high-demand item" comment. (Thanks to everyone who pointed this one out)

  • Is 40D demand not at the levels expected? ;-) I've heard from several dealers that many of their orders were 10D and 20D owners who hadn't seen the 30D as a real upgrade for their use. Are new users looking to the D300? As someone with a not inconsiderable investment in Canon glass there was no reasonable likelihood of me considering Nikon at this time. However some new entrants to the market now have a choice, which is never a bad thing. My only concern is the torrent of clueless drivel I'm seeing on some of the 'discussion' forums. I take much of what I've read about the relative merits of different cameras and features, with an even bigger pinch of salt than I do with my own rumour pages :-) ;-)

Some cameras are reaching people now, and a few have posted their thoughts. I thought Roland's initial comments gave a good impression about how a 20D user would feel moving to the 40D.

  • Not enough techy detail for some perhaps ;-) However I'm sure it won't take long for some detailed 'Anorak' level reviews to appear :-)

28th An interesting report on a Japanese site (Google translation - actually of use!) suggests that Canon's claims of better noise and detail performance at high ISO's is not just marketing puff ;-)

There's also this translation of some resolution tests.

We're also hearing that UK prices are moving somewhat. Whilst the official SRP is ~£900. We're told that it's been found at Bestcamera for £849. Note that the 'official' price still seems somewhat fluid, so it's worth shopping around, although that may not get you one of the first cameras ;-)

Updated - we're now told that 'RGB Labs' in the UK is listing the camera at £770

  • Just remember when shopping around, to compare like with like and make sure that you are getting what you think you are getting (full warranty, all the standard extras etc) Things that look too good to be true often are... ;-)

26th lots of sample jpeg 40D images at DPR

23rd Nikon announce the D300 and D3 - giving Canon something to seriously think about...

22nd Some sample 40D images

21st I've had a few mails asking about the worldwide pricing policies on this camera. The UK (body only) price is typically about £900, which includes VAT (tax) at 17.5%, so you have a base price of £766. In the US I see Amazon advertising at $1300 - which gives a conversion rate of 1.69 I just checked and today's tourist rate is ~$1.87 to the pound, giving an equivalent UK price of £695. However that price is before any taxes and only gets you a US warranty - something I'd suggest people look at very carefully before heading of on a cheap flight to New York in a few months.

The new WiFi grip has real Ethernet and USB2 connectors too. With it's improved sensor and liveview the 40D makes it much easier to use as a studio camera. Having used an 11MP 1Ds for some time for product photography, the image quality for the 40D should be more than adequate for a lot of work.

The full range of EOS 40D kit is shown in the 'system map' to the right. (Click on the image to enlarge)

In Germany Canon are saying October for availability, while in the US Canon is saying September (but see the press release below ).

There was the Best Buy 'leak' (archives) that suggested the second of September. In Japan I've heard reports of someone intending to buy one on the 31st August. Meanwhile B&H in the US are aparently not accepting 'pre-orders' until they get delivery info from Canon (DPR thread)

40D kit contents20th Thanks to everyone sending updates on this

Canon US now have their launch info up on their site.

Here's some comments in Dutch, Danish and comments on DPR

40D blurb from Canon USA (more details)

  • Fastest in Class 6.5 FPS Shooting Speed, New Autofocus Sensor and Newly Enhanced 10.1 Megapixel CMOS Imaging Sensor Combine to Boost the EOS 40D's Appeal While Maintaining its Accessible Mid-Market Pricing
  • LAKE SUCCESS, N.Y., August 20, 2007 – Following months of intense anticipation by Digital SLR enthusiastsworldwide, the EOS 40D DIGITAL SLR Camera from Canon U.S.A., Inc. is scheduled to begin sailing into stores in early September. Building on the success of Canon's perennially popular "prosumer" EOS 20D and 30D models, the EOS 40D advances the state-of-the-art for mid-range Digital SLR cameras, making it a natural first choice for advanced amateur photographers and entry-level professionals, and an ideal second body for more established photo pros. Indeed, given the level of feature upgrades and improvements, technological wizardry and user-requested creative controls, the Canon EOS 40D SLR's "prosumer" appellation may refer more to its accessible price point than to the exceptional quality, clarity and resolution of the images it creates. connectivity options
  • From the camera's newly enhanced, 10.1-megapixel CMOS imaging sensor (designed and manufactured by Canon) and its proprietary and super-efficient DIGIC III image processor, to its completely redesigned autofocus sensor and fast, 6.5 frame-per-second (fps) continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images), the EOS 40D SLR puts the fun in functionality and makes serious photo business a positive pleasure.
  • Indeed, at 6.5 fps, no Digital SLR in the EOS 40D mid-range class and price category has so high a continuous shooting capability1, making it ideal for shooting – and actually capturing – speed-sensitive outdoor and wild-nature shots as well as a wide variety of action and sports scenes. The speed of the EOS 40D SLR comes from Canon's balanced combination of its latest processor, DIGIC III, DDR SDRAM high-speed memory, four-channel-per-line sensor readout, and two separate motors for shutter and mirror operation.
  • "This newest member of Canon's Digital SLR family takes mid-range Digital SLRs to exciting new heights with enhanced resolution and image quality, faster shooting and processing speeds and better overall functionality than ever before," stated Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A."The EOS 40D Digital SLR Camera incorporates many Canon innovations and advancements that differentiate our products from the competition, while respecting and reinforcing our long-standing traditions of providing superior value and innovative imaging technology."
  • Display's the Thing
    The most easily visible upgrade on the EOS 40D Digital SLR is the camera's larger three-inch LCD screen (compared with the EOS 30D's 2.5-inch monitor). Still, size is only the beginning of the difference between these two cameras' displays. In order to increase viewing ease in outdoor conditions such as bright sunlight, Canon raised the40d back view brightness level of the EOS 40D camera's 230,000-pixel LCD screen, broadened the colour gamut and narrowed the viewing angle from 170 degrees to a still wide 140-degree perspective in all directions. An added advantage of the larger-sized display is the ability to use a larger font size for text, making it easier to read setting and menu options on the screen. The camera's menu is organized in the same tabbed format as the EOS-1D Mark III Digital SLR.
  • Canon extends its "ease-of-reading" policy to the EOS 40D SLR's viewfinder as well. The upgraded viewfinder increases optical magnification from 0.90x to 0.95x, expands the viewing angle from 251 degrees to 264 degrees and raises the eye point from 20mm to 22mm.
  • Enhanced Durability
    Recognizing the often rigorous shooting conditions encountered by professional and advanced amateur photographers, Canon design engineers made the EOS 40D SLR's magnesium alloy exterior even more ruggedly dependable than its predecessors with upgraded dust and weather resistant construction, particularly around the camera's connection ports, battery compartment and single-slot compact flash memory card door. Should the user inadvertently open the compact flash card door while the camera is writing to the card, a warning will pop up on the LCD screen and an open door "alarm" will sound, but the image(s) will continue writing to the memory card without interruption. The EOS 40D SLR also retains many of the outstanding features of the EOS 30D model, such as its fast 0.15-second initial start-up, its extremely durable shutter (rated up to 100,000 cycles), its top shutter speed of 1/8000 sec and 1/250 maximum X-sync flash shutter speed setting.
  • Improved Image Quality
    Although it is based on the image sensor used in the EOS Digital Rebel XTi, the EOS 40D Digital SLR's 10.1-megapixel CMOS APS-C size image sensor has been significantly improved thanks to the use of larger microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. The EOS 40D retains the model 30D camera's 1.6x focal length conversion factor (compared to full-frame digital image sensors or 35mm film) and is compatible with the full line-up of Canon EF lenses as well as the Company's expanding selection of high-quality, affordable EF-S lenses created specifically for Canon Digital SLRs with APS-C size image sensors. eos 40d front side view
  • Adding to the improved virtuosity of the images captured by the EOS 40D SLR is the camera's 14-bit Analog-to-Digital (A/D) conversion process. Able to recognize 16,384 colours per channel (four times the number of colours recognized by the EOS 30D SLR's 12-bit conversion capability), the EOS 40D camera is able to produce images with finer and more accurate gradations of tones and colours. The EOS 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the EOS-1D Mark III Professional Digital SLR.
  • DIGIC III
    DIGIC III is the latest generation of Canon's proprietary image processing engine. DIGIC III technology ensures that the fine details and natural colours of the images are optimally recorded and, as an added bonus, is also responsible for the EOS 40D SLR's high-speed performance, faster signal processing and even its efficient energy consumption.
  • sRAW
    In addition to retaining the RAW image capture capabilities of its predecessors, the EOS 40D SLR now offers a more manageable "sRAW" recording format. In sRAW mode, the number of pixels is reduced to one-fourth that of a standard RAW image and the file size is cut in half, while retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images.
  • Improved Autofocus and Exposure Control
    While the EOS 40D SLR maintains the nine-point wide area AF coverage first introduced on the EOS 20D camera, Canon has made significant improvements to its speed, precision and functionality, minimizing subject recognition problems in the process. The EOS 40D camera's completely redesigned nine-point AF sensor provides cross-type AF measurement at all nine focusing points for maximum apertures up to f/5.6, and for the first time in any EOS camera, the central AF point offers enhanced precision for both vertical and horizontal subject contrast when using EF or EF-S lenses featuring maximum apertures of f/2.8 or faster. AF calculation speed with the EOS 40D camera is 30 percent faster than the EOS 30D model.
  • The Canon EOS 40D Digital SLR retains the same 35-zone metering sensor as its predecessor. Available patterns include Evaluative metering, which is linked to all AF points and is set automatically in the Basic Zone modes, centreweighted average metering, Partial metering and Spot metering, covering approximately 9 percent or 3.8 percent of the viewfinder at centre, respectively. The camera's E-TTL II autoflash and 12 exposure control modes (11 AE modes plus manual) are also unchanged from the EOS 30D SLR model. However, as a result of consumer input, Canon has added three Custom exposure modes. As an added convenience, particularly for wireless flash operations, users can adjust the flash settings of the Canon Speedlite 580EX II directly from the camera.
  • The Canon EOS 40D camera offers ISO speeds from ISO 100 to ISO 1600 in 1/3-stop increments. Users can also opt for a high-speed setting of ISO 3200. For the first time in any EOS camera, the 40D model offers Auto ISO capability in Creative Zone exposure modes. This valuable new feature adjusts the ISO speed to the optimal setting based on low light or shaky shooting conditions. Additionally, the EOS 40D provides full-time display of the active ISO speed setting, both in the viewfinder as well as on the top LCD data panel.
  • The Canon EOS 40D Digital SLR is also the first camera in its class to offer two interchangeable focusing screens in addition to the standard precision matte screen. Users can opt for a grid-type focus screen that makes it easier to verify horizontal or vertical alignment while determining image composition, as well as the Super-Precision Matte focusing screen that makes it easier to grasp the "sweet spot" of manual focusing when using a lens with a maximum aperture of f/2.8 or faster.
  • Enhanced Live View
    Previously the province of the EOS-1D Mark III DSLR (one of Canon's top-tier professional cameras), the Live View function now gives EOS 40D camera users an expanded and exceedingly convenient and comfortable set of shooting options. By permitting the framing and capturing of subjects using the camera's LCD screen instead of the viewfinder, the shooter gains a 100 percent field view to more easily achieve the desired composition. A new Custom Function on the EOS 40D allows autofocus during Live View by pressing the camera's AF-ON button. At that point, the reflex mirror goes down and AF is carried out in the normal way. Letting go of the AF-ON button resumes Live View functions. Also, in the Live View shooting mode the user can magnify the image by five or ten times in order to ensure that the shot is optimally focused. Live View is at its best during tripod shooting – particularly for close-up photography where precise focusing is imperative. As a side benefit, the Live View shooting mode helps to reduce vibration by lifting the reflex mirror out of the optical path well in advance of the exposure, improving image quality at slow shutter speeds. A new electronic 1st-curtain shutter function in Live View mode reduces release time lag and operational noise even further to avoid spooking wildlife or disturbing people nearby with unwanted camera sounds. Additionally, as the release time lag is miniscule, even instantaneous movements like a bird taking flight can be readily captured.
  • EOS Integrated Cleaning System
    First introduced on the EOS Digital Rebel XTi camera, the EOS Integrated Cleaning System is a prime example of trickle-up technology and is now becoming a standard feature on all new EOS Digital SLRs. The camera's Self-Cleaning Sensor Unit uses ultrasonic vibrations to literally shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. Users also have the option of engaging the "clean now" function at will or bypassing it altogether. Additionally, the EOS 40D SLR's manual sensor cleaning function raises the mirror and allows users to clean dust that has stuck to the low-pass filter. Dust that has been shaken or blown loose is then trapped by adhesive at the base of the sensor unit housing, preventing the problematic particles from reattaching themselves to the filter when the camera moves. The second part of the cleaning system is a software solution that maps the location of any spots that may remain on the sensor. The mapped information is saved as Dust Delete Data and attached to the image file. Subsequently, the offending dust information is subtracted from the final image during post processing with a compatible personal computer, using the supplied Digital Photo Professional software.
  • Improved Software
    Among the most valuable features of the Canon EOS 40D Digital SLR is its compatibility with Canon's Picture Style Editor (PSE) 1.0 software. With PSE, shooters can actually design the look of their photographs by inputting their own preferred style, colour and tone curves. The EOS 40D Digital SLR also ships with the latest versions of Canon's powerful software applications, including Digital Photo Professional 3.1 and EOS Utility 2.1, which now support the camera's Remote Live View and Dust Delete Data functions, as well as incorporating a broad range of additional improvements designed to improve image quality and speed up workflow. Also included are ZoomBrowser EX 5.8 and ImageBrowser 5.8 for easy browsing, viewing, printing and archiving with compatible computer operating systems, including Microsoft Windows Vista and Windows XP, as well as Mac OS X.
  • Accessories
    New system accessories for the EOS 40D SLR include the redesigned high-capacity Battery Grip BG-E2N, which facilitates high-volume shooting and easier vertical shooting.
  • Compatible with up to two BP-511A battery packs or a set of six AA-size batteries, the battery grip approximately doubles the number of shots that can be taken, compared with the battery power of the EOS 40D SLR alone.
  • The BG-E2N grip features new sealing material around the battery compartment to better resist water and dust. The new model replaces the original BG-E2 grip and is compatible with the EOS 20D, 30D and 40D models.
  • WFT-E3A
    Designed exclusively for the EOS 40D SLR, the new Wireless File Transmitter WFT-E3A*/** permits wireless transfer and back-up, as well as remote control of the camera in Live View mode. It can also be connected to various GPS receivers or Hi-Speed USB 2.0 external storage devices such as convenient flash drives or high-capacity hard drives with much larger storage capacity than the memory cards in the camera for instant back-up as images are captured.
  • Compact and affordable, the WFT-E3A wireless transmitter also doubles as a vertical grip and requires its own BP-511A battery pack in addition to the battery installed in the camera body.
  • EF-S 18-55mm f/3.5-5.6 IS Lens
  • Developed in response to consumer demand for a high-quality yet affordable optically image stabilized lens, the Canon EF-S 18-55mm f/3.5-5.6 IS standard zoom lens adds a phenomenally flexible lens to the EOS 40D SLR shooter's imaging arsenal. While it features the wide-angle to mid-range zoom flexibility of its non-IS predecessor, this new EF-S 18-55mm f/3.5-5.6 IS lens offers the significant advantage of a true lens-shift image stabilization system that yields up to a full four stops of image-shake correction.
  • The higher performance provided by Canon's lens shift IS system (compared with the in-camera sensor shift type offered in some competitive SLRs) includes the ability to optimize the lens performance for specific shooting situations such as low-light, long-zoom or movement while shooting (or virtually any combination of the three). What's more, the shooter can see the image stabilization effect in the viewfinder. As the image already appears steady, more accurate framing and composition is possible, the AF point can be placed more precisely, and the photographer can concentrate on the optimal shot more comfortably.
  • Compact and lightweight, the optional EF-S 18-55mm f/3.5-5.6 IS zoom lens is manufactured by Canon specifically for the EOS 40D SLR and any other EOS SLR that takes EF-S lenses including the EOS 30D, EOS 20D, EOS 20Da, EOS Digital Rebel XTi, EOS Digital Rebel XT and the original EOS Digital Rebel camera. An ideal complement to the EOS 40D SLR, the EF-S 18-55mm f/3.5-5.6 IS lens is scheduled to be in stores in October at an estimated selling price of $199.99.
  • The Canon EOS 40D Digital SLR is scheduled for early September delivery and will be sold in a body-only configuration at an estimated selling price of $1,299.00i. It will additionally be offered in a kit version with Canon's EF 28-135mm f/3.5-5.6 IS USM zoom lens at an estimated selling price of $1,499.00i.

Product Description
From Canon
Building on the success of Canon's perennially popular "prosumer" EOS 20D and 30D models, the EOS 40D advances the state-of-the-art for mid-range digital SLR cameras, making it a natural first choice for advanced amateur photographers and entry-level professionals, and an ideal second body for more established photo pros. Indeed, given the level of feature upgrades and improvements, technological wizardry, and user-requested creative controls, the Canon EOS 40D SLR's "prosumer" appellation may refer more to its accessible price point than to the exceptional quality, clarity, and resolution of the images it creates.

From the camera's newly enhanced, 10.1-megapixel CMOS imaging sensor (designed and manufactured by Canon) and its proprietary and super-efficient DIGIC III image processor, to its completely redesigned autofocus sensor and fast, 6.5 frame-per-second (fps) continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images), the EOS 40D SLR puts the fun in functionality and makes serious photo business a positive pleasure.

Indeed, at 6.5 fps, no digital SLR in the EOS 40D mid-range class and price category has so high a continuous shooting capability, making it ideal for shooting--and actually capturing--speed-sensitive outdoor and wild-nature shots as well as a wide variety of action and sports scenes. The speed of the EOS 40D SLR comes from Canon's balanced combination of its latest processor, DIGIC IIII, DDR SDRAM high-speed memory, four-channel-per-line sensor readout, and two separate motors for shutter and mirror operation.

Display's the Thing
The most easily visible upgrade on the EOS 40D Digital SLR is the camera's larger 3.0-inch LCD screen (compared with the EOS 30D's 2.5-inch monitor). Still, size is only the beginning of the difference between these two cameras' displays. In order to increase viewing ease in outdoor conditions such as bright sunlight, Canon raised the brightness level of the EOS 40D camera's 230,000-pixel LCD screen, broadened the colour gamut, and narrowed the viewing angle from 170 degrees to a still wide 140-degree perspective in all directions. An added advantage of the larger-sized display is the ability to use a larger font size for text, making it easier to read setting and menu options on the screen. The camera's menu is organized in the same tabbed format as the EOS-1D Mark III Digital SLR.
Canon extends its "ease-of-reading" policy to the EOS 40D SLR's viewfinder as well. The upgraded viewfinder increases optical magnification from 0.90x to 0.95x, expands the viewing angle from 251 degrees to 264 degrees and raises the eye point from 20mm to 22mm.

Enhanced Durability
Recognizing the often rigorous shooting conditions encountered by professional and advanced amateur photographers, Canon design engineers made the EOS 40D SLR's magnesium alloy exterior even more ruggedly dependable than its predecessors with upgraded dust- and weather-resistant construction, particularly around the camera's connection ports, battery compartment, and single-slot compact flash (CF) memory card door. Should the user inadvertently open the compact flash card door while the camera is writing to the card, a warning will pop up on the LCD screen and an open door "alarm" will sound, but the image(s) will continue writing to the memory card without interruption. The EOS 40D SLR also retains many of the outstanding features of the EOS 30D model, such as its fast 0.15-second initial start-up, its extremely durable shutter (rated up to 100,000 cycles), its top shutter speed of 1/8000 second, and 1/250 maximum X-sync flash shutter speed setting.

Improved Image Quality
Although it is based on the image sensor used in the EOS Digital Rebel XTi, the EOS 40D Digital SLR's 10.1-megapixel CMOS APS-C size image sensor has been significantly improved thanks to the use of larger microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. The EOS 40D retains the model 30D camera's 1.6x focal length conversion factor (compared to full-frame digital image sensors or 35mm film) and is compatible with the full line-up of Canon EF lenses as well as the Company's expanding selection of high-quality, affordable EF-S lenses created specifically for Canon digital SLRs with APS-C size image sensors.
Adding to the improved virtuosity of the images captured by the EOS 40D SLR is the camera's 14-bit Analog-to-Digital (A/D) conversion process. Able to recognize 16,384 colours per channel (four times the number of colours recognized by the EOS 30D SLR's 12-bit conversion capability), the EOS 40D camera is able to produce images with finer and more accurate gradations of tones and colours. The EOS 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the EOS-1D Mark III Professional Digital SLR.

DIGIC III
DIGIC III is the latest generation of Canon's proprietary image processing engine. DIGIC III technology ensures that the fine details and natural colours of the images are optimally recorded and, as an added bonus, is also responsible for the EOS 40D SLR's high-speed performance, faster signal processing, and even its efficient energy consumption.

sRAW
In addition to retaining the RAW image capture capabilities of its predecessors, the EOS 40D SLR now offers a more manageable "sRAW" recording format. In sRAW mode, the number of pixels is reduced to one-fourth that of a standard RAW image and the file size is cut in half, while retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images.
