2008 July
10th After all the 1D3 AF issues, Rob Galbraith is promising an update on testing (1Ds3 and 1D3) later this month.
May 2nd Note that there appears to be a slight glitch on the warranty extension web site, in that it asks for your date of birth rather than purchase date - this results in your warranty being extended to your second birthday.
1st Canon have announced a warranty extension programme in Europe for the 1Ds3 and 1D3. Warranty will now run for two years from the purchase date (for cameras purchased up until the end of this year)
Registration online only...
An interesting set of tests of the new firmware (birds in flight) on the UKBirdphotographers forum (see 2nd and 3rd pages). Lots of images and the update gets a thumbs up.
April 30th New firmware
EOS-1D Mark III
http://web.canon.jp/imaging/eos1dm3/firmware.html
This firmware update (Version 1.2.3) incorporates the following improvements.
There is new firmware for the 1Ds3 as well.
Image below is from PDF describing changes

There is an update on RG with some more useful comments
April 29th Firmware update tomorrow? This from DPR a dealer letter from Canon
Is this sorted at last? here is a Google translation of an article suggesting that it is V1.2.3 and that it has already been seen. It also seems that joystick control of the focus point is back.
27th Possible lens and camera rebates in the US? [DPR] BUT note price rises before [details on 5D2 page]
25th Is there news at last of a possible 'final' firmware fix?
There is this Spanish item which (I believe) hints at new flash adjustments, new personal function settings, and Autofocus in a firmware update on the 30th.
Another more vague hint at WHX (6th post). This ties in with reports I've heard from 1D3 owners who have had some cryptic comments at recent shows from Canon reps. [Thanks to all who've sent in info on this]
March 5th Canon have made an update to their 1D information. Make of it what you will...
In a comment at RG, he wonders if the statement is just to buy more time before the next 'fix'?
1st I've been checking the AF accuracy of my 1Ds 3 and setting the AF microadjustment for a couple of my lenses that needed it. I was using a test image I was recently sent and have put together some notes on AF Microadjustment showing how it works (with a version of the test image). This procedure would be exactly the same with the 1D Mk3.
February 27th There's a more detailed update on the 'AF in blue' story mentioned below (21st) at RG
The blue colour... "cited as a significant factor in the autofocus problems EOS-1D Mark III shooters were encountering, but the photographer we spoke with said that the camera's autofocus performance changed with the quality of the light primarily, and that it was far from certain that the blue hues of the playing area were contributing to the camera's autofocus troubles there."
Meanwhile "Canon USA Technical Advisor Chuck Westfall says only that officially, the company is 'continuing to investigate possible improvements to EOS-1D Mark III autofocus, and if anything is developed it will be announced as soon as possible.'"
"a Canon internal email" [suggests] "that a fix is coming in the form of a firmware update that's intended to improve EOS-1D Mark III autofocus in specific types of light."
Obviously the 1D AF saga is not over yet! (I've still not noticed problems with my 1Ds3, but then again I don't do sports work)
26th Will the next firmware update finally add contrast detect AF to cameras with liveview. It would be nice if Canon broke their usual habits and added additional functionality to an existing model... [CR]
21st At last, a real true rumour (thanks!) - there's a report at ATP of a conversation overheard at a PGA golf tournament.
So there you have it... ;-)
Another AF related issue for the 1D3? According to a German site, problems were found with AF performance in scenes with a lot of blue in them. This was at the Australian Open in Melbourne recently. This was (not unsurprisingly ;-) investigated as a matter of urgency by Canon Japan, and Canon Germany have acknowledged that the problem is known and a firmware fix is the solution. [Google translation]
For the existing 1D3 fix, there is some more concrete info about the nature of the fix at POTN
16th Canon Europe are having another round of rebates (5D/40D/400D and lenses) it starts on March 1st and runs to the end of June - details on the 5D2 page.
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.
13th Canon have still not publically announced anything new to do with the AF issues. In fact, callers to some offices are being met with complete denials that there is a new fix...
The Canon 'Optimising AF' document [PDF] has been round a while, but we were just sent a link (thanks) to a German translation [PDF]
7th No 'Final Fix' yet? I've just heard from someone (thanks!) who had an interesting chat with an agency photographer. It seems that they are holding back from buying any more 1D3 (blue dot or not) until April the first when the 'fix' will be available.
6th Is there to be a 1Ds3 'recall'?? (1Ds3 page)
Meanwhile at one of Canon's US repair centres, there is no -official- notice of additional repairs... see this FM thread for more.
There's an interview with Chuck Westfall at CNET, which includes some AF related info:
"- Do you think you've resolved the 1D Mark III autofocus issue?
The hardware fix and firmware update has effectively brought the camera within the design specifications. Under the vast majority of study conditions, the camera is functioning exactly the way we expected it to."
5th No news yet from Canon about the 'final fix'
3rd Is there another fix for the 1Ds3? Certainly some people who've compared it to the old 1D2N have observed that it's not always as good.
Well there is a new update at RG, linked with the following:
Do read the article for the background, but I noted that:
January 30th A trade in offer when the 1D3 is superceded? (see 1D4 page)
29th I'm continuing to see some reports of lengthy delays in fixes to the camera, but most are round the week mark.
Obviously some people are still not happy, but see this FM thread for one happy user ;-)
10th I've had several messages today concerning Canon fixing the 1D3 in the UK.
It seems that Canon now have the OK from Canon Japan to extend the warranty for a year from when the 'fix' is applied.
Turnaround is currently only a few days, so with the warranty extension it might be worth delaying getting your 1D3 fixed if you are not experiencing any problems with it.

9th I've seen several comments about a downwards movement of 1D3 prices of late, only a few hundred dollars or so at the moment.
While a lot of people are happy with their repaired 1D3, there are still some experiencing difficulties - certainly nowhere near the level before the 'fix' was announced. For more views see this lengthy FM thread.
2007 December 27th I've just heard from a non CPS member in the UK, who has just had their 1D3 taken away ("about a week"). It seems that they also just happened to have a call from someone doing a customer satisfaction survey for Canon. Needless to say they were not entirely complimentary ;-)
[timeline - 4/12 Phone Canon, no estimate of times, 20/12 Canon call to arrange pick up, 27/12 camera goes away]
However I've also heard from another person who pushed Canon a bit (by phoning their Elstree repair centre directly) after an initial 'end of January' estimate and got their camera moved up the queue and after 4 days away it returned fixed, and with a 2GB card thrown in...
25th The CI story rumbles on in the forums (but probably hasn't made it too big since a lot of it is in French :-) Just one of those stories that reminds me that sometimes, when bad PR starts for a big company, it often takes on a bit of a life of its own...
Anyway, Happy Christmas (or Happy Holidays as for some reason, it gets called in the US ;-) to anyone visiting today! If you wonder why I've not got anything better to do today, well I'm in Ipswich, currently waiting for my Mum to cook the Christmas lunch, and it's that sort of quiet time you sit around waiting for the festivities to get moving.
21st In a fit of pique, it would seem that Canon France decided to pull all their advertising from the French magazine Chasseur d'Images... [original article in French] Unusually, the magazine which is quite popular in France, has decided to call Canon's bluff on this one.
"Canon France's general manager seems to be very hot tempered because he suddenly withdrew all advertisements in a magazine which dared to publish less than laudative comments on the focussing performance of the Canon EOS-1Ds Mark III." [25th - Correction - it should have been the 1D Mk3 ]
Since the French site doesn't seem to work with Google's translation service, here's what it makes of the content:
Elsewhere, there are comments coming in about repairs around the world, and the majority of tests I've seen suggests that it makes a real and positive difference (and I still have no issues whatsoever with my 1Ds Mk3 :-)
19th Some UK repair info from a number of 1D3 users on DPR (and another mention of a free 2GB card)
17th It seems that Canon in the UK are asking 1D3 users for their views when discussing 1D3 repairs... An FM post where the writer was 'rewarded' for sticking with Canon :-)
16th I had an interesting mail from Australia (thanks) covering how a 1D3 was fixed ... from a call from Canon on the 11th, with the camera air-freighted from Adelaide to Sydney, to the return of the fixed camera on the 14th. From lacklustre AF performance to what looks pretty good. So it seems that the fix doesn't need to take long (I've also heard of it bing done 'while you wait' at one Canon centre.
13th The fallout from the RG article rumbles on with more discussions as to when Canon will bring out a new camera. They only waited a year or so to bring out the 1D2N...
I was also sent (thanks) a link to someone's own 1D3 test on UKNP which mirrors some of my own (quick) tests with my 1Ds3
Canon have posted a PDF about getting the best out of the 1D3 and 1Ds3 - well worth reading.
10th The long awaited RG article about the 1D3 AF is finally published, and as expected says that the AF in fixed 1D3 cameras with the 1.1.3 firmware is a great improvement. However there are still some caveats where RG still says that sometimes the 1D2N works better - particularly in bright sunlight.
After all the delays - Canon has not given Rob an official response to his testing - that despite the article being held to wait for them. Make of that what you will, but while it may reflect corporate policy, it will not improve Canon's image amongst some people. Do read the whole article however, since Rob has been careful to include a lot of additional info and tips, and includes a lot of background info on how Canon (USA) have been involved and helped out.
There still appears to be cameras being sold in the 'needing a fix' range. I've heard from more people who've received new cameras that still will need sending away. There's a related thread on DPR.
In Australia the repairs are underway with one person commenting that:
"It only took them a few hours, I was told about 45 mins per camera. They were very good about it and helpful. I didn't have to keep following them up as I expected that I may have to do when I initially rang them."
8th Whoops... the RG article has been postponed until Monday ... rather than selectively quote bits, read what Rob has to say about it.
7th The state of repairs still seems to rather dependent on which Canon office you call in the world. In Austalia, a fixed camera came back with the comment:
"The part descriptions shows 'stopper, sub-mirror' (part No. CY4-0220-000) being replaced. The technician added that some adjustment were done to the focus mechanism, installed v1.1.3, cleaned sensor and tested the camera."[DPR]
It's now the 'week of the 3rd Dec' and the RG article on the 1D3 still hasn't appeared... as you'd expect, the conspiracy nuts are having a field day with this :-) UPDATE [RG]- it will be today or tomorrow ;-)
6th In a story that reflects very poorly on Dell and still none too well for Canon, we've heard from someone in the US who ordered a 1D3 from Dell back on the 7th of November. Delivered yesterday ... no blue dot on the box and yes it is in the range of serial numbers that need fixing.
What did Canon say? "... that they are taking a list and it could be at the outside FOUR MONTHS before all camera's are repaired. The actual repair time is about 10 days but if you at the end of the list, you are looking at possibly April to repair your camera"
Meanwhile Dell will refund the price (and shipping) but can't offer a replacement until maybe after Christmas, and then maybe not for the same price.
Shoddy work indeed from Dell... guess it's not only their computers I won't be buying...
4th In the UK I'm told (thanks) of someone calling Canon where after being asked if they were with CPS, were told that it would take 5 days once they were contacted by the service dept to send the camera in.
However, there was a comment on DPR claiming that Canon is actually giving replacement 1D3 for some large (and important ;-) customers like the wire services.
3rd The Canon page for 1D3 repair info has been updated Go to this URL https://self-service.Canon-europe.com/ and search for Case ID 72525
"Starting on 6 December 2007, Canon will begin offering free repairs for any affected EOS 1D-Mark III camera. In order to have your camera repaired, we kindly ask you to make a registration first at our Helpdesk. ... The Helpdesk will register each repair request in order for repairs to be handled as quickly as possible. After your registration the repair centre will call you back to make an appointment to repair your camera.
The Canon Helpdesk has been fully briefed to answer any questions you may have and to assist in resolving issues as soon as possible."
From someone who called in the UK:
"They are mentioning 'up to two weeks' turnaround for the cameras (though he did say that this was likely to be the upper limit.) "
Also, in the US at least, Canon is extending the warranty to one year from when your 1D3 was fixed [FM]
November 30th In a comment that should whip conspiracy theorists into a fervour, the RG article on 1D3 AF has been postponed
"The overdue next installment of our ongoing EOS-1D Mark III autofocus analysis article is going to be delayed for what should be the final time. For reasons that we'll be in a better position to explain once the update is published, we need to push its release into the week of December 3. Thanks for your patience."
I did a quick AF test on my 1Ds Mk3 this morning and it seemed to work fine. Note though that I've only ever used AI Servo mode a few times in the 4 years I've been using the 1Ds. I'm keeping comments and observations about my move from 1Ds to 1Ds3 on a page of their own :-)
28th Canon US have posted a new notice about the recall for servicing:
Canon U.S.A., Inc. will use the following procedure to accept EOS-1D Mark III cameras in need of an AF Mirror Adjustment.
Firmware 1.1.3 is released:
It includes the following improvements and fixes:
26th In Japan, Canon have started sending out emails to registered 1D3 users "advising that they were now taking applications to have cameras in the affected serial range fixed. The procedure is to either call a special hotline or go to one of the Canon repair centers." [DPR] In Australia "We are making preparations to offer repairs free of charge and will start accepting repairs from the 10th of December 2007 onwards." - major news agencies to get the fix first [DPR]
The new firmware will be Version 1.1.3 at least [Sportshooter]
25th A reason for the delay in RG's testing? There may be another firmware update available soon from Canon for the 1D3. It seems, via Chuck Westfall, that there is a 1D3 announcement due next week.
23rd In the UK it would seem that: "Canon UK will be doing the repair to CPS members bodies first, and that they were only waiting for tooling to arrive which would be as Canon have already stated at the end of November" [FM]
22nd The eagerly awaited AF report on RG has been delayed until next week...
20th For a positive 'blue dot' report (and some nice bird pics) see this FM thread.
18th A report on Naturescapes raises some concerns about the improvement in AF performance of a 'Blue Dot' 1D3. Whilst there are numerous reports of improved functionality as well, reports like this are not likely to inspire further confidence.
A lot of people (at Canon too I'll bet) will be waiting to hear the results of Rob Galbraith's testing, due out soon.
17th It seems there are some 'good' 1D3 cameras within the range of serial numbers announced by Canon.
More info at RG ... The 3450 cameras have serial numbers as low as 504234 and up to 546557. This puts them within the 501001 to 546561 range various Canon offices announced
16th There are some Nikon D3 sample images at RG... "We were given a preproduction D3 in late October, but in making the body available, Nikon USA stipulated that we not publish pictures from it. If we could, we'd show examples of how the D3 stacks up against Canon's EOS-1D Mark III at higher ISOs, and those examples would reveal that, while there are differences in the appearance of image graininess - Canon's grain is tighter and less visually objectionable - the D3 produces a higher-quality file overall at ISO 3200 and beyond. On the other hand, EOS-1D Mark III files - especially CR2s processed through Canon's Digital Photo Professional - are generally crisper and more detailed.More about this, and other comparisons, including how the D3's autofocus system stacks up against an EOS-1D Mark III with the recently-announced sub-mirror fix in place, will come when we have a production-level D3."
13th A short life for the 'unlucky' 1D3? info on the '1D4' page
12th People are getting repaired cameras, and new stock is appearing with the 'Blue Dot' mark. Reflecting a camera with the AF 'fix'
There is a lengthy thread on FM from people with new cameras, and others who for a variety of reasons are still not happy.
The picture at the right is from a larger image of a 1D3 box, showing just what the blue sticker looks like...
9th Testing of the new, fixed or 'blue spot' version of the 1D3 is underway at Rob Galbraith, although no definite timetable is in place, expect some comments next week...
7th If the Dell price is of interest, read this FM thread which has lots of stuff about coupons and various other marketing related obfuscation that if used correctly, might get you (in the US) a 1D3 for ~$3500
6th A 1D3 for $4000? I was sent a link to a Dell page which had a price of $4050 - that's just ~£2000 at current exchange rates.
New versions of the 1D3 are arriving in stores. A post on naturescapes mentions receiving a 1D Mark III with a serial number outside of the issue range. The boxes with 'fixed' AF have a blue sticker on them.
2nd A 1D3 for £1800 ... sounds too good to be true? I was asked about a site called dmxcity, supposedly in France, selling very cheap kit. Well, one of the first things I did is put 'dmxcity scam' into Google. All the results have big warnings, this is a complete and utter scam site. I'd say avoid -any- site that trys to get you to use a money transfer service such as e-gold. The whole area is full of crooks and scam merchants, this bunch even email people back if you ask for info.
It will probably change its name and re-appear to fool more people...
In the US you should also try the site resellerratings.com which is good at picking up the dodgy NYC photo 'shops'
Remember: Too good to be true ... usually means just that!
1st Canon USA announces its version of the recall notice...
There is some more info at RG including the observation from Chuck Westfall, that in the US:
Canon Europe follows Australia with an official announcement
Go to this URL https://self-service.Canon-europe.com/ and search for Case ID 72525
The title is
"Why do I experience inconsistent Auto Focus (AF) behaviour with my EOS-1D Mark III?"
The UK phone number is 00 800 22666 767 (UIFN-Universal International Free Number) or 08705 143 723 if you feel like paying for the call.
An official announcement from Canon in Australia
It not a minor thing for a Japanese company to use a phrase like "We offer our most sincere apologies to all who have been inconvenienced by this issue."
October 31st Several Canon software updates are available for download (details on 5D2 page)
30th According to AP, a Canon UK rep has confirmed the leaked letter with the confident 'I have seen the [internet] link to the letter. We think it is genuine... basically there will be an official announcement out on Wednesday regarding this.'
29th In the UK Calumet say that only certain serial numbers of 1D3 are affected. They should know those numbers later this week, and should be in a position to sell stock not on that list.
In another update I was told of Canon contacting people in the UK and letting them know that official notification would be on the Canon Europe site first (next week suggested as likely).
28th I've seen comments that quite a few US dealers are listing the 1D3 as on 'back order' - some still say they have stocks, but not everyone updates their web sites really quickly... I've not heard of anyone actually getting a 1D3 in the last few days though.
Some of what's mentioned in the PDF may be slightly suspect regarding UK consumer rights, regarding faulty/defective products. Note though that these are -consumer- rights, so if your business has purchased one, then you will not have the full weight of consumer protection legislation behind you.
27th We were just sent an interesting PDF... It purports to be from Lee Bonniface, Channel Director, Special Retail, Canon UK.
"Canon wishes to ensure a clear and concise message to the market ... "
It seems that Canon UK have withdrawn all unsold 1D3 cameras from UK dealers. A DPR post mentions this PDF sent out from Canon UK.
It says:
25 October, 2007
Re: EOS-1D Mark III Quality Issue
We would like to make you aware that we have concluded that there is a quality issue with some EOS-1D Mark III units in the market. The problem can be linked to the adjustment of the AF Sub Mirror, and we believe that this affects only a minority of units in the market at this time.
The phenomenon resulting from this problem (especially in high temperature) is that the optimal focus point is uncertain in AI servo mode, or that the tracking performance of AI Servo is not accurate.
Regarding the products that have been sold to consumers, we are currently preparing a resolution for this issue and will inform you of further detailed information and required steps through our official website at the end of October or the beginning of November. Canon will accept these units for repair, but we will not be offering an exchange or return.
In order to ensure that the customer experience is not damaged, and as a responsible company, Canon has decided to stop the shipment of all EOS-1D Mark III. We would therefore like to collect all unsold EOS-1D Mark III units from your stock. Please kindly contact Customer Administration on 01737 220841 to arrange a collection and a refund at your purchase price. We will inform you of the date that shipping will recommence as soon as it is confirmed...
As of today we are taking end-user inquiries with the above information through our Technical Help Desk on 08705 143 723. If you get an inquiry from an end-user, please advise them to contact this number until such time that the official website announcement has been published.
Canon wishes to ensure a clear and concise message to the market and we ask for your understanding, cooperation and support in this matter.
Please accept our apologies for any inconvenience resulting from this matter and please do not hesitate to contact your account manager with any questions that you may have.
Thank you for your continued cooperation and support.
So, at last some official word from Canon...
26th In the UK, expect an official Canon 1D3 announcement next week. I had a comment (thanks) from someone speaking to them. '...it has taken so long as there is a lot they [Canon] want get right (possible deluge of returns and the way to cope with this)'
It seems that UK prices are falling a bit more, with several people (such as Dabs) moving to £2500 (incl. VAT)
25th If you are using the WFT-E2/ E2A wireless transmitter, then there is a firmware update, Version 1.0.1 is available at Canon Japan
It addresses the following issue:
"The shutter cannot be released after the camera enters image transmission mode while network errors are occurring due to an unstable wireless or wired communication environment or connection.
With this fix, the images taken will be stored in the recording media (CF card or SD card) even if network errrors occur prior to or during image transmission."
23rd Still much confusion about the fix if this DPR story reflects the view from Canon UK... if anyone has had any more positive responses, do let us know :-)
There's still indication as to how to find out if your 1D3 is one with a problem (AFAIK)
22nd Still not much word from some parts of Canon about the AF fix (I'm told that Canon in the UK are now acknowledging it ;-). There's a bit more info on IR where we learn that "Canon made clear that the service program would be done at their expense, and any cameras returned for service would be fast-tracked through their repair organization."
20th The sub-mirror problem is 1D3 specific. From the latest RG info:
"Canon is planning to provide a simple way for EOS-1D Mark III shooters to identify if their camera was manufactured in production runs that included a sub-mirror assembly that is either adjusted differently or contains one or more different parts than a fixed sub-mirror assembly."
18th Many more reports saying that Canon is indeed going to 'fix' cameras. There doesn't appear to be a date or serial number range (publicly) available yet, so phone Canon for instructions about camera returns.
Lots more details on the 'fix' at RG
It is... "A hardware fix. Specifically, a component in the camera called the sub-mirror must be adjusted. The sub-mirror - also called the secondary mirror - is a tiny mirror behind the main mirror that passes light down to the autofocus module in the base of the mirror box. The adjustment procedure may include the swapping of one or more parts that make up the sub-mirror mechanism, though the sub-mirror component itself will not be replaced."
17th Do we have a 'fix' for the AF problem? A DPR poster says that Canon in the US have said that the fix (for affected cameras) is the replacement of a "Submirror assembly"
The (unnamed ;-) Canon rep said "they are to start collecting names of owners to contact, in addition to going off of existing registration data." It seems that Canon service now "have a statement they can give to 1d3 owners who call in about the focusing issue."
Several people have said that they have return info from Canon, so it would appear that if you have an AF problem then the best thing to do is ring Canon again. To reach the pro SLR team in the US, I see that it is to call "800 OK CANON and follow the prompts"
September 28th Still no news on when the latest firmware update will be available for download. Meanwhile I've heard from several people with genuine AF related problems, and the response they've had from Canon has not always been overly helpful.
Many of the frontline Canon techs don't seem to realise just how offensive even a polite version of 'read the manual' (RTFM) can be. Of course this could be all they are -allowed- to say in which case I can sympathise...
17th More thoughts on what's happening at Canon over the 1D3, from several different reports we received over the weekend (see rumours index page for all the different info)
There has been some significant embarrassment over the AF issues at Canon.
Canon have some sense that the issues were 'blown up' a bit through the internet
However there is an [internal] acknowledgement that it hasn’t been good for their reputation in the 1 series market.
There has been an unusually high number of returns of the 1D III, with some stores returning 1 in every 10 bodies.
Needless to say there has been a lot of hand wringing and angst as to how this happened give the extensive testing program that a camera like this goes through.
Canon realise that many of the AF configurations use by Pros are quite task specific and the AF issues only showed up in certain AF settings and shooting situations.
The AF 'problem' is seen as a very complex issue made up of:
Canon have been working through these problems and believe that with their latest firmware 1.1.1 the overall standard of AF is significantly better than the 1D Mk2N. However there are acknowledged still to be some minor issues to fix with the wide range of custom function AF options.
There might yet be a 1DMk3n - but given the 3 year development cycle this won't be decided until next year. Options include
See also 1D4 info... ;-)
16th I had a report form someone attending a 'pro' day in the UK, who had this to say about how the AF issues were addressed by Canon:
Thanks very much for the info!
7th The AF 'problem' won't go away, with rumours about large buyers 'demanding' a fix from Canon. A Reuters related thread at DPR is typical. If I was concerned about AF issues for a camera of my own then I think that RG possibly has the best (and most balanced) coverage of the issues.
1st See the excellent technical article at kammagamma for discussions about 1D3 noise reduction and what's going on in your camera when shooting Jpeg files
27th August Initial reports are that the new firmware improves AF in bright light (see link yesterday for an active discussion)
26th New firmware is now being installed by Canon service at the Osaka games (DPR)
"V1.1.1 firmware for the 1d MKIII - fixes more auto focus issues and the Error 99 problem"
Should be available for download 'in September'. As yet I've seen no reports on its efficacy.
Meanwhile, have a look at the 'is there an AF problem' poll on FM. It has people's serial number info in it as well. I've only spoken directly to three 1D3 owners and not one had noticed an AF problem (but then it's summer in the UK and therefore not too hot ;-)
I just don't do the kind of work that would really show this problem up - I'll have a look though when I finally get a 1Ds3, since the AF system is supposed to be the same...
23rd Nikon move to FF too (Nikon D3 info) Very interesting specs and well worth a look for 1D3 users - look to see some of these features in a 1D3N ;-)
20th Still no official comment from Canon over 1D3 AF problems experienced by some people.
We had a message from someone in Switzerland who was told, when asking Canon about the AF issues:
"I have no comment about this test [the RG AF tests] , most of our clients (Switzerland) are very satisfied with this camera!"
They also sent a PDF explaining how to use various CF settings... (a 500k PDF - mail me if you can't find a copy)
There is a very nice 63 page PDF all about the 1D3 (for a long read ;-) This camera has an awful lot of new features
New firmware from Canon for 1D3 - soon to be available for download
The new firmware for the Mark III should be generally available from: http://web.Canon.jp/imaging/BeBit-e.html at 10am Tokyo time (GMT+9) July 31st. It includes the following improvements and fixes:
Note -- Ariel Bravy has maintained a wide collection of info on the FM 1D3 thread

Canon today sets new standards for professional photography with the launch of the EOS-1D Mark III. Delivering 10 frames per second at 10.1 Megapixels for a maximum burst of 110 Large JPEG images (30 in RAW), the EOS-1D Mark III replaces the EOS-1D Mark II N as the world’s fastest digital SLR. Dual “DIGIC III” processors drive the camera’s high speed, high resolution performance, and bring 14-bit image processing to the EOS series for the first time. A ground-up redesign introduces a host of new features and advancements to Canon’s flagship EOS-1 series, including a 3.0” LCD with Live View mode, EOS Integrated Cleaning System, new auto focus system with 19 cross-type sensors, and 63-zone exposure metering. The camera’s APS-H size (28.1 x 18.7 mm) CMOS sensor enables a wider 100-3200 ISO range as standard, expandable to L:50 and H:6400. “The EOS-1D Mark III represents a complete reappraisal of everything Canon has learned over the past 20 years of EOS development,” said Tsunemasa Ohara, Senior General Manager, Camera Development Center, Canon Inc. “In building this camera, we started with a blank canvas. Every facet of the photographic process has been refined, every design decision re-evaluated to bring us to this point: a camera that combines familiar EOS ergonomics with a vastly enhanced specification. Our engineers are overjoyed with the result.” Key features 10.1 Megapixel APS-H CMOS sensor The EOS-1D line has enjoyed massive popularity among the world’s leading sports, reportage and wildlife photographers, with international wire agencies AFP, Getty and Reuters choosing Canon for their photographers. “The people at Canon is great to work with because they listen to photographers. It’s their attention to detail and the pace of innovation that makes EOS the system of choice,” explained Stephen Munday, Director of Operations Editorial, Getty Images. Exceptional image quality Canon’s dual “DIGIC III” processors deliver unprecedented levels of speed, responsiveness and image quality. Ready to shoot within 0.2 seconds of power on, the EOS-1D Mark III can capture and process over 100 Megapixels of image data per second, rapidly clearing the image buffer to allow up to 110 frames in one burst. Images are processed at 14 bits for a total colour depth of up to 16,384 tones per pixel, compared to 4,096 tones from 12 bit images. The third generation CMOS sensor incorporates a new pixel design that works together with on-chip noise reduction circuitry to ensure high image quality at ISO 3200. The option to expand to H:6400 will benefit professionals working in news and sports locations where the use of flash is not permitted or desired. Greater precision, more control Canon has redesigned its auto focus system to include 19 cross-type sensors with sensitivity up to f/2.8, spread out across the AF area to better accommodate off-centre subjects. An additional 26 AF assist points are used to aid AF tracking for improved accuracy. Responding to professional photographer requests, a dedicated AF button on the back of the camera allows users to instantly switch auto focus on or off while keeping their eye on the viewfinder. The viewfinder is now brighter and offers a wider angle of view. The camera’s new 63-zone metering system gives photographers greater level of control over exposure. New LCD with Live View The bright 3.0” LCD monitor provides 230K pixels resolution for precise framing and reviewing of shots. New to EOS, Live View mode enables photographers to frame without having to look through the viewfinder particularly useful for shooting from awkward positions. The menu system on the EOS-1D Mark III has been completely redesigned to take advantage of the LCD size menus are easier to read and use. A choice of 57 custom functions gives photographers more options for customising camera settings to their daily working requirements. A new My Menu option allows photographers to store frequently used settings on a separate menu for faster access. Settings for new accessories such as the Speedlite 580EX II and Wireless File Transmitter WFT-E2 also released today can be controlled directly from the LCD. Total reliability The EOS-1D Mark III incorporates a range of practical enhancements for the working photographer. Shutter durability has been increased by 50% to 300,000 cycles. The body is protected by a magnesium alloy casing with dust and moisture resistant seals. The EOS Integrated Cleaning System provides further reliability by reducing sensor dust, minimising the need for manual cleaning on assignment. To avoid corruption of captured images, a warning appears on the LCD and an alarm sounds if the memory card door is opened while images are still being written. Interfaces include video out (for display in both NTSC and PAL formats) and USB 2.0. Compatibility and accessories Canon is marking today’s launch with the release of several additions to the professional EOS system: EF 16-35mm f/2.8L II USM A fast, ultra wide-angle zoom lens delivering exceptional image quality throughout the aperture range. The EOS-1D Mark III is supplied with a comprehensive software suite to help the photographer’s workflow. This includes Digital Photo Professional (DPP), a powerful RAW converter that provides complete RAW image processing control. DPP integrates with cameras features such as the Dust Delete Data and Picture Style. The camera also comes with EOS Utility, ImageBrowser/Zoom Browser and Photostitch. |

Self-Cleaning Sensor Unit
Dust Delete Data Detection
Dust that has been missed by the Integrated Self-Cleaning Sensor Unit can also be erased with software included in Digital Photo Professional (DPP) Version 3.0. The 1D Mark III’s imaging sensor is able to single out the dust particles on its surface, then plots out their location coordinates within the image. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon’s DPP version 3.0. This added software option ensures the cleanest possible image, perfect for printing or archiving.

'smart' dust removal
World's fastest digital SLR:
shooting up to 10 fps (frames per second), with a burst rate up to 110 full-resolution JPEG images or 30 RAW images
With a maximum continuous shooting speed of approximately 10 frames-per-second, for up to 110 shots, the EOS-1D Mark III is the world's fastest digital SLR. Bursts are first recorded to the camera’s internal memory to ensure maximum speed and then transferred to memory cards for storage. The number of shots remaining during a burst is displayed on the right side of the viewfinder.
Photographers can expect an exceptional degree of performance and reliability exceeding any film camera they've ever used. Speedy shooting is achieved with an entirely new, lightning-fast 45-point AF system, sophisticated tracking and predictive AF technology combined with precise, instant metering, no matter the setting.
All new high-precision AF system with 19 user-selectable AF points and 26 additional "assist points"; superior low-light performance and faster operation
The EOS-1D Mark III raises the bar for AF performance. It uses an extraordinary 45-point high-density area AF system that provides not only the industry's largest continuous AF coverage area, but also the greatest range of control over focusing point selection. The focusing point can be selected automatically by the camera (based on high-speed microcomputer analysis of image content), or users can manually select any of 19 high precision, cross-type AF points which can be complemented by 26 additional Assist Points for pin sharp accuracy, instantaneously.
A processing unit devoted solely to focusing the 1D Mark III uses advanced algorithms that ensure the fastest, most accurate AF performance under the widest variety of conditions, with processing up to 3 times faster and a full stop darker than on the EOS-1D Mark II N. The One-Shot AF mode is ideal for more static subjects. The camera rapidly selects the optimum focusing point and the subject is instantly brought into focus even if it is off-center. The AI Servo AF mode is excellent for moving subjects. Aided by a highly "intelligent" predictive focusing algorithm, it precisely tracks subject movement, even at speeds of up to 10 fps. Even with erratic or rapid subject movement, the photographer can shoot continuously, concentrating solely on image composition.
New Custom Functions aid the photographer in choosing from default focusing points, as well as changing the size of a manually-selected AF point, making this not only the fastest, but also the most customizable AF system on the planet.

In response to requests from professional users, the new EOS-1D Mark III is more rugged, yet lighter than its predecessor. Able to withstand shooting in the roughest conditions, the 1D Mark III is clad in a magnesium alloy shell, chassis and top panel, providing impressive strength without excessive weight. All of the 1D Mark III controls and external cover seams are sealed from water and dust. Even the perimeter of the 1D Mark III’s hot-shoe is ribbed for water resistance, enabling flash photography with Canon’s new Speedlite 580EX II.
Other new features include an improved shutter, durability tested to 300,000 exposures, powerful new metering, a new control interface that mirrors the design of other popular EOS Digital SLR cameras and a 100% coverage viewfinder with a larger pentaprism for higher magnification, plus a number of optional focusing screens.
Canon is also introducing a new, lightweight lithium-ion battery system that provides feedback on the LCD monitor, including number of shots taken on a charge, percentage of battery power remaining and whether the battery should be reconditioned with the charger. With the new battery installed, the EOS-1D Mark III body is about 1/2 pound (approx. 225g) lighter than the EOS-1D Mark II N body.
