The rumour pages have been published by Keith Cooper since 2004 as part of our wider Northlight Images photography site. Please do use your common sense when reading these pages, and remember that they are here for entertainment as much as anything else. Remember that rumour accuracy plummets once you are more than a few months from any 'announcement'.
Unlike some 'rumour sites', we don't hide behind anonymity and have no connection with any camera companies (or their PR agencies).
Buying anything via our links costs you nothing more, but helps me expand the site. There is just myself writing and maintaining it

15th The compact flash association (CF makers trade club) has announced a new standard that they are working on. The CFExpress standard would have a theoretical maximum thoughput of 8GB per second.
Read more in their press info [PDF], although we're some time away from any real products
CFA’s goals for the Cfexpress family are:
1) Unify the ecosystem around a removable storage specification that has longevity in the market
2) Provide a platform that scales with performance increases in the PCIE interface
3) Leverages the technologies and skillsets of the larger volume compute markets
4) Seamless compatibility with the capture ecosystem and workflow tools.
The chart below (at MR) goes alongside the news that the Quesabesde photography web site is shutting up shop [QB via Google xlt]
As a Spanish site it's not one I check often, but has been going for 15 years (Northlight appeared in 2002, with the first reviews and articles in 2003 and the first rumours in 2004)
The translation above is quite readable and recounts how empty the recent Photokina was compared to a few years ago, along with the general changes that led to their closure.
The photo market is changing and all of us working in different parts of it need to move along...
14th An interesting chart showing CIPA camera shipments over the lifetime of this site.
It's not good news for camera companies.
Of personal interest, it broadly marks the overall traffic for the rumours pages of this site...
However, the traffic for articles and reviews has steadily risen over the period :-)
I've been working on an all new version of the site for quite some time (it's huge and I have a day job) and whilst it will still have a rumour update section, it will be simpler and I'll be expanding the news, reviews and articles (suggestions welcome).
The more new kit I've tested of late, the more I realise that these days, the limitations are far more likely to be behind the camera ;-)
A Canon patent for a folded optical system in an optical viewfinder (OVF) The secondary sensor at the top meters the image on the focus screen and can be used for other mirror down functions, such as tracking and face recognition.[EG via Google xlt]
Higher resolution secondary sensors need a better optical system, which would normally take up too much space in the crowded prism area, but the particular benefits of this one need a better understanding of the Japanese text than the translation offers. The combined prism/lens element (19) is an interesting one.
Other cameras get an update to address a lens incompatibility.
"Corrects a phenomenon in which when using the camera with the EF-S 18-135mm f/3.5-5.6 IS USM or EF 70-300mm f/4-5.6 IS II USM lens, even if lens aberration correction is set to “Enable”, correction will not be applied."

Nikon [PB] - No, the Nikon 1 isn't dead ... really
23rd Patents with interesting uses for image sensors [ISW]
- A system and a method for guiding a user during shaving
- A camera in a violin, to help with correct fingering
- Solving a problem of rolling shutter distortions when the refrigerator door opens
21st Canon's showing their 120MP APS-H sensor in a 5Ds body at Photokina [EPZ]
Only 19 seconds to download an image... (using 5Ds circuitry)
Yes, I'd quite like the ~200MP full frame equivalent. Having spent the day producing a collection of 22"x14" and 22" x 33" prints for a client, I really appreciate the benefits of my 50MP 5Ds. The images came from my 1Ds, 1Ds3 and 5Ds - I compared prints from the three in a detailed article a while ago [comparing 11MP/21MP/50MP for printmaking]
20th If you use some Canon software (especially printer drivers) and Macs, think carfully about updating to MacOS 10.12 (Sierra)
So, it looks as if Canon has finally decided to get a bit more serious with the mirrorless range, putting the 80D sensor in a body the size of the 100D (who now expects the 100D to be updated?)
With a quick look at the specs, I notice a rather low number of shots per battery charge - looks like you may need a pocket full of batteries for a day's shooting with a lot of EVF and rear screen use.
The new 70-300 brings Canon's first LCD display for a lens.
Looking at how the presence of a physical indicator scale constrains lens design and manufacturing, I expect we'll see many more examples of this with upcoming longer lenses. The distance info was always there for many EF lenses, it looks as if now Canon have improved its absolute accuracy and the cost of LCD units has come down enough to warrant electronic displays.
14th The last minute leaks before Photokina seem to be coming aplenty, with detailed specs of lenses and the EOS-M5, which from a size POV, looks like an EVF based 'mirrorless' update for the 100D/SL1 (Mirrorless page)
8th If you've a 7D2 and want to use the new WiFi card from Canon, you'll need the latest firmware update (V1.1.0)
Firmware Version 1.1.0 incorporates the following functional enhancements and improvements:
Supports Wi-Fi adapter W-E1.
Adds a setting to enable or disable automatic storage of the lens if it is extended out when a gear-driven STM lens*1 is attached, and the power switch is turned to [OFF].
*1 EF 40mm f/2.8 STM, EF 50mm f/1.8 STM, or EF-S 24mm f/2.8 STM lenses
Slow rumour updates - Keith is having a break ;-)
2nd A Canon patent [EG via Google xlt] expands the idea of compound cameras (multiple focal lengths at the same time) with a folded optics system.
31st DPReview puts the 5D4 dual pixel focus adjustment feature in DPP to the test [DPR]
As might be suspected by anyone with more than a cursory knowledge of optics, the effect is rather small.
Cue a certain amount of whinging on forums :-)
Expect to see rather more serious use made of the split pixel RAW data once people start working on it. I'm pleased to see Canon adding stuff like this to a camera.
In a further offset microlens patent [EG via Google xlt] another aspect of the asymetrical pixels micro-lens is explored, this time light scattering. Compare with diagrams from a few days ago (Aug 19th).
Canon announce a new higher DR global sgutter CMOS imaging chip [Can] - not due in a DSLR any time soon...
"Distortion-free image capture when shooting fast-moving objects
Standard CMOS sensors make use of the rolling shutter method, which sequentially exposes the pixels one row at a time. Because rolling shutters can create slight discrepancies in signal-readout timing depending on the location of the pixel, images of fast-moving objects may appear distorted and flash photography may result in the occurrence of the flash band phenomenon, in which the upper and lower portions of images display different levels of brightness. Because Canon's newly developed CMOS sensor employs a global shutter, when shooting such fast-moving objects as a rotating propeller or a speeding train, subjects are able to retain their proper form to create distortion-free images. Enabling the confirmation of object shapes with a high degree of accuracy, the sensor offers potential benefits in industrial applications, including as a sensor for use in inspection cameras.
Wide dynamic range realized through new proprietary drive method and pixel structure
When the newly developed CMOS sensor converts light into electrical signals and stores the signal charge in memory, the new drive system achieves a significant expansion in full well capacity. Also, because it employs a structure that efficiently captures light and each pixel incorporates an optimized internal configuration, the sensor makes possible increased sensitivity with reduced noise. The expanded full well capacity, realized through the sensor’s new drive system, and substantial reduction in noise, enabled by the new pixel structure, combine to deliver a wide dynamic range, facilitating the capture of high-image-quality, high-definition footage even when shooting scenes containing large variances in brightness.
Canon will explore various industrial and measurement applications for the newly developed CMOS sensor and consider deploying it in the field of video production for cinema production applications, TV dramas, commercials and more."
30th I was recently asked what was the best printer currently available? Not a question I'll answer, and I've written up why at "Why I never recommend the best products" - hope it's of help in understanding the reasoning behind the hundreds of reviews I've written over the last few years.
7Dmk 2 firmware to control the new WiFi card will be available soon (7D2 page)
29th A Canon patent [EG via Google xlt] shows how by replacing the sub mirrors with laminated diffraction gratings, the normal angle of reflection can be altered, adding or subtracting to the usual angle.
In the example of the 5Dmk4 this is used to expand the vertical coverage of the AF sensor array (this technique could explain the improvements in the 1D X mk2 as well).
28th A whole load of Canon products are registered in Russia [Nok]
This is required where products have wireless functionality.
What DSLR might appear so soon after the 5D mk4?
A bit soon for the 6D mk2 - how about a 100D replacement
Note that some of this stuff might not be new - it's Russian info appearing on a Japanese site, translated by Google... That DSLR might even be the 5D4
25th The 5D4 has new features that makes use of Dual Pixel data, if recorded (doubles the size of RAW files) and currently only usable if you process images with DPP. There is a Canon article explaining the dual pixel AF adjustment functions.
In addition to all the adjustments you can perform using Canon’s RAW processing software to RAW image files, EOS 5D Mark IV images shot with Dual Pixel RAW active also allow the following adjustments:
Make subtle changes to slightly alter the plane of sharpest detail in an image, using depth information. You can microadjust the sharpest detail forward (toward the camera) or backward at the subject.
Take out-of-focus foreground and background information, and shift it slightly (side-to-side in a horizontal shot), using sliders in DPP to vary the range of adjustment. The primary, focused-upon subject remains essentially unaffected — so the out-of-focus areas do in fact shift a bit. This can be easily seen once you bring Dual Pixel RAW images into your computer.
Select an area of the frame having flare or ghost images from light sources which are just ouside the visible frame, and DPP can process the image to reduce these aberrations in some cases. You select the area by drawing a box around it, on-screen, in DPP’s preview window.
Just how well this is going to work remains to be seen...
There is at the end of the article...
- According to Canon, Inc. engineers, best results will tend to occur when images are taken at wide lens apertures (low f-numbers). As an image’s depth-of-field increases, Dual Pixel RAW’s ability to make significant visual changes decreases.
- Focus distance matters between camera and subject, too. In general, the impact will tend to be greater at near and middle distances for a given focal length lens than it will if the lens is focused upon truly distant subjects.
- No exceptions: to have the ability to perform these operations within Canon’s DPP software, the actual image must be taken with the EOS 5D Mark IV’s Dual Pixel RAW menu option enabled before the shutter is fired. RAW images can certainly be taken with Dual Pixel RAW disabled, but you will not be able to perform these additional changes to them.
- To repeat, Canon, Inc. and Canon USA have no idea if or when any competitive, third-party RAW process software programs may develop Dual Pixel RAW process capability. With EOS 5D Mark IV RAW files, taken with Dual Pixel RAW enabled on the camera’s menu, know that you can process them and make Dual Pixel RAW adjustments with Canon’s DPP software — version 4.5 or higher — and that software is included with the EOS 5D Mark IV camera. It’ll also be available as a free download from Canon web sites.
- Dual Pixel RAW images are only possible with the EOS 5D Mark IV, as of mid-August 2016. We know of no plans at present to add this feature to previous EOS models that have the Dual Pixel CMOS AF architecture (EOS 70D/80D, EOS 7D Mark II, and EOS-1D X Mark II, for instance).
"EISA is the unique association of nearly 50 special interest magazines from 23 European countries. Internationally known for the European EISA Awards, EISA started in 1982 when the editors-in-chief from five European photo magazines came together to select “The Camera of the Year” for the first time. They had no idea that out of this meeting EISA - the European Imaging and Sound Association - would emerge some years later. This historic moment took place in 1989 after another 10 photo magazines had joined the group in the meanwhile."
It seems there is still a place for grand shindigs meetings in nice places...
Meanwhile as the band plays on, camera shipments decline [CIPA pdf]
...and Sony decided to ease off on CMOS sensor development [ISW]
7th The WiFi card is suggested as a $40 product [CR]
Specifications of Wi-Fi adapter "W-E1"
- Size: 24.0mm x 32.0mm x2.1mm
- Weight: about 2g
- Operating temperature: 0-40 degrees. Humidity of 85% or less
- Transmission scheme: IEEE802.11b / g / n
- Transfer range: 10m
- Allow the camera of a remote control from the smartphone
- Remote operation possible wirelessly using EOS Utility
Fits in an SD card slot - so should be good for other cameras too?
14th Is this the 5D4 on its way? An Indonesian certification authority mentions a new Canon camera manufactured in Japan, with WiFi and GPS
Canon registration contents
- Equipment: Digital camera
- Model name: Canon DS126601
- Manufacturing: Japan
- Date: July 1, 2016
Could be something else, but we're in the right timeframe for the 5D mk4
11th An interesting Canon patent puts polarising elements in front of some groups of pixels on a sensor, with the aim of improving sensor based AF with no movement of the lens focus elements. [EG via Google xlt]
The polarising elements alternate the plane of polarisation.
Whilst final focus might require some back and forth focus movement, the better estimate for initial movement you can get, the faster and smoother the focus action is.
The patent used a full frame 300/2.8 lens as an example - note no mirror ;-)
In a patent from Samsung [ISW], the colour filter array is replaced with beam splitters.
This means that some of the coloured light normally lost in filtering is pushed into adjacent pixels for that colour
Samsung have related patents in October and February of last year (2015 rumours/news)
3rd Add the earthquake hitting sensor supplies (for everyone but Canon) to the ongoing slide in camera sales and you get the worst figures yet for shipments from CIPA.
For some analysis of the figures see Thom Hogan's comments [TH]
Rumours have gone fairly quiet of late, but I'm hoping for a pickup this month, as we get closer to Photokina camera releases.
I'm looking for a distinct sea-change in rumour quality as wish lists and guesses drop out of the way for 'real' stuff, and the rumour sites are not just lists of 'deals' ;-)
BTW I've still got a 24" Canon PRO-2000 printer here for review - if anyone has any questions, please do let me know. It has a few distinct differences to the PRO-1000 I reviewed, but print quality is similar (i.e. excellent).
28th Canon have acknowledged a problem with the 1DX2 and some SanDisk CF cards, leading to image corruption.
24th A 'no 6D2 until 2017' comment [CR] includes a suggestion that there will be a new model designation in the EOS range.
Surely not the long expected 3D or 9D or 8D or 4D or 2D or something entirely new...
The Hasselblad mirrorless reminded me just how little real pushing the boundaries we've seen from Canikon - have a read of Thom Hogan's interesting take [TH]
16th I was recently interviewed for Episode 42 of the Breathing Color Podcast.
Karen recommends my 20+ minutes spot, talking about how to make a living in photography, as an excellent counter to insomnia. There is even a transcript, for those having difficulty with my Suffolk accent ;-)
15th Selling cameras in small quantities is a tough business - have a read of Thom Hogan's comments about why small camera shops find it so hard, and why the camera companies will push many out of business (and then wonder why)[TH]
Meanwhile - here's something for all those 5x4 sheets some of you have laying around. Pentax (Ricoh) announce a 5x4 duplicator. [PxR]
...available in 4x5 for those of you in the US ;-)
3rd The April CIPA figures are out and the bump in March this year, that led some to dream that the decline was over, reverts to form. There are more details available [PR] but Thom Hogan usually posts the best thought out observations on these figures in due course.
I'm inclined to wonder if the bump (shipments not sales) was more the result of companies wanting to shore up figures for their annual reports or trying to meet other forecasts.
25th In a Sony financial announcement it includes this: "...terminate the development and manufacturing of high-functionality camera modules for external sale." [ISW]
Does this mean advanced sensors (MF 100MP for example) or does it refer to complete camera units, such as might be found in phones or the innards of the old Hasselbling range?
A Canon PRO-2000 printer turns up for me to review - then leaves again, since when loaded with ink it can't be tilted and is too big to get into our house :-(
22nd Even if I use Canon equipment, I want Nikon to push Canon and the photography business forward - Not so good signs though in a deeper look at Nikon figures by Thom Hogan [TH]
20th Sorry for the paucity of rumours this week - Keith's on holiday
A 5Ds body with a 120MP sensor appears in China [DCF - xlt]
That's RAW files around 210+MB a nifty 13,248 x 8,832 resolution. Having seen the improved quality of 50MP 5Ds files over my 1Ds3, I'd have no difficulty with 120MP. Let the 'files too big 'whinging start :-)
The DLO feature of the 1DX 2 causes problems with some Sigma lenses - problem? -- Turn Peripheral illum. corr. to OFF for that lens [SLRL]
6th Looks as if the Speedlite 600EX-RT may well get an update shortly [CR]
4th Thom Hogan gives his usual succinct overview of camera sales figures [TH] As ever, compact cameras continue their slide, but mirrorless figures? well, 'it depends'...
Still no sign of organic based sensors, but a Toshiba patent (and hence likely available to Sony) covers a different molecule with a different spectral sensitivity [EG via Google xlt]
29th A Canon patent uses a variable light transmittance element to enable aperture to be altered without adjusting shutter speed [EG via Google xlt]
It's it's like having a variable ND filter in place that's coupled to the aperture setting (or T stop for video)
As you open up the lens, the exposure is maintained by reducing the amount of light let through, so that you don't need to change ISO or shutter speed, just pick your required DOF
One for the video crowd - I rarely ever use filters, so no obvious use springs to mind. I guess it might be easier to use flash outdoors in bright sun so YMMV ;-)
25th A new Canon patent looks at offset microlenses. [EG via Google xlt] above the colour filter (F).
Towards the edge of a sensor, obliquely angled light from a wide angle lens can partly miss the underlying sensor part of a pixel (PD).
This can be mitigated by offsetting the microlenses (ML).
The degree of offset increases away from the centre of the sensor.
Unfortunately if you want to use different types of lens, such as telecentric designs or even just a long focus lens, the rays now hit the sensor at less of an angle, and the offset lens causes some light to be lost (L1), leading to vignetting.
Canon's patent uses lenses of a more complex shape that are not offset.
The shape of the lens 'leans' towards the centre of the sensor (although not clear in the limited detail of the translated patent, this would mean the lenses would lean in different directions and amounts across the sensor).
These leaning lenses work with a wide range of incident light angles.
A further refinement uses dual lenses so that the light does not need to be internally reflected from the surface of the lightguide (LG) - think of the lightguide as a sort of funnel for photons, part of the chip's structure - not a lens
This second lens (IL) may also ease the need to vary the lens shape by quite as much across the sensor.
As an aside, I'd note that this whole problem becomes more serious as you reduce back focus distance for a camera system. It would be much more important if you wanted to put a full frame sensor in an EF-M body...
22nd Sony make sensors for a lot of companies. Damage from a recent earthquake may shut down manufacturing for a while [Sony] Canon use their sensors for several smaller cameras, but APS-C and FF sensors are their own. Hardest hit will be companies like Nikon and obviously Sony themselves, but many other companies rely heavily on Sony.
20th A Canon patent covers the addition of WiFi/GPS to cameras with metal bodies [EG via Google xlt]
16th The runes are cast [CR] with guestimates of...
5D4 Aug 16 | High End M Oct 16 | 6D2 Feb 17 | M4 Feb 17
Time to wheel out the timeline again...
The 750/760 should last into next year too, and the still excellent 100D could linger on with a Digic 6 version next year. (I'm currently testing the Venus 60mm macro and 15mm shift macro lenses with ours)

Note: dates start in announcement quarter, not shipping dates.
12th In the UK, there are a whole range of Canon lens/camera rebates currently running - there is a page with all the various combinations and deals at Park Cameras
7th A Canon PRO-1000 printer has just turned up for a review - questions? feel free to email me...
6th For a detailed and interesting view of the CIPA figures (graph below), see Thom Hogan's remarks [TH]
4th I was updating the Canon s/w page and noticed that the latest version of DPP (4.4.30) adds support for quite a few older cameras.
"Newly supported PowerShot G7 X Mark II, EOS-1D X Mark II, EOS Kiss X80 / EOS REBEL T6 / EOS 1300D, EOS 80D, EOS Kiss X4 / EOS REBEL T2i / EOS 550D, EOS Kiss X3 / EOS REBEL T1i / EOS 500D, EOS Kiss X2 / EOS DIGITAL REBEL XSi / EOS 450D, EOS Kiss F / EOS DIGITAL REBEL XS / EOS 1000D, EOS 50D, EOS-1Ds Mark III, EOS-1D Mark III, PowerShot G16, PowerShot S120, PowerShot G1 X"
2nd A few bits of info about the new K1 FF Pentax in a trade show interview [IR] see also the Pentax K1 site [Px]
29th The CIPA camera shipment figures for January are out - only one data point for this year, but I don't see this years curve being much more than a lower version of the two previous years above it.
23rd A Canon patent for a hybrid viewfinder. The light from the EVF (top centre) is reflected left and then right to the eye. The split prism below the EVF combines this info with the normal view [EG via Google xlt]
14th Several years ago (2005) I was talking to some people at Canon about developments in the camera market and how they regarded the competition. Nikon, was well ... they were Nikon and would develop cameras for pro photographers and support them. Sony was the bigger 'threat' from a technology POV, but would never gain traction in the 'Pro' market without a significant investment in the support services that are vital to many working pro photographers.
What reminded me of this?
A short article by a pro photographer in Australia [PP] explains why he's given up on Sony kit for his work.
Note - I have absolutely no problem with considering Sony kit for my work from a technical view, but I want to know that if it goes wrong, I'm going to get the same sort of service that I've come to expect from Canon. When your living depends on having kit available when you need it, things like this are something you take notice of.
10th After some pretty solid leaks, the Canon 1300D/T6 is announced [1300D page]
Not available until mid-year, I should have a full review when one is available to look at.
3rd Radar for your DSLR? A Ricoh patent uses radar to estimate distances to make it easier to remove the effects of mist and fog...[EG via Google xlt]
A Canon patent uses a fibre plate (3) to couple a curved plane of focus to a flat sensor (4). Very wide angle in this example. The bottom diagram shows how total internal reflection takes light through the plate. [EG via Google xlt]
Such plates of fibres have been round a while, such as in an image intensifier tube assembly I've got in my 'junk box'. They have never been cheap, so this patent is likely for a quite specialised use
1st Interesting Canon interview - Canon are still waiting for better AF and VF for mirrorless [DPR]
We were just sent a new video about the 1Dx2, including 1Dx 2 video footage - see the 1Dx2 page.
A Canon US patent shows a deformation of pixel microlenses towards the edge of a sensor, so as to improve responses for off axis rays. [USPTO]
26th -- Reviews info: I've just had an Epson SC-P7000 turn up for review. If anyone has any specific questions, please email me?
Version 1.1.0 is of the ColorChecker passport software is available from X-Rite - it fixes the 40MP limit for DNG files from earlier versions, and works for Lightroom 6.1
25th A Canon patent [EG via Google xlt] adds sensor movement (back and forward) to improve contrast AF
Here's an animated version of the diagrams from the patent
Note the flexing element (blue) below the sensor (red), which bends to move the sensor part back and forth
23rd APS-H is back!

12th At the ISSCC conference ('all about sensors') Canon presented a paper on their 250MP APS-H sensor.
There is info about this by Albert Theuwissen [HI] along with other papers presented.
There are also useful notes on the Panasonic organic sensors covered below a few days ago [HI]
One of the problems you get with a pellicle mirror system is that the tilted mirror that light from the lens travels through to the sensor produces a tilt in the focal plane.
Due to ship April 15th in the US and May in the UK.
In the UK there's a Canon offer, where if you order and register your Camera by the first of October, they will send you a free 64GB CFast card and reader (see 1DX2 page)
1st The details for the 1D X mark 2 are published early by a US dealer - no doubt getting an interesting phone call from Canon on Monday morning.
So, from a rumours POV, what are we going to get for the 1D X mark 3?
The 3/4 year life of the 1D X makes for an announcement in 2019/2020.
Extend the specs and you get 8k video and 25+MP (OK, lots more for proper 8k)
Looking at the patent below does make me wonder if we are finally going to see a raft of new sensor designs appearing, or whether there has been so much development of Bayer style sensors that it makes the barrier to their wider introduction a bit steep? Canon have dropped some pretty strong hints that much higher MP counts are on the way and their marketing department would love a 225MP (75MPx3) full RGB sensor. The only problem is whether such stacked pixel designs are really good enough (Sigma still keeps saying so)
There is also the matter of how you combine this with split pixel AF - something not directly covered in any of the recent patents, but a ~20MP APS-C split pixel full RGB sensor would make for high quality video too.
Once such a sensor is available, where do you slot it into the Canon range?
27th Time for a three layer stacked non bayer sensor from Canon?
A Canon patent [USPTO] showns a three level sensor (back illuminated unlike some previous patents)
The multi layer sensor has been around for a while in patent land (see below on this page and earlier archive pages)
The patent covers a lot of different aspects of how the different layers could be laid out in a practical sensor
Calibrate your own AF?
A Canon patent [USPTO] covers AF calibration for individual focus points and lenses
It includes this screen interface example
Something for the 1D X mk2 and 5D4?
A Canon patent [USPTO] covers the design of phase detection sensors (such as we may get to see in the 1DXmk2)
A Canon patent [USPTO] covers on chip A->D conversion.
When you have lots of split pixels for AF, then reading them out quickly can be an issue - discussed in US Canon patent [USPTO]
Canon's 'light field camera'...
More ways of splitting up light into different areas under a pixel microlens - so called 'light field' sensors [USPTO]
Note that the patent doesn't really discuss what you do with all the information from the pixels, although one part mentions an example of an 8MP sensor, composed of 128 million sub-pixels
24th Canon's involvement in the 'mirrorless' market has definitely been a bit hit and miss. Is it time for something 'different' in the mirrorless line on its way from Canon? [CR]
22nd Tiime for a hefty rise in the price of film [PR]
"FUJIFILM Corporation has announced that it will implement a worldwide price increase for its photographic films. The price increases are substantial and it would be an increase of at least double digit, but will vary depending on products, markets and regions."
A good interview at [DPR] includes this (and much more) from Fuji, putting the rise in perspective
dpr: Do you think film in general will have a resurgence?
TT: No, I don’t think so. The infrastructure [is no longer in place]. We have to continue to supply film and maintain our labs for another 10-20 years, maybe but I don’t think we can change the [downward] trend.
dpr: You mentioned in your presentation that demand for film peaked in 2000. Can you give me a current idea of how that compares to demand today?
TT: We sell less than 1% of that amount now. Across all formats. But we have to supply film to photo enthusiasts. They demand it of us, so we do.
If your serial number starts AEGL, then it's possible there will be an ink leak.
"We have determined that some imagePROGRAF PRO-1000 printers may experience ink leakage.
This announcement conveys Canon’s service policy for affected printers. We offer our sincerest apologies to any customers who have been inconvenienced.
In rare instances, ink may leak from inside the printer to the outside of the printer through an opening on the bottom.
imagePROGRAF PRO-1000 units starting with serial number prefix AEGL. Example: AEGL01234
The serial number can be found on the back of printer."
11th Samsung may have got out of the camera business, but the have a stand at photokina in September.[PR]
6th An interesting patent from Canon seems to show a moving sensor to switch between mirrorless and SLR modes of working [EG via Google xlt]
Of course, photokina isn't just cameras - Samsung have some interesting monitor developments to show too, that and phones these days seem capable of rudimentary photography too...
Short back focus lenses such as EF-M allow you to put the sensor much closer to the lens, reducing body depth. However, unless you choose an EVF, there is no way to get a good optical reflex viewfinder. The patent allows you to swap between a focus screen or sensor close up to the lens.
Perhaps a bit clearer to see in this animation of the short backfocus reflex viewfinder design.
The sensor is red and the focus screen green (other moving part is a mirror)
This allows a reflex optical viewfinder to be used with any short backfocus lens.
5th It's the CES show, so Canon have announced a heap of consumer kit. The compact camera isn't quite dead yet [DPR]
27th Time for on-chip A/D conversion for Canon sensors? A Canon image sensor patent [USPTO]
