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]

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"

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.

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

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]
