Keep in mind that the 7D pixel pitch is 4.3 microns wide on a 0.5 micron process.

I've said it before but I'll repeat that:
if we see Canon increase the MP on their new APS-C cameras, the process CD will HAVE to be smaller (hopefully the newer 180nm process).

Having said that, all the rumors point towards a 20+MP camera which is definitely an encouraging sign.

excuse my ignorance - but what will the 180nm process help?

i thought that the larger photodiode (up to a point) helped make a cleaner picture (i am sure that my understanding is simplistic...so please help me understand!) :)

thanks

Sure thing.

A "larger"/older process (i.e. 0.5 micron) means that the smallest feature size you can make (also called CD critical dimension) is 0.5 a micron.

So if you have metal traces that are at a minimum 0.5 micron wide on a 4.3 micron photosite, you can now see that the electronics involved (transistors, diodes, resistors, etc.) that are connected with metal traces, are obscuring a portion of the photosite thus making it less efficient.
It also prevents you from "going smaller" i.e. more MP.
With a smaller process you can also fit a lot more circuitry on there for more A/D conversion, lower noise floor, higher DR etc.

That's why I keep saying that if the new APS-C sensor will be >20MP, it will HAVE to be using a smaller CD process (i.e. 180nm).


Think new Canon lenses are overpriced? Lots (and lots) of data will set you free!

I keep hoping for backside illumination tech to make it into the DSLR sensors, which would avoid this issue. So far, commercial backside illumination sensors have all been very small (e.g. cell phones), but it is this tech that helps make the cameras in, for example, the iPhone 4 and later so good.

Yeah, that would definitely be great.
Let's hope that Canon will blow us away with surprises post-Summer.
As I said, hope dies last! :D

My vote...(or wishful thinking)

Its going to be the 7DX. Its going to be a crop sensor in a 1DX body.
FPS will be slightly reduced from 1DX, to around 9-10 FPS.
It will have a new sensor, around 20-22 mpx, and will set a new level for DR and iso.
Will have toned-down version of the 5D3 AF system.
Will have "burst" bracketing. i.e.; something like 9 shots over 3 eV in 1/3 increments.
Bracketed shots will be merged in-camera for amazing HDR output.
1080/60 video, mic input, headphone output, adjustable mic level.
Dual memory slots, one CF, one SD.
Built in wireless transmitter. Live view on your PC / handheld.

$2199 MSRP

It would be really nice to see these things in the 7dmkII. I like making videos, so 1080/60 combined with the new video technology on the 70d would be fantastic.

Any chance of this camera having a built in flash? Likely not I'm guessing.

Interesting.

Two pro bodies not including the 7DII.

wonder whats going on. 1DX is pretty new still and supposedly the merger of the 1D Line. New Sensor that is good enough to replace the 1DX already and a studio high MP body?


---------------Camera, Lens, Flash stuff.. but still wanting more

Why 24.1MP and not 22?

That way we'd have:
the 70D & 6D at 20.2MP
and
7DII & 5DIII at 22MP.

Makes sense as far as MPs are concerned.

That makes sense to me. I initially thought it was a oddly arbitrary that they made the crop-sensor 70D have the same resolution as the 6D. But, aligning the resolutions like that starts to say something about the alignment of the cameras: that the 7D II is a crop-frame counterpart to the 5D III. As a 5D III owner wanting/needing a crop-frame camera, I'd like that very much.

Also a 22MP seems more likely as Canon has apparently thrown the brakes on the MP escalation. It sure would be nice to see something impressive from Canon sensors for a long-overdue change.

OK Canon, wonderful work on the latest AF advancements (7D, 5D III, 1DX, and 70D) - thank you! - now would you kindly go to work on your industry-lagging sensors? :)

A little disappointing but not a surprise that it wont be out until next year. I am in one of those in between periods of camera body releases thats full of compremise. Also its funny how you always want what you cant have yet ;)

It's not that they have thrown on the brakes, the wafer manufacturing process they are using is very very old and will not support the sizes needed to increase resolution.

Your manufacturing process insight is appreciated. :)

Whatever they might need to do to develop higher MP sensors they've clearly elected not to do it...for whatever reason. I still think it is reasonable to call that "throwing on the brakes" because they have/had the ability to advance their processing abilities to match Sony's advances, or hit the brakes on sensor R&D and just make incremental sensor improvements for several years, and they have chosen the latter. At least that is how it appears. ;)
