The question is why has Canon not released a 36MP'ish FF camera when both Nikon and Sony have done it.
So, if according to you, the ability of the processor(s) to handle the data is not the issue, then what is the excuse? Crummy lenses without the resolving power? No. Slow SD and CF cards? No. Inability to actually make such sensors? No. What then?
Or has Canon simply decided that absolutely no photographer actually needs 36MP in a FF package?
To those chucking Moore's Law around ... yes, possibly the DiG!C architecture can handle the data, but at what cost in terms of power consumption and thermal management? Both these factors can negatively impact on the actual use of the chips ... which leads to the same conclusion.
Nikon and Sony use the same sensors, correct?
How well does the 36mp Sony sensor hold up at say 3200 ISO and up compared to Canon? I know that a 12,000 ISO image from a 1DX is pretty much usable right out of the camera. The 5DIII does pretty good too.
I would guess that Canon will deliver their answer when they are good and ready. I do not understand the details of sensor fabrication, but I bet that Canon doesn't want to release a 36mp sensor that performs like the current 7D. Some like the 7D, some don't.
There is also the possibility that all of the people on photography forums screaming for a 36mp Canon sensor may not actually buy one when it is released (measurebators) or the sales lost to Sony/Nikon are insignificant in the bigger picture.
The people wanting 36mp so they can crop at 400% must be a small part of the market, certainly not enough to support a camera line.
I have done 11 x 14 prints from a Canon 1D with a whopping 4.2mp and those look pretty damn good to my eyes without a stand alone program like Perfect Resize (I just used DPP and tried out Qimage with the jpegs). I just got the 17 x 22 paper to try that out. So, do people want a 36mp camera to make 4mp crop prints of the image?
I don't have any inside Canon info, but I suspect that when their answer to the 36mp Sony comes out, it'll be a knockout punch (I bet they have bought 36mp cameras at retail and looked inside very intently). Even if it isn't a knockout but a step forward, Canon is a pretty diverse company. The measurebators wanting the 36mp sensor are eclipsed by the pro's wanting a system that works or the hobbyists that don't care.
I wonder what it will cost when/if it is released...
I wonder if people inside the Canon skunkworks laugh at these threads
