The sensor from Canon is almost good as from Sony/Toshiba etc. Canon are little bit behind in QE with 50% compare to the best Toshiba 65% Sony 56%.
The DR problem starts when Canon reads out the signal from the sensor , Canon have long analog signal path way. And this shows at base iso with high read out noise, pattern noise banding and therefore 11-11,7 stops DR compared to others like Sony with 14 stops and even little more.
More Mp-when?
To use the latest APS line and make a 24x36mm sensor with the same structure as the 18Mp sensor in 7d will be expensive and time consuming because APS line will be occupied, Canon has no steppers, lenses to expose a 24x36mm area in one time with smaller geometry/scale as its needs for a new sensor tech as Sony, Toshiba, Panasonic with for example column wise ADC on-board the chip. Canon can stitch the sensors but also that is time consuming and costly
Canon has neither the whole assembly in house, the turn themeselves to Fujitsu
Compared to Sony who has 5-7 lines and down to 90nm (and even smaller) Canon has two older lines.
have you been to canon's sensor fab plant? you're making alot of assumptions that you actually know first hand what canon has or doesn't have in house.
it's been rumored since around the 5D mark II timeframe that canon is producing full frame sensors with one pass.
I'm curious by alot of your assumptions - because canon has a 180nm line already in production. they have already produced sensors in production quantity with 180nm technology. We don't know what they've been scaling up to ASP-C sizes, but canon does spend a high amount of money in R&D and development. it's not as if they are starting from scratch.
The going theory is that the current 180nm is running at full capacity that canon cannot scale up that line to support APS-C or full frame sensors. however, if there's a place for canon to put out the 180nm sensor first it would be in the far easier APS-C based camera body .. which is being eluded to with the 7D Mark II release.
you claim they've hit an engineering wall..

this was a while ago - apparently they haven't.
now I would imagine with 2.1um pixels - what's the odds it was created with 500nm tech?
could it be that canon's been working on it - for perhaps a while now?
Where can I get that sensor? What kind of read out? QE, FWC ?????
I'm sure if you are qualified, canon would most certainly love your input to their R&D.
Canon has not the equipment to make high resolutions 24x36mm sensors with new tech as Sony et al.
and you know this how?
180nm tech ? others are down at 90nm regarding APS
and that's immaterial to this forum where the most modern FF sensors are 180nm and in some cases such as the D4 sensor - it's using 250nm.
The biggest research is going on and around the mobile cameras sensors ,and the market is huge, Canon has no such research
you know this how? canon of course, never publishes patents on any sensor technology.. ever. they obviously never do any research.
you make alot of bold statements - with zero fact.
1.there are no sign in any annual report or other paper that Canon has invested billion of dollars in new sensor lines .
In 2012 Canon invested $894 million US in Imaging Systems R&D and a further $1.06m billion in Office Business Unit R&D and these are projected to grow by a further 8.3% in 2013.
In the same period Canon projects that its increase in plant and equipment will be $3,846 million US. Granted they are not being specific as to the breakdown of this expenditure but would you expect them to be?
2.There are no rapport telling that Canon have invested in new optics from Carl Zeiss or steppers from Nikon or ASML .
This level of detail would be a bit like you reporting that you have invested in a new UV filter.
3.There is no sign what ever that Canon has any new sensor technology ready to go.
Perhaps that's deliberate. Why inform the world what you plans are if you don't need to?
