what so many people seem to forget is that Sony sensors work better at low ISO and canon sensors work best at high ISO. Nobody is best across the board. I think it would be a step backwards for the industry to just pick one.
The lead that the Sony sensor has at low ISO is much greater than the lead the Canon sensor has at high ISO. Furthermore the Sony sensor has a linear relationship between ISO and performance where the Canon sesnor does not.QuoteAnother point that needs to be made is that you can outsource the production of your design. It is very possible that Sony can produce a Canon design of sensor more economically than in house at Canon.
Or can produce designs that Canon cannot (due to fabrication process limitations.)
Canon make steppers, part of the machinery needed to make sensors, Sony don't.
Well in that case it means that Canon is behind in another area of its business (whoever is making the plant equipment that supplies Sony or the company that makes Sony's sensors.)
There are three companies in the world that make steppers, Canon, Nikon, and ASML a Dutch company. I believe they all make the same generation steppers, though Nikon are well off the boil, and Canon lost a lot of market share to ASML as well due to very restrictive and proprietary attitudes. ASML have carved a substantial portion of the market out for themselves because of business practices, not technology.
