Nope. Personally, I don't want Canon to use Sony sensors. I want Canon to become the force that makes Sony innovate harder and faster, by innovating harder and faster themselves. I want Canon to step up their sensor manufacturing game, and become a bigger player in the image sensor market, against Sony, Aptina, Omnivision and other companies. I don't expect Canon to start selling their sensors openly on the market...but I do want them to join the fray and become a solid competitive force that keeps sensor technology progressing for digital cameras.
There is a TON of sensor innovation these days, however the majority of it seems to be getting done in much smaller form factors, and for sub markets other than digital photography...things like security video, cinematography, car rear view sensors (booming new market), astrophotography (sony changed the game there as well), etc. The only major innovation I've seen Sony make in the digital photography market since the introduction of the Exmor...what, maybe around five years ago now in the K-5 (?)...is the minor changes for the A7s, and the coupling with BionzX for digital signal NR.
I would really like to see Canon introduce a game changer. A layered sensor with at least 14 stops of DR would be disruptive at the very least, for a little while. That kind of full-constituent spatial resolution with that much DR would be...amazing. It should spur the competitive spirit in the likes of Sony, Aptina, Toshiba, etc. to get similar technology onto the market. I'd love to see bayer sensors disappear in the long run, in favor of something like either Foveon-esque designs, or perhaps dual-color array designs with color splitting (vs. color filtration, as filtration cuts out 60% or more of the light, greatly reducing overall Q.E., where as color splitting/microprisms preserve the vast majority of the light.)
I don't want Canon to use Sony sensors. I want Canon to become a major competitive player in the digital photography sensor world, to join the fight and help push image sensor technology farther, faster.
