For Canon to grow their camera division, they either has to buy an MF maker, build an MF camera or have a new generation sensor that will keep sales going for another 5 - 7 years on the top-end. Each one of my theories has it's pros and cons. Different levels of possibilities. Camera sales are flat, if not dropping all over the place. They have to figure out a way to grow.
Really, DSLRs at every level are so good. I still think that APS-C sensors will eventually be replaced by FF. You can get a NEW FF camera for $1600. That was UNHEARD of just three years ago. I think the 70D was the beginning of this revolution and it's bigger brothers are going to replace the typical FF sensor. Sensor may be the same size. But the tech will be a whole new generation.
I have two reasons why I think Canon's next big MP camera is going to be something super-incredible:
* Filter Down Technology. The tech in the big MP camera will be so amazing, it's technology will eventually filter down to the lower-end cameras over time. Like what happened with the 1DX. While the 1DX is pretty darn amazing, it's sensor isn't. It's all the other tech in that camera that make it so amazing. But it won't stay the leader for very long. It's an evolution camera.
* Zeiss 55mm Lens. Have you seen this lens? It's freakin' crazy the resolution this thing has. The only camera that will even remotely takes advantage of it is the Nikon D800. But that one camera is nowhere near enough to warrant the research, design and production of this lens. You gotta know Canon filled them in on something. The new Zeiss lens is a WHOLE OTHER LEVEL to any other FF lens out there. From what I've seen, images from it are MF quality. Damn impressive. As big as the 55mm lens is, you gotta know a 90mm or 130mm lens is going to be monstrous in it's size. Beefier EF mount you say?
The beefier EF mount for use in Cine Lenses? Possibly if the new cam is going to be a kick-ass video machine as well. Those Cine lenses are HUGE. When I was chatting with a Canon rep at a local camera store, we put a Cine Lens on a 1DX. Yes, the image was beautiful. But the lens size was totally impractical for the camera to use with stills.
I think 2014 is going to be a very exciting year for Canon. I can't wait!
