Yup. I'm on record as saying I'd pay $3-4K for a 5DIII in crop factor form and no ISO/image quality penalty. I have a 7D and a 5DIII and the 7D sits unused, the 5D is that much better.
HA! I knew you people were out there.
Don't get me wrong, the 7D is a capable camera, I think it gets beat up a bit too much on the forums. It's just that the 5D is better. I'm really hoping that the 7DII is like a 5DIII w/ a 1.6x TC that doesn't take a stop of light and doesn't drop the image quality. That would be worth a lot to anyone who does wildlife, especially birds.
But I think you realize the madness of Canon were they to offer it. Even if they could pull off a 'crop 5D3' with the same IQ, to do so would damage their FF body sales and the sale of their superteles. People could simply do more (on the long end) with less gear. Canon probably does not want that.
Further, I'm not sure a crop sensor can actually beat a relatively contemporary FF sensor like the 5D3 or 6D.
So the question becomes, how close does the 7D2 IQ have to be to that of the 6D or 5D3 to have you opt for that instead of FF?
