I am hoping for an incremental evolutionary upgrade here. if its the 1.4 they are working with here, I agree with most here - keep it 1.4, better optics, better on AF (yes, it does tend to hunt more than I'd like).
Other than the 85mm v2, most of the primes lately have been geared towards video (the new wide primes are examples, both being 2.8, both having Is and both costing way more than their previous models.)
Hoping they intend to segment things like they do with the telephoto lenses - offer fast aperature, no IS (1.2, 1.4, 1.
- then the IS versions at f2.0-4).
Everyone likes to complain that there is no stills only camera (the good old bodies cost more because of video arguement), but damn, this is almost worse if the glass upgrades are gonna more more for video than stills.
