I could really use..
external power zoom and focus controls on lenses, for video.
F-mount obviously has focus interfaces, but can it be smoothly controlled?
And, does F-mount include zoom control from the body, for any future lens that would support power zoom?
We really need an external power zoom/focus control interfaces, to place on stabilizers away from the body, so we don't have to touch the body.
I predict the D5 will include even more video features including external lens controls, while introducing a corresponding 24-70 F/2.8 VR lens with power zoom.
This will get rid of all clunky follow-focus controls.
We'll have to wait 4 more years, though..
