I was taking a video with my D90 recently and was thinking about a big drawback to using DSLR for serious video. I haven't seen this problem discussed yet, so I thought I'd start a thread here about it (even knowing there are many video-DSLR haters around).
Manual zoom rings can be pretty fluid when you're careful, but no matter how careful you are you get some vibration when you adjust zoom during filming. Do you think we'll see the camera able to control zoom in the future? I'd like to see a remote that can control both focus and zoom during filming, so that the camera isn't shaken when you adjust them.
The extra noise from another motor wouldn't bother me since I don't usually use the in-camera sound. (I'll have to review my Zoom H4n field recorder here at some point. The short version is that I love it!)
Do you think in the future Nikon will release new versions of their lenses with a way for the camera to control zoom as well as focus?
If so, will it start out like their autofocus screw system did or do you think they would (or should) go straight to putting in a built-in motor dedicated to zoom?
