Does the focus stay put as you zoom? I would think this is a bigger issue for video.


it doesn't


The subject doesn't stay perfectly in focus while zooming. However the focus change is not large, and I can operate the zoom with one hand and focus ring with the other...I'm talented that way. :-)

...but, that doesn't leave me another hand to compensate exposure for an f-ratio change.

The 5D2 actually does a nice job with video, even at higher iso....I just try to keep it as low as possible to avoid noise problems in post.
