Has anyone used converted lenses on a 7d?

Is it possible to manually focus while recording?
Or do you have to move the aperture ring to f/22 to manually focus?

Sorry but I do not have the 7D. I could only explain how the 5D mark II first but 7D shares much of the same movie capabilities and limitations.

For 28-80 and 70-200, it is required to put the AF/MF switch to MF during movie capture in order to be able to manual focus the lens.

For the other 7 lenses in the N series, as well as all lenses in the 645 series, there is no need to set the lens' aperture ring to f/22 (or f/16 or f/32) during movie capture. There is no autofocus during movie capture anyway and since the lenses support full-time manual focus, no special steps are necessary. Just rotate the manual focus ring.
