Hi, am trying out videography with my 7D.
So far been shooting in manual focus, and using my left hand to adjust the focus ring of my 50mm lens to keep sight of my video subjects.
It's kinda awkward and uncomfortable.
I read about manual focus rings:
1. How do you exactly install / use one?
2. Do you need to have a full video rig to mount it properly? Or can you just handhold and adjust the manual focus in a more comfortable manner?
