New Guy here..
I have been filming concerts with my gh2 and 20mm lens (panasonic) . It has been great, but last week I used the auto focus function instead of the manual focus. There were some positives and some negatives,
Positive: I could focus on and off a subject and different objects while I was recording.
Negative: The auto focus is a little too slow or would be focusing on something I wasn't trying to focus on..
So my problem, its hard to focus during the shot with manual focus, either my fingers get in the way or I shake the camera, but I do need shots of musicians out of focus and then coming into focus during a shot.. Auto focus does this great but its not great 100% of the time..
I know it sounds confusing, but any suggestions?
