I recently worked a wedding as a second shooter. I mostly worked with the photographer's Canon, but I had the opportunity to shoot with my Em5 ii during the dancing. I was using the Oly 12-40 with the Fl600r flash bounced off the ceiling. It worked fine for the opening dances with the bride, groom, mother and father. But then they turned the lights out and the camera couldn't find focus. It hunted and hunted. I finally figured to switch to manual focus. That let me get some decent shots, but even so they were often soft. What are other people's experience with this rig - or any mft camera- in the darkness of a dance floor? Any tips on how to get consistent shots? Am I missing something? My auto assist lamp is turned on, but it didn't seem effective. Thanks for any thoughts.
