I'm shooting a series of interviews solo - and using my EM-1 as a main camera, with a simple GoPro as a second angle. I've found the hard way that at 29mins, the EM-1 just ... stops. Is there a camera compatible with my existing lenses that can record for an hour or more, and isn't crazy expensive? (this would be it's only purpose) - or a way I can make the EM-1 record longer? Seems that total recording time capacity is a little discussed topic, so it's tough to find details on.
