Testing out some shots with my epl-7 and DJI Spark... For the super telephoto shots I used an old manual focaus Vivitar 100-300mm F/5 giving me an effective focal length of 600mm. The lens performed admirably while still, but panning was a shaky mess. The IBIS on the EPL-7 really struggles during panning even with the Panasonic 12-60mm. I guess I'll just have to save up for the EM1ii and 80-150 f/2.8! I'm also trying out Davinci Resolve's recommended export settings for youtube.
