Here's a short I did a little while using the Olympus E-M1 II.
It was shot using the internal 4K codec, and using the Olympus Pro lenses. I used a mix of the primes, the 17, 25 and 45mm mostly and they look really beautiful wide open. I used the SLR Magic ND filters to make sure I had the right exposure to keep me near to wide open most of the time. I also used the 12-100 Zoom for a lot of the content on the water.
All shot handheld, using IS mode 1 and 2.
Graded and edited using DaVinci Resolve, I left the bottom right corner UNGRADED so you can see what the Olympus FLAT (now called LOG) profile looks like before and after, and gives you a great idea of how the much you can push the image around in the grade.
