Super compact pancake that in m4/3 crop terms this is 56mm f5.6. Lens comes with m4/3 adapter, but it can also be adapted to other mounts. First 2 photos are at f16 with flash. 1 is at 200iso and the other is at 800iso. Last picture is at f2.8, iso200, with flash. The F-stop marker dial on the front doesn't line up with numbers. Stopped down it sharper. I used  it wide open for video. Shows signs of use.
