Here's a shot from today...partial defish with Fisheye-Hemi. I noticed that this lens focus breathes a LOT, so you lose more FOV at closer focus distances than at the infinity hard stop. Also learned to stick to f/11 and larger apertures. Beyond f/11, diffraction takes a HUGE hit in sharpness...moreso than in most other lenses. At f/8 (this shot), it's very sharp...f/11 is still quite good, f/16 is quite soft across the frame.
