Sample border crops - a lot of images

First crops from the left side (border slightly under the center)

Crops from the right side (border slightly under the center)

OK, conclusions:

  1. Best at f/5.6 and f/8, sharp in the corners as well
  2. Wide open sharp in the center, up to ~70% wide, suffers from CA and purple fringing.
  3. F stops and T stops do not correspond. At f/3.5 I had to lower the exposure by 2/3 of a stop in order to have the same exposure as with f/8 (with SS adjusted purely in relation to A). Lowering exposure also creates a better image at f/3.5.
  4. Have to very careful about bright lights in photos as they lower the contrast - and this is super wide so take care with photos with bright sky in them
  5. f/11 is also sharp
  6. f/16 acceptable for me
  7. f/22 - worse than f/3.5

Tried some video - not as bad barrel as I feared - it's in line with some kit lenses I have used previously If anything - people on the edges do not get their faces distorted as much - people seem to be used to GoPro and the like and don't mind some distortion. Also, due to crop all of the image is sharp even wide open.

Undistorting produces FoV much wider than 12mm, will have to experiment with this more.
