Reverse mounted lens at f16 which I think hurt the sharpness. Next time I try this I will only stop down to f5.6 or f8 on my 50 1.4.
This is from a Panasonic TC-P50ST50. The horizontal lines are part of their anti-glare filter. I'm not sure if the diagonal lines are as well or it they're used for some other purpose, maybe structural?
This was taken with a solid white jpeg displayed on screen. Next time I'll try to get it sharper.
