Notes on Zeiss Distagon T* 28mm f/2.0 ZF & Nikkor 45mm f/2.8 P

Zeiss Distagon T* 28mm f/2.0 ZF
f/2.8 Center 80% of frame is very sharp.
Slight peripheral softness.

f/4.0 as sharp as any Nikkor can get.

f/8.0 sets the perfect golden standard.

Nikkor 45mm f/2.8 P
60% of the center frame is already rendered quite sharply.
However the extreme left and right frame is soft.
Peripheral softness is visible.

Strangely the four corners are distinctively soft.
Whereas the center of the frame is very sharp.
Acceptable portraits at f/4.0, maybe.
Must position subject in center of the frame.

This lens is almost totally primed.
The entire frame is extremely sharp.
Large improvement on the peripheral sharpness over f/2.8.
Good enough for landscape photography.
Near Zeiss performance.
