At 70mm, f/2.8 is already razor sharp. Diffraction starts from f/11 and increases at f16. Corners are good at 2.8 and excellent at f/4.

At 85mm, f/2.8 is a bit soft but at f/4 the quality is back on track. Corners look good already from the fastest aperture. Once again diffraction becomes noticeable from f/11.

At 105mm, the lens peaks at 2.8. The corners are good wide open but they become perfect at 5.6. Diffraction is more severe from f16.

stuff toy used for the sharpness test

At the minimum focus distance (0.5m at 70mm and 1m at 200mm), the performance remains at the highest level. It’s very sharp at 2.8 and the lens already peaks at f4.
