f/2 This lens is a little soft with a fair amount of spherical aberration. Thereby causing
the lens to look soft and hazy, with a fair bit of chromatic aberration.
f/2.8: Sharpens up nicely with good contrast and less chromatic aberrations.
f/3.5: Sharper yet, with more contrast and almost no chromatic aberrations.
f/4: Sharper yet.
f/8: Sharper yet.

A little bit of vignetting at f/2 which quickly clears off at f/2.8 and almost gone by f/3.5

The blur is poor and distracting.

This is a large 50mm f/2 lens that is really well built and simple to use. However, it suffers from a fair bit of spherical aberration when shot wide open. It’s a sharp lens and if you want an f/2 lens then you can’t go wrong. Also, for a little more money you can buy a lighter, smaller, less distorted lens that has better optics–the Nikon 50mm f/1.8 E lens.

If you stumble upon one for cheap you can’t go wrong. They are fun to play with but I wouldn’t go out of my way to find one.
