SPECIFICATIONS

It has 7 multicoated elements in 6 groups.

It extends 1.8" (46mm) from the camera lens flange and is 2.5" (64mm) around

It is heavy: 11.1 oz (315g).

Full click stops are at f/1.4 and f/2. Half stop clicks are from f/2 through f/16. This is weird, but typical for Minolta.

It has a 55mm filter thread.

Focus is to 1.75' or 0.5m.

It's made entirely of metal.

There is very little barrel distortion

It's sharp at all apertures. It's a little less contrasty due to some veiling at f/1.4 caused by some residual spherical aberration, however there is still a very sharp image inside the veiling, unlike the Nikkor which is soft all over at f/1.4

Color balance is neutral.

Focus is a dream: the waffle-pattern rubber has perfect grip, and the smooth and precise focus helicoids respond to focus with one fingertip.
