There are two 50/4 macro lenses, the K and the M-versions.

 

Acc. to Bojidar, both can do 1:2 (mag. 0,5x).

I own the SMC M42 version and it a very sharp lens at close-up/macro distances, virtually as good my new Sigma 70mm macro. But at infinity, though it is still sharp in the center, the corners are soft and so I would not recommend it for infinity shooting. Hardly surprising since, to my knowledge, it does not contain any floating elements.
