Compañero, piensa bien lo que vas a a hacer, que "unos cardan la lana, y otros se llevan la fama"...
Canon EOS 350D with Helios-44-2 2/58
A comparison with my Carl Zeiss Planar 1.7/50mm
100% crops at f/4, both lenses focused at infinity:
Helios-44-2 2/58mm
Carl Zeiss Planar 1.7/50mm
There doesn't seem to be much to choose between the lenses if the resolution difference due to the different focal lengths (58mm vs. 50mm) is ignored. The Helios might have a slight edge, though.
