Minolta Rokkor W MC 28/2

sorry for crap picture, it's taken with cheap android phone

really nice lens. 2 shots below at wide open. closest distance ( marked 0.3 m)

As we might know, some wide lenses including 28mm isn't good at infinity. this lens is good enough. corners looks not better than SK Curtagon 28/4. but it's sharp enough.

 it's perfect for street shot
