This lens was "the" standard lens sold with Yashica SLR cameras. It can
be found for low prices, it's
very decent. Wide open it's fine for F 1.9, there is a hint of shaded
upper edges, but it's perfectly usable. Stopped down it's
sharp. The lens has some
close focussing capablities. It is relatively small and
lightweight, particularly for a F 1.9 lens. A nice lens which offers
one usable stop more than a standard lens.
