This is a very luminous lens. Wide open it's fine for F 1.4, there is
upper edges and a little bit of overcast, but it's usable. Stopped down
sharp and clear. The lens has limited
close focussing capablities. It is relatively small, particularly for a
F 1.4 lens. It has less yellow tint than the rest of the 1.4 and 1.2
lenses, especially the Tomioka lenses. A nice lens which offers two
usable stop more than a standard lens.
