Canon’s 50mm f/1.2 Rangefinder Lens; A Legend In The Super-Fast
Realm Page 2  sorcadmin's picture A long focusing travel seems
to me to make focusing easier, and it certainly spreads out the
depth of field scale, which is marked for f/2.8, then
f/5.6-f/16. Two unmarked lines either side of the central f/1.2
index presumably correspond to f/2, and there is an IR focusing
mark--a red R and a dot--just to the left of the far-distance
depth of field mark. The equally-spaced diaphragm ring at the
front of the lens is click-stopped at f/1.2 and f/1.4 and
thereafter at whole-stop intervals (no half stops) to f/22; the
diaphragm has 11 blades.  User's eye view of the 50mm f/1.2

--always a sign of quality--and the huge depth of field scale.
All right. Enough background. What's it like? Well... First, I
tried it on a test chart using Kodak's Ektachrome EBX: not the
sharpest film in the world, but far from the least sharp, and
one that I know can deliver at
