I could dig them out, but they're ugly and boring. I wasn't sure
about the focusing after I bought the camera, so I put it on a tripod
at about 30 or 40 degrees off the wall, and photographed a series of
lines one inch apart at various distances with various lenses. I did
this with a Noctilux, the 75/1.4 and the 90/2, and with a .72 M6, a
.85 M6 and the Hexar. The .85 did best, while the .72 and the Hexar
were about equal but showed a little bit bigger spread (I did 5
shots, refocusing each time) with the Noctilux and the 75. The 90/2
showed a bigger spread with the Hexar, so that's not a good
combination. The 75 showed enough accuracy for me to trust it.
I don't do this sort of testing much, but once in a while it's
necessary so that you can know what the limitations of the equipment
are and you can feel confident using it.
I'll see if I can scan and post a real photo that I took wide open at
close distance in the next day or so.
