Re: [Leica] Does the 90 F4 Elmar C lens work on the M6?

[John Collier <jbcollier@home.com>]

Yes, there may be a problem. It is a great lens but was designed for the
Leitz/Minolta CL. The CL lenses had a different, steeper lens focusing cam
than normal M and CLE lenses. The CL camera, which does not have to focus
f1.0 lenses, has a simpler, shorter based rangefinder mechanism. The
cameras' rangefinder is fine tuned by adjusting the length of the roller arm
which means that it can be in a slightly different position horizontally
from one camera to another. The short ending to the long story is that quite
often the M and CLE camera's rangefinder will not couple to a CL lens
correctly. Point the combination at a point at least two miles away and, if
everything lines up OK at infinity, it should be fine. If it does couple
correctly, bear in mind that it may not work so well with your next body. Do
not forget there is a M mount 90/4 that is also not very expensive .
