My Noctilux looks like it will need a 3rd trip to Solms for adjustment. Before I send it again I want to be sure I am being realistic. This week I was in NYC for the Christmas cheer and I visited Leica NJ . I was able to go into the service department and watch the tests being performed on my 3 Summiluxes. Both my M8s backfocused....but this was adjusted for both the 35 and the 75 . I did some of the tests myself . We optimized the M8s for the 75 ..its a perfect 1/3 front to 2/3 back wide open ..the 35 was close enough same amount of DOF in front and behind the target. The 50 Summilux could not be adjusted due to the mount ..so its back to Solms for round 3. This one was irrefutable ..they put it on a piece of test equipment and it failed..out of tolerances. Ok thats the background ..the 50 Noctilux came back today ..the technician(Peter) has indicated that it front focuses at 1.0 but is on at 2.0 . My view is that may actually be within tolerances..for film. I plan to use the Noctilux at at 1.0 thru maybe 2.0 ..otherwise it will be the Summilux..so I think it should be dead on at 1.0 . The technician agrees but it is subjective. I think it has to go to Solms anyway as they messed up the focusing mount again..so it has a hitch at close focus. Am I shooting myself in the foot by asking for optimization at 1.0. I have tried David K s M8 and Noctilux at it is dead on at 1.0 ..so I know what its capable of.
