I assume that this is a mechanical thing, as a given Noctilux/Summilux is supposed to be interchangeable with all M's, including the M8. This would mean that either: 1. the lens flange-focal distance needs to be adjusted, and I can't see doing that yourself. I would guess it means taking the lens head off the helical and adjusting its spacing shim. 2. the lens flange-focal distance is correct, but the body flange to sensor distance needs to be adjusted. I suppose one could do this themselves, but I am guessing this would involve re-shimming the lens flange from the body, which would then force you to re-adjust the rangefinder arm. Not impossible at home, but the body is then matched to the one particular lens. Then would you hope that the adjusted body is good for all other lenses, or does the DOF take care of that? regards Vick -----Original Message----- From: lug-bounces+vick.ko=sympatico.ca@leica-users.org [mailto:lug-bounces+vick.ko=sympatico.ca@leica-users.org] On Behalf Of Robert Rose Sent: Friday, August 31, 2007 7:52 PM To: lug@leica-users.org; kapner@earthlink.net Subject: [Leica] Migrating to M8: What's Really Necessary? ... 4) In order to recalibrate lenses properly, do the technicians need to have my M6/7/8 bodies at hand? I have not heard of anyone sending back the M6 or M7; just the M8. I was very successful doing the focus adjustment myself. It is not so hard. I intend to post the process to the new Leica wiki. ...
