It is made worse by a focus shift that occurs with this lens between f2 and f2.8. The focus shift causes a more pronounced back focus condition then at f1. The shift remains up to f5.6 or so but begins to be masked by the DOF. I have seen the same problem with my film M's but not to the extent of the M8. I have seen the same type of shift with the 50/1.4 Summilux but it generally stays in focus but barely. The APO 90/2 ASPH will also back focus. The hex adjustment to the rangefinder cam is not really a fix for this problem. That cam adjustment is the infinity adjustment for the Leica rangefinder. It does pull in the backfocus problem of the Noctilux but will also throw off the infinity focus of the long lenses. The best fix for these problems is to do what Tina did. Send Leica the lens and body. Len On Apr 1, 2007, at 12:51 PM, Frank Dernie wrote: > I have been going through the photographs take in the last week on > my newish M8.
