Rob,
It does seem odd. The more puzzling thing, to me at least, is that repair shops like DAG and others are able to make the adjustments to the lenses to make them work properly on the M8, as do other lenses. That suggests that there is still something not quite right on Leica's side of the build/calibration. All of my other lenses focus perfectly on my M8, but my Nocti has a backfocus problem. Seems that is the lens, not the camera body.
The focus shift issue is completely different, and I do not worry about that as much, knowing it exists and has for a long time. That is/has been a part of the Nocti design. The backfocus, or frontfocus issues are different, and not as much internal design related as calibration and mount design related.
Does anybody with a Nocti that has been "fixed" to focus properly on their M8 have back or front focus issues when they use that lens on a film body? Can you see the differences? If not, then why cannot Leica get the newly produced Noctiluxes to focus properly on the M8? If it does not impact the film bodies and how they focus, why not get things right on the M8?
Not looking for a argument or fight here....just wondering out loud, as the greatest number of "focus" complaints on many forums seem to be around a few lenses....the Nocti being one of the most mentioned.
