silver92b - DAG is reputable, if he says he can get the M240 back to baseline, and then adjust any problematic lenses back to baseline as well, then might as well give it a try. Just because Germany uses a machine for "perfect" alignment, doesn't mean someone cannot do it by hand. I was just shocked to hear because of what Leica told me.
Also I forgot about this occasion in the early M240 days:
My experience seems to back up Leica's claim. I was in Japan, and had with me only my Noctilux. It was to spec, but my M240 had developed a problem (read on to know why I know it's my M240). They (Leica Germany) said that IF I wanted to, Ginza Leica could fix my problem, but ultimately I would have to send the camera and lens to Germany. It took Leica Ginza a while, while I paged through magazines, and when the item was "adjusted" I asked the guy what had been done, and he said that he adjusted the lens to work with the body (this could have been a language barrier issue). However, when I got back home, the Noctilux no longer worked with my other M240 cameras (this is an extreme case because the Noctilux is 0.95). It along with my M240 had to be sent to Germany. Leica also mentioned they'd do this for me, with the understanding that it was a quick fix as not to ruin my vacation.
Usually I would have brought more lenses and bodies with me, but in this case I just wanted to bring my Noctilux and M240 as I was planning on buying a Sony (don't remember if it was the RX1 or A7 at that time) camera for quick snaps and I had heard that Japan sold them cheaper (I found out while I was their that the "cheaper priced" Sony cameras I wanted were Japanese menu only cameras).
