   At f/2 and f/2.8 my Summilux 50 ASPH focuses a touch behind at 1.5 m. Wide open it is spot on. Is this focus shift, or is my rangefinder off?

   That is classic focus shift; the lens is calibrated wide open. Try the same test on a tripod at 1 m and 3 m.

   Mine does the same between f/2 and f/4. I focus a hair in front and stop worrying.

   Right, and Leica will not fix it because nothing is broken. If it is behind wide open too, send the camera, not the lens.
