I checked most of my LTM lenses on a IIIf, M2 (via Leitz adapter) and Bessa-R. Results were the same with each camera. Looking straight on at the camera's front the Leitz lenses do indeed all bottom out at the 2 O'Clock position. My 85 & 135mm Nikkors do the same (with the 135 this leaves the tripod mount at 6 O'Clock where it belongs). My 15 and 35mm Cosina Voigtländer lenses stop at 11:58. Same with the 21mm Kobalux. So it seems the newer lenses, made with M mounting as a distinct possibility (Cosina makes LTM-to-M adapters, the Kobalux comes with one), aim to conform–though not exactly for some reason–to standard M lens behavior. - -Dave-
