Although with the 50mm originally mentioned there are only a few benefits, with wide angles these increase as the ability to place the rear elements closer to the plane is desirable and resultant in that legendary Leica quality. The smaller optical register also leads to more compact lenses, which is one of the major ergonomic benefits of the M system, the original comment was >I am hoping that Leica will soon introduce a new M 50 1.4 based on the >recently introduced R 50 1.4. > >Tom Shea which is pretty pointless unless one would like the M-series to become comparatively big and chunky. (please note I am not an Optical Lab Technician, although somewhere I do have an exact description of why optically speaking M-series lenses are purer, I just can't find the thing)
