Launched as a screw-mount lens in 1949, and in M bayonet mount in 1956, the 35mm F/3.5 Summaron is a beautifully made lens and, although it can’t compete in performance with later Leitz 35s, it is still capable of producing very pleasing results.

My 1958 copy is in pretty nice condition cosmetically, and is the M3 version with ‘goggles’. The viewfinder on the Leica M3 only has frame lines for 50mm, 90mm and 135mm lenses, so this viewfinder attachment corrects the field of view to match that of the lens and allow accurate framing.
