Leica M 50/2 Dual Range Summicron Leica M 50/2 Dual Range Summicron The 50/2 Dual Range Summicron is one of the most interesting Leica M lenses with the closest rangefinder coupled focusing of any M lens. The removable 'eyes' provide parallax corrected viewing in the close focus range. The flat dovetail mounting base for the eyes gives the DR has a unique appearance among Leica lenses. A popular lens in the user market, many photogs consider the DR their sharpest lens. A 50 DR had the honor of having the highest resolution ever tested by the now sorely missed American photography magazine, Modern Photography, at over 100 lines per mm. Using it in the close up range can be confusing, and so the detailed explanation below. If you want to shoot closer than.7 meters with your M camera, the Dual Range Summicron remains your most convenient choice to this day.

There are a significant number of lenses produced from the 1940s through the 1970s that are. Here at Pro Photo Supply we offer a full listing of used inventory including cameras, lenses, tripods, lighting, and accessories on hand.

The eyes must be removed before mounting or dismounting the lens. Left pic shows lens mounted without 'eyes' close up attachment in normal focusing range, from infinity to one meter. The eyes will not mount in normal focusing range because the interlocking dovetail mount ball bearing can only be depressed in the close focusing range.

Right pic shows close-up of the eyes dovetail mount with the ball bearing. The classic chrome front caps are easy to lose, as well as dent or scratch. Use a modern plastic front cap in the field. Notice the eyes, there is some separation on the larger side, but it is still very usable.
