The Visoflex housing was the attempt by Leitz to broaden the appeal and deployment of the Leica camera. As a reflex housing is was a brilliant solution: an accurate 100% viewing area and a very clear screen were unusual in those days. As a tool, it was less successful: slow, cumbersome and with a load of adapter rings and other necessary equipment, it was not easy to use. Yet, it allowed the Leica rangefinder user an additional series of lenses from 65 mm to 560 mm.

The 65mm Elmar lens had the classical 4/3 design. The first version Wetzlar design. Second version is a Midland redesign.

The performance of the first and second versions are visibly different. At medium apertures the second version has a much enhanced contrast with clear definition of fine detail. Over the years the Elmar-V was a consistent seller with some 400 units per year to a total of close to 9000. The combination of a dedicated lens for macro-photography and the Visoflex unit definitely filled a gap in the rangefinder system when compared to reflex systems: the viewfinder system was not supportive for close-up pictures. Currently Leica-M users can use the excellent Macro-Elmar-M 90mm that covers the same ground.
