A nice fast optic for the 39mm screwmount rangefinder cameras from Voigtlander, Leica and Canon. It features an all-metal lens barrel construction and a 10-bladed aperture diaphragm which creates very pleasing out-of-focus highlights. Full rangefinder coupling is retained, and the aperture ring has click stops at half-stop intervals.
A standard L-mount is used for this lens, making it compatible with Voigtlander Bessa R & L cameras as well as classic cameras from Leica and Canon with the venerable 39mm screwmount design. If you desire to use this lens with Leica M, Voigtlander Bessa T or Konica Hexar RF cameras, use the adapter ring (catalog number 45BD205A). This lens retains rangefinder and viewfinder coupling with all the combinations.
