The Voigtlander Color-Skopar 21mm f/4.0 Lens is a sharp wide angle for 39mm screw mount cameras from Voigtlander, Leica and Canon. With the attached focus assister you go from minimum distance to infinity in less than ninety degrees of rotation. Apertures are selected with the click-stop diaphragm. A standard M39 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 screw mount design. If you desire to use this lens with Leica M, Voigtlander Bessa T or Konica Hexar RF cameras, use the optional adapter ring (catalog number 45BD205A).
