Voigtlander 20mm F3.5 Color Skopar SL II

Manufacturer description: The 20mm f3.5 Color Skopar SL II is the new addition to the Voigtlander SLR fit lenses, similar to the old Nikkor 20mm f3.5 AI lens. Available in Canon EF and Nikon AI-s mount, with the added attraction of an in lens CPU like a P Nikkor for electronic metering coupling and full multi mode operation with AF and Digital SLR cameras.On a DSLR with an APS C sized sensor, it behaves as a wide angle (equivalent to 30mm in 35mm terms) lens when taking the field of view crop into account.
