The Color Heliar has all-metal lens barrel construction & a 10-bladed aperture diaphragm which creates pleasing out-of-focus highlights. Click stop aperture movement at half-stop intervals makes subtle adjustments in exposure or depth-of-field easy.

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 45BD209A). This lens retains rangefinder and viewfinder coupling with all combinations.
