M39 Lens Mount to Canon RF Camera Mount

Traditional lenses, many looks

I purchased the M39 to Canon RF adapter to use a Russian 40mm uncoated lens (that has been modified to western focal lengths) with my Canon RF. I also purchased a Voigtlander 28mm M39 mount lens for my Bernback Leica. I'm enjoying using both lenses with my Canon and Leica. The quality is fantastic and the fit is perfect with no light leaks. Measurements are accurate. A wonderful product to expand your use of classic screw mount lenses with modern Canon RF mount bodies.
