Voigtlander

Voigtlander VM  Adapter II for Sony E Mount Cameras allows you to mount a VM mount (Leica bayonet) lens to a Sony E mount camera, such a NEX-3, NEX-5, NEX-5N, or NEX-7. Adapter does not provide electronic communication between the camera and the lens - works with manual focus and exposure.

The Voigtlander Micro Four Thirds to M Lens Mount Adapter allows the use of rangefinder M mount lenses with any Micro Four Thirds Digital Camera body. The adapter is compact in size, light in weight, and fully compatible with all Voigtlander, Leica, and other M-series lens manufacturer optics....
