Used Voigtlander Mount Adapter for M39 to M-Mount | 28-90mm | U8

The Voigtländer M39 to M-Mount Adapter (28-90mm) is a precision mechanical ring that lets photographers mount 39mm screw-mount rangefinder lenses onto Leica M-mount cameras. By adding the exact 1mm spacing needed to match the M-mount flange focal distance, it ensures accurate rangefinder coupling and reliable infinity focus. Its bayonet flange features a specific keying notch that automatically brings up the 28mm and 90mm framelines in compatible M-series viewfinders. This makes it the ideal pairing for lenses like the Voigtländer Ultron 28mm f/1.9 when shooting on a Leica M6 or digital M body. Made from solid, finely machined metal, the adapter provides a wobble-free connection that turns screw-mount glass into quick-change bayonet lenses.
