Mamiya 645 to Nikon 1 Adapter

This mount adapter connects classic Mamiya 645 lenses to Nikon 1-Series mirrorless cameras such as the V1 and J1. Its all-metal brass and stainless steel construction provides a secure, stable connection without adding bulk. The design uses the central portion of the lens image circle to deliver edge-to-edge sharpness on the smaller sensor. Photographers can extend the life of their medium-format glass on a compact digital platform.

Suits legacy lens owners; not for autofocus needs

The adapter suits photographers who already own Mamiya 645 lenses and want manual-focus creativity on a Nikon 1 body. It appeals to users who value the unique rendering of larger-format optics on a smaller sensor. Buyers who require electronic aperture control, autofocus communication or EXIF data transfer should look elsewhere. The purely mechanical design means all exposure settings must be managed manually.

Infinity focus mechanical adapter

The critical specification is the mechanical infinity focus capability that allows accurate focusing at all distances. Precision machining maintains the correct flange distance so Mamiya 645 lenses reach true infinity on the Nikon 1 mount. The brass and stainless steel build prevents play between lens and body for consistent results. No electrical contacts are present, so the camera operates without lens metadata.
