K&F Concept Nikon AI to Pentax K Adapter

The K&F Nikon AI to Pentax K Camera Mount Adapter with Optic Glass allows Nikon F-mount lenses to be used on Pentax K-mount DSLR cameras, supporting infinity focus and featuring a durable, high-precision design.

This adapter provides Pentax DSLR users the flexibility to mount Nikon F-mount lenses, including AI, AIS, and other manual-focus types, onto Pentax K-mount camera bodies. Made from precision-engineered brass and aluminum, it ensures a stable connection, minimizing wear and maintaining alignment between lens and camera.

A built-in optical element allows for infinity focus, making it ideal for landscape, astrophotography, and general shooting. Fully manual operation gives photographers control over focus and aperture directly on the lens. Compatible with a wide range of Pentax K-series cameras, it is recommended to use a tripod for heavy lenses to maintain balance and protect the camera mount.
