Bridge for Pentax K Lenses

The Thinkstar PK-FX adapter connects Pentax K mount lenses to Fujifilm X series camera bodies including X-Pro1, X-E1 and X-M1 models. It allows photographers to continue using existing Pentax glass on a different mirrorless system without changing lenses.

Replaces Native Mount Limitation

This adapter solves the incompatibility between Pentax K bayonet lenses and Fujifilm X mount cameras. The upgrade is worthwhile when a photographer already owns Pentax K lenses and wants to access Fujifilm X body features such as electronic viewfinders or film simulations without buying new native lenses.

Manual Focus Integration

The adapter provides a mechanical connection with no electronic contacts so aperture and focus remain fully manual on the lens. It requires lenses with an aperture ring and adds no autofocus or EXIF transmission. The compact design keeps the combined unit balanced for tripod or handheld use.
