Fotodiox Pro PT67 - EOS Adapter for Pentax 67 Lens to Canon EOS EF/EF-S Mount (P67-EF-P) Review

The Fotodiox Pro PT67-EOS adapter bridges the gap between vintage Pentax 67 medium format lenses and modern Canon EF and EF-S mount cameras. At $37, it's an affordable entry point for shooters looking to experiment with classic glass on their DSLR or mirrorless body with an EF adapter. The Pentax 67 system is known for its large image circle and distinctive rendering, and this adapter unlocks those optics for creative portraiture, landscape, and video work where manual focus and aperture control are acceptable.

Keep in mind that this is a passive adapter with no electronic communication, so you'll lose autofocus, aperture control from the camera body, and EXIF data. The Pentax 67 lenses are also heavy and built for a larger format, which means vignetting or edge softness may occur depending on sensor size and lens choice. This adapter suits patient shooters comfortable with fully manual operation and willing to work within the optical limitations of adapting medium format glass.
