Asahi Pentax-6x7 45mm f/4 Lens Hood
This is a rectangular metal hood intended for the various iterations of the Pentax 67 45mm f/4 lens with 82mm filter threads. Same shape as the PH-SB lens hood, but an earlier production not marked as such. A shallow hood, it may be suitable for lenses with similar focal lengths and the same front diameter. Clip-in type mounting. In excellent cosmetic condition, with only minor surface wear.
