{{ :lens:pentax45mm6x7.png?350|}}
==== Summary ====
The SMC Pentax 67 / SMC Pentax-6x7 45mm f/4 is an ultra-wide-angle prime introduced in 1980 for the Pentax 6×7 medium format system, with a revised version released in 1989 under the Pentax 67 name. It delivers a diagonal field of view of 89°—roughly equivalent to a 24mm lens on 35mm film—making it one of the widest rectilinear lenses available for the system. It features a 9-element - 8-group optical design, Super Multi-Coating (SMC), and an 8-blade automatic diaphragm. The lens stops down to f/22, focuses as close as 37cm, and provides 0.17× magnification. It uses an 82mm filter thread, weighs 486g, and measures 91.5 × 57.5mm. It includes a rear gelatin filter holder, but no built-in hood. The lens has no “A” setting on the aperture ring, so it’s best used in manual or aperture-priority modes.\\
