{{ :lens:pentax105mm6x7.png?350|}}
==== Summary ====
The SMC Pentax 67 / S-M-C Takumar 6×7 / Super Takumar 105mm f/2.4 is a legendary standard prime lens for the Pentax 6×7 medium format system, produced across three generations from 1969 to 2001. All versions share the same 6-element/5-group optical formula and a 9-blade automatic diaphragm, delivering a 46° diagonal field of view—roughly equivalent to a 55 mm lens on 35 mm film. This lens is renowned for its creamy bokeh, 3D rendering, and shallow depth-of-field, especially wide open at f/2.4—a uniquely fast aperture for medium format. It focuses down to 1.0m, uses a 67mm filter thread, and weighs between 590–628g, depending on the version. Dimensions are approximately 91.5 × 60mm, and it mounts via the Pentax 67 inner bayonet.\\
