==== Summary ====
The SMC Pentax 50mm f/1.4 is the original bayonet-mount iteration of Pentax’s legendary fast standard prime, produced from 1975 to 1977 as part of the K-series—the first generation of K-mount lenses following the M42 Takumar era. It shares the same 7-element, 6-group optical formula as its M42 predecessor, the SMC Takumar 50/1.4, but introduces a more modern mechanical design tailored for the new K-mount system. This version features Super Multi-Coating (SMC), an 8-blade automatic diaphragm, and stops down to f/22. It focuses as close as 45cm, delivers 0.15× magnification, and uses a 52mm filter thread. The lens measures 63 × 42mm, weighs 265g, and includes a metal barrel, engraved depth-of-field scale, and a smooth, long-throw focus ring that’s widely praised for its tactile precision. There’s no “A” setting on the aperture ring, so it’s best used in manual or aperture-priority modes on compatible bodies.
