Pentax SMC-A 28mm f2.8 Wide Angle in Lovely Condition

Pentax SMC-A 28mm f2.8 Wide Angle is ever so widely regarded as one of the best made by Pentax ever.

Here’s a lovely example for you, ready to go.

It’s always been one of my own personal favourites and will continue to be so forever!

Here’s some online blurb:

The SMC Pentax-A 28 mm f/2.8 is a compact, manual-focus wide-angle prime introduced in 1984 and produced until 1988, designed for full-frame K-mount film cameras. It shares the same optical formula as the second version of the Pentax-M 28/2.8 but adds an “A” setting on the aperture ring, enabling full program and shutter-priority automation on compatible Pentax bodies.

Optically, it features a 7-element/7-group design, Super Multi-Coating (SMC), and a 5-blade automatic diaphragm. It delivers a 75° diagonal field of view on full-frame (or ~55° on APS-C), focuses down to 30 cm, and offers 0.13× magnification. The lens uses a 49 mm filter thread, weighs just 170 g, and measures 63 × 36.5 mm.

It’s praised for its sharpness from f/5.6–f/11, neutral color rendering, and compact build, making it a great walkaround lens, in short, the A 28/2.8 is a practical and well-balanced wide-angle prime—ideal for film shooters or digital users seeking a lightweight, auto-aperture-capable lens with classic Pentax ergonomics and dependable performance.
