Pentax SMC 100mm f2.8

The SMC Pentax‑A 100mm f/2.8 Macro is a high‑quality macro prime lens for Pentax cameras with K‑mount, designed for full‑frame (35mm) use. It was one of Pentax’s first 1:1 macro lenses, allowing life‑size reproduction of subjects.

With a bright f/2.8 aperture it handles low‑light situations well; stopping down to f/4‑f/8 yields exceptional sharpness and detail. The optical design consists of 7 elements in 7 groups, 8 aperture blades, and a 58mm filter thread. The minimum focusing distance is about 31 cm. 

Thanks to its SMC (Super Multi Coating), you’ll see vibrant colors, good contrast, and minimal flare. The metal housing and precise manual focus make it a favorite among macro photographers, portrait shooters, and those who appreciate fine detail.

This lens comes with both front and rear lens caps, as well as the original Pentax leather case.

The serial number of this lens is 4074106.
Aperture works smoothly, and the glass is clear.
