Pentax 70mm f/2.4 SMC PENTAX-DA Limited Autofocus APS-C Lens for K-Mount, Black Review

The Pentax 70mm f/2.4 SMC PENTAX-DA Limited is a compact portrait-length prime designed for Pentax APS-C K-mount bodies, delivering a 107mm full-frame equivalent field of view. Part of the well-regarded Limited series, this lens emphasizes portability and discreet handling without sacrificing optical performance. The f/2.4 maximum aperture is fast enough for subject separation and low-light work, though not quite as wide as competing f/1.8 or f/2 options. The SMC (Super Multi-Coating) treatment aims to minimize flare and ghosting while preserving contrast.

This lens is built with a metal barrel and a notably slim profile, making it a natural fit for street photography, environmental portraiture, and travel. The Limited line has long appealed to Pentax loyalists who value tactile quality and understated design. At around 160 USD on the used market, it offers an accessible entry into the Limited family for APS-C shooters looking to expand their prime lens collection. The autofocus motor is driven by the camera body, so speed will depend on your K-mount model.
