Pentax 35-70mm F/4 SMC A 2-Touch K Mount Manual Focus Lens Review

The Pentax 35-70mm F/4 SMC A is a legacy manual focus zoom designed for Pentax K-mount film and digital bodies. Part of Pentax's A-series lineup from the 1980s, it features the classic two-touch design with separate rings for zoom and focus, a layout that some shooters prefer for its tactile control. The constant f/4 aperture and SMC multi-coating deliver respectable image quality for its era, though expect softer corners wide open and typical vintage zoom compromises. At 58mm filter thread, it's a compact and lightweight option for those shooting Pentax DSLRs or film cameras who want an affordable walk-around zoom with a bit of character. This is a used bargain-grade example from KEH, so expect cosmetic wear and potentially some internal dust or slight haze, though it should remain functional for casual shooting or experimentation.
