Pentax SMC Pentax-F 35-80mm f/4-5.6 - Pentax KAF Mount

The SMC Pentax-F 35-80mm f/4-5.6 was one of the earliest autofocus zoom lenses for the Pentax K-mount. It features a distinctive grey finish and a compact, primarily plastic barrel. Designed for 35mm film SLRs, it remains compatible with modern Pentax digital SLRs. It uses the camera's internal screw-drive motor for autofocus and provides a useful focal range for everyday snapshots and landscapes. Second-hand examples should be checked for the integrity of the plastic mount and the stability of the extending barrel. SDS inspects for common issues such as internal haze or fungal growth between elements. The autofocus coupling should be clean and engage firmly. Ensure the zoom ring does not feel overly loose, a common sign of heavy use in these earlier consumer-grade zooms.
