Pentax smc Pentax-FA 77mm f/1.8 Limited - Pentax K Mount

Part of the renowned Limited series, this compact prime is highly regarded for its distinctive rendering and portrait capabilities. The optical design prioritises character and bokeh over clinical sharpness, making it a favourite for film and digital K-mount users. It features a built-in retractable lens hood and a high-quality aluminium barrel, maintaining a traditional feel despite its modern autofocus capabilities. Check the mechanical aperture ring for positive clicks and ensure the screw-drive autofocus engages correctly. As an older design, internal dust can sometimes be present, so inspect the glass under bright light. SDS verifies the alignment of the retractable hood and tests the diaphragm blades for oil or lag, which can affect exposure accuracy on this model.
