The Asahi Pentax Spotmeter is a handheld exposure meter designed to read reflected light from a narrow angle, allowing precise measurement of small areas within a scene. It was produced by Asahi Optical Co. as part of the wider Pentax accessory range to support 35mm SLR photography.

Hammer prices at UK auction are thin for this model, with a single recorded sale at £88 in July 2025 setting the only reliable reference point for what the Spotmeter is currently worth. With just one data point in the saleroom, today's market value sits around the high-double-digit range, and what the meter sells for in practice will hinge heavily on whether the cell still reads accurately and the case and strap are present.
