Asahi Pentax Spotmeter
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.

Frequently asked questions
What is an Asahi Pentax Spotmeter worth today?
Based on the only verified UK auction record, the Spotmeter sold for £88 hammer in 2025, so a working example with case is worth roughly that figure at saleroom level.
How much does a Pentax Spotmeter sell for at auction?
The available sales history shows a single hammer price of £88, which is the best current guide to its auction value; non-working or incomplete examples would be expected to sell for less.
What should I check before buying one?
Test the cell against a known meter for accurate readings, inspect the battery compartment for corrosion, and confirm the optical aiming window and needle movement are clean and responsive.
