The Minolta Auto Meter IIIF is a handheld light meter designed for both incident and reflected light measurement, used by photographers and cinematographers to determine exposure independently of an in-camera meter. It was sold as a working tool rather than a camera body, intended for studio and location use.

Sales data for the Auto Meter IIIF is thin: a single UK auction hammer result from March 2023 saw one sell for £62, so any sense of what the meter is worth today rests on that lone wholesale data point. With only one record, there is no meaningful range or median to cite, and the price a clean, working example sells for in 2026 could vary materially with condition and accessories at saleroom level.
