The Minolta Flash Meter III is a slightly old-school digital light meter for flash and existing light photography. Set your ISO and shutter speed on the handy mechanical dials, and the LCD screen will display the correct F stop or EI number. Includes incident light dome, reflected light disc, strap, instructions, and case. In very good cosmetic condition, with some surface wear. The rotation action of the sensor unit is smooth, but somewhat stiff: this shouldn't affect everyday use (not much reason to be rotating it around in most day-to-day situations) but it's worth noting. Batteries included.
