This is a Minolta Auto III light meter, a professional-quality tool. It measures incident light (the light falling on a subject). It takes a bit more judgement than a reflected light meter, but it isn't fooled by subjects darker or lighter than normal. It uses one AA battery. The meter operates correctly.  I compared its readings with another Minolta meter and with a Gossen Luna-Pro to verify its accuracy. The meter reads ambient light; it does not measure flash.

The meter has one quirk you should be aware of. When the meter is turned on, it defaults to ISO 100 and EV (not f/stops). A quick push of the EV/F stop button restores the reading in f-stops; the up/down arrow buttons set the ISO to whatever speed film you are using. I wish the meter would "remember" the settings when it was turned off, but it doesn't. The meter is not broken; this is the way Minolta designed it to function.

There are options such as a spot meter attachment available on eBay for this meter.

I am selling the cameras and photo equipment I have collected over the past fifty years. They have not been film tested but appear to function correctly (film winds on, shutter fires, f/stops change, focus works). Shutter speeds sound approximately correct to my ear but speeds have not been electronically tested. I have disclosed any problems that I am aware of and have tried to act like a fussy sharp-eyed buyer in evaluating the cameras and lenses. The items have been stored in an air-conditioned non-smoking home. Remember that many of these items are classics, over forty years old, and inevitably will show some wear and signs of age.
