This is an early-70s vintage 35mm camera with a Rokkor 38mm fixed lens. It’s a point-and-shoot with automatic-only metered exposure, no manual shutter or aperture control. You focus by guessing the distance and turning the ring on the lens barrel, and the viewfinder shows the meter reading inside. Some Hi-Matic cameras were rangefinders, but this one is a zone focus. It’s a decent daylight camera and I bought it used for cheap, mainly because it’s very classy-looking and it fits in my pocket. If you’ve seen the beautiful Fujifilm X-100 digital camera, you might’ve noticed that Fuji and other companies are trying to emulate the classy looks of cameras such as this.
