The Canon Canonet QL19 GIII is a compact 35mm rangefinder camera with a 45mm f1.9 lens and a fully mechanical shutter system, with the option of shutter-priority autoexposure. These take a 625-type battery (which is included) but the only thing you'll lose if you run without a battery is metering: all the speeds are mechanical and aperture can be adjusted manually. This Canonet is in excellent cosmetic condition, with only minor wear; shutter speeds and metering are accurate. Good rangefinder, new light seals, and clean lens. A nice camera in nice shape.
