The Canonet QL 17 GIII is the final, high-end version of Canon‘s famous Canonet compactrangefinder series of the 60s and 70s. It provides shutter-priority auto-exposure and parallaxcompensation with its 40mm f/1.7 lens. The lens is sharpest at f/4 – f/5.6 [1]. Its Copal leaf shutteroffers shutter speeds from 1/4 to 1/500, with X flash sync at any speed.

The meter uses a CdS cell mounted on the lens, just above the front element. It offers shutter-priority autoexposure, or unmetered manual mode. It uses a match-needle system in the viewfinder, showing apertures. There’s a smallfresnel lens in front of the CdS cell. When selecting a different shutter speed, you can see a ring with a series of perforations moving in front of the metering cell. This way, a smaller aperture gives less light on the cell. A simple, mechanical solution. Since the metering unit is placed within the filter thread, it compensates automatically for filters. Very handy.

It was designed to use the PX625 mercury battery, no longer available in the US. The circuitry in the camera holds up well against slightly higher voltages, so you can use a PX625A alkaline battery as a drop-in replacement, but you will find your exposures tend to be slightly off. Only the autoexposure system requires a battery, however. The mechanical shutter functions perfectly under manual settings with no battery whatsoever. Therefore, if you own a handheld light meter, you can use this camera without a battery
