Konica's IIIA — fixed-lens 35mm rangefinder, mechanical leaf shutter, life-size finder, manual exposure, 1958.
The Konica IIIA, from 1958, was a fixed-lens 35mm rangefinder in Konica's well-built III series of the late 1950s. It refined the earlier Konica III, notably with a life-size combined viewfinder and rangefinder, and was among the more advanced Japanese rangefinders of its day.
This is a 35mm coupled-rangefinder camera with a fixed Hexanon lens and a mechanical leaf shutter, using a double-stroke film advance lever on the front of the body. Exposure is manual, with the photographer setting aperture and shutter speed; the mechanical shutter fires without a battery. Metering is external or by separate meter depending on use.
The IIIA suits general, street and travel photography for users who value a solidly built manual rangefinder with a bright, large finder. Its all-mechanical operation avoids battery dependence entirely, though the front-mounted advance lever and 1950s ergonomics take familiarisation.
On inspection, check the lens for haze and fungus, and confirm the leaf shutter and aperture blades operate cleanly across speeds. Verify the double-stroke advance and rewind feel correct, and check rangefinder patch contrast and alignment given the combined life-size finder. Replace perished light seals as needed.
