Olympus's automatic 35-series rangefinder — 40mm f/1.7, programme auto exposure, leaf shutter, 1971.
The Olympus 35 DC was released in the early 1970s as an automatic-exposure model in the 35-series of fixed-lens rangefinder compacts. It was designed as a simpler, programme-automatic alternative to the manual-capable 35 SP, offering a fast lens in a compact metal body and remaining popular among users who want a straightforward but capable rangefinder.
The 35 DC is a fixed-lens 35mm coupled-rangefinder camera with a 40mm f/1.7 lens and a leaf shutter. Exposure is programme-automatic, set by a CdS meter, with the camera choosing shutter and aperture together rather than offering manual control. The meter was designed around a mercury cell of about 1.35 volts, so the voltage difference of modern replacement batteries should be considered for accurate metering.
In use the 35 DC suits a photographer who wants a fast-lens rangefinder that handles exposure automatically, making it easy to carry for street, travel and everyday photography. The coupled rangefinder gives accurate focusing while the automatic exposure keeps the camera quick to use, though the lack of a full manual mode means it depends on a working meter for correct exposure.
When buying, check the rangefinder patch contrast and alignment and confirm the leaf shutter operates at all speeds. Test the CdS meter, noting it was designed for a 1.35V mercury cell so an adapter or zinc-air substitute may be required, and because exposure is automatic a faulty meter limits usability. Inspect the lens for haze and fungus, check the light seals, and watch for sticky aperture blades and battery-door corrosion.
