Olympus OM-1

{"overview":"The Olympus OM-1 is a 35mm single-lens reflex camera introduced in 1972, designed under Yoshihisa Maitani as the debut body of the Olympus OM system. As of today in 2026, most clean, working bodies sell for double-digit sums at saleroom level, and the value is strongly condition-led: examples with a seized shutter, corroded battery compartment or foam rot tend to sit at the bottom of that range, while tidy, tested bodies with a working meter are what push the price toward the upper end.","buying_guide":"The most common faults to inspect are degraded light-seal foam around the back door and mirror bumper, prism corrosion showing as a dark band across the viewfinder, and a non-working meter — the original circuit was designed for a 1.35V mercury PX625 cell, so a bodged voltage supply can throw exposure readings off. Check that all shutter speeds sound correct (especially the slow speeds), that the film advance is smooth, and that the mirror returns cleanly.
