LAUNCHED 1975 GUIDE PRICE £100-130* Automation and an electronic shutter arrived with the OM-2, using a switch on the top-plate to offer manual or aperture priority modes. The OM-2 was the first camera to feature off-the-film (OTF) metering, in which the exposure sensor measures light reflected from the film. Variations in the light during long exposures are measured and compensated for during the actual exposure. With an Olympus flashgun fitted, the meter’s sensor also controls flash exposure for through-thelens (TTL) flash automation.
