Olympus's titanium electronic SLR — the OM-4Ti, multi-spot OTF metering, aperture-priority, OM mount, 1986.
The Olympus OM-4Ti is a 35mm film SLR from Olympus, the titanium-bodied version of the OM-4 in the professional tier of the OM system. Introduced in 1986, it refined the earlier OM-4 with a titanium top and base and improved flash capability. It represented the electronic, automatic-exposure flagship of the OM line, sitting alongside the mechanical OM-3Ti.
In specification terms, the OM-4Ti is a single-lens reflex for 35mm film using the Olympus OM mount, with an electronically-controlled focal-plane shutter. It offers aperture-priority automatic and manual exposure modes and uses the OM-4 metering system, providing centre-weighted and multi-spot metering that can average up to eight spot readings, plus highlight and shadow control. Its off-the-film (OTF) metering reads light during the exposure. Because exposure timing is electronic, the camera depends on battery power to operate its shutter and metering.
The OM-4Ti suits photographers who want automatic and manual exposure with detailed multi-spot control in a compact professional body, useful for landscape and travel work in high-contrast light. The multi-spot system and highlight/shadow buttons give precise placement of tones, while aperture-priority speeds up general shooting. It works across the full OM lens system with its improved dedicated flash support.
When buying used, remember this body is battery-dependent for both metering and the electronic shutter, so a dead or corroded battery will stop it; confirm it powers up and all modes respond. Some early OM-4 bodies had higher battery drain, later addressed, so check the battery does not run down quickly. Inspect and expect to replace the OM foam light seals and mirror-damper foam, test the shutter across speeds, examine the prism for haze or desilvering, and verify the multi-spot metering, film advance, rewind and focusing screen are all sound.
