Olympus Zuiko 75-150mm F/4 2-Touch OM Mount Manual Focus Lens Review

The Olympus Zuiko 75-150mm F/4 2-Touch is a legacy manual focus telephoto zoom designed for the OM mount system, a platform that flourished in the 1970s and 1980s. With its two-touch design (separate rings for zoom and focus), it represents the era's approach to precision lens control. The constant F/4 aperture throughout the zoom range was a practical choice for its time, and the 49mm filter thread keeps accessories compact.

This lens appeals primarily to film shooters still using OM-mount bodies or to digital users who adapt vintage glass for creative effect. Build quality on Zuiko lenses from this period is generally solid, though manual focus and the absence of modern coatings mean it won't match contemporary autofocus telephotos in speed or contrast. At this price point, it's an affordable entry into telephoto shooting for the OM system, though condition varies widely in the used market.
