Olympus Zuiko 100mm f/2 Manual Focus Lens for OM-Mount Review

The Olympus Zuiko 100mm f/2 is a legacy manual focus lens designed for the Olympus OM mount, a system that debuted in the 1970s and remains beloved among film shooters and vintage lens adapters. With a fast maximum aperture of f/2, it offers strong low-light capability and shallow depth-of-field control, characteristics that made it a favorite for portraiture and selective-focus work in its heyday. Today it's available primarily on the used market, where excellent-condition copies trade for around $860.

This lens is best suited for shooters who already own OM-mount film bodies or who plan to adapt it to modern mirrorless cameras. Adapted use requires manual focus and aperture control, which can be a draw for those seeking a deliberate, tactile shooting experience. The 100mm focal length falls into classic short-telephoto territory, useful for portraits, detail work, and street photography. Build quality on Zuiko lenses from this era is generally solid, with smooth focus rings and well-damped aperture mechanisms. For those invested in the OM ecosystem or exploring vintage glass, this lens delivers the optical formula and mechanical feel of a mature analog design.
