Lens Overview — Olympus 100mm f/2.8 E.Zuiko Auto T

The Olympus OM 100mm f/2.8 E.Zuiko Auto T is a manual focus prime lens built for the Olympus OM camera system. With a fixed focal length of 100mm and a maximum aperture of f/2.8, this lens sits firmly in telephoto prime territory, making it a compelling option for shooters who appreciate deliberate, hands-on focus control. It covers a full-frame image circle and mounts natively on any camera body with an Olympus OM mount, though adapters also open it up to a wide range of mirrorless and DSLR platforms.

At just 230g, it is notably lightweight for a telephoto prime, which contributes to a well-balanced, comfortable shooting experience over extended periods. The 49mm filter thread is a compact, widely supported size, keeping filter costs manageable. Image stabilization is not present, so shooters will want to factor in shutter speed or support when working in lower light.

The manual-only focus operation places full creative control in the photographer's hands, appealing to those who prefer a more tactile, deliberate approach to their craft. It is a lens with a focused, unambiguous specification set that rewards patient, skilled operators.

Key Features — Olympus 100mm f/2.8 E.Zuiko Auto T

100mm f/2.8 Prime: A fixed 100mm focal length with f/2.8 maximum aperture delivers strong subject separation and background compression typical of telephoto portrait and detail work.

Olympus OM Mount: Designed natively for the Olympus OM film SLR system, and widely adaptable to modern mirrorless and DSLR bodies via readily available OM mount adapters.

Full-Frame Coverage: Projects an image circle that covers full-frame sensors, making it compatible with both film bodies and modern full-frame digital cameras when adapted.

Manual Focus Only: All-manual focus operation gives the photographer direct, tactile control over focus without relying on autofocus motors or electronics.

Lightweight at 230g: Unusually light for a 100mm telephoto prime, making it comfortable to handhold and carry for extended shooting sessions.

49mm Filter Thread: A compact, widely supported filter thread size that keeps compatible filters affordable and easy to source.
