Description — Olympus 12-100mm f/4 IS PRO
The Olympus M.Zuiko Digital ED 12-100mm f/4 IS PRO is a Zoom lens designed for the Micro Four Thirds mirrorless camera system. It spans a focal length range of 12mm to 100mm, with a constant maximum aperture of f/4 maintained across the full zoom range, making exposure behavior predictable whether you're at the wide or telephoto end. The lens supports both autofocus and manual focus, giving shooters full control depending on the situation.
A key feature is the hybrid image stabilization system, which pairs in-lens stabilization with compatible in-body image stabilization (IBIS) for additional steadiness during handheld work. The 72mm filter thread accommodates a wide variety of common filter accessories, and the lens tips the scale at 561g — a meaningful but manageable weight for the focal range on offer. Mounted via the Micro Four Thirds lens mount, it integrates directly with the MFT ecosystem of mirrorless bodies, making it a strong single-lens option for photographers who value range and consistency in a compact mirrorless kit.
