DescriptionOlympus 40-150mm f4 ED

The Olympus M.Zuiko PRO ED 40-150mm f/4 is a Micro Four Thirds telephoto zoom lens designed for mirrorless camera bodies with the Micro Four Thirds mount. It spans a focal range of 40mm to 150mm and maintains a constant maximum aperture of f/4 throughout, so your exposure settings remain stable no matter where you are in the zoom range. The lens weighs just 382g, keeping things manageable for photographers on the move.

A 62mm filter thread means compatibility with a broad range of standard filter accessories is straightforward. Both auto and manual focus are supported, offering flexibility across different shooting scenarios. Image stabilization is not included in the lens itself, so stabilization-dependent shooting will rely on the camera body's capabilities.

With its native MFT mount, the lens integrates directly with compatible Micro Four Thirds mirrorless systems, offering a clean and reliable connection without adapters.
