Same Lens, New Branding. This is the same lens as the Olympus 40-150mm f/2.8 ED PRO but re-branded to reflect the transition from Olympus to OM System. As with the original model, the OM SYSTEM 40-150mm f/2.8 ED PRO is a pro-grade lens designed for fast-moving subjects.

Advanced Feature Set and Optics. The Dual Voice Coil motors drive the two separate focusing lens groups, giving you the extremely fast performance that’s required for capturing sports and wildlife. As part of the PRO series, this zoom distinguishes itself with a bright f/2.8 constant maximum aperture for consistent illumination throughout the zoom range to suit working in a variety of lighting conditions. Its optical design makes use of a series of aspherical and low dispersion glass elements to suppress chromatic and spherical aberrations for notable sharpness and clarity. A manual focus clutch permits quick switching between auto and manual focus, plus the programmable L-Fn button allows for lens-based control over shooting settings.

Robust and Reliable Construction. With 11 seals to keep out moisture and dust, the 40-150mm f2.8 PRO is ready to take on the elements. The premium metal lens body is portable despite its long range thanks in part to the internal zoom, which keeps the lens at 6.2". If you need more reach, this lens is compatible with both the MC-14 1.4x and MC-20 2x teleconverters.

Try it with These Micro 4/3 Cameras. This lens pairs with Micro 4/3-mount cameras with Micro 4/3 sensors, where it produces an 80-300mm equivalent focal range. Since it is designed with action in mind, it is a great choice for quick shooters like the Olympus OM-D E-M1 Mark III and the Panasonic GH6.
