A distinctly fast and flexible lens, the M.Zuiko Digital ED 50-200mm f/2.8 IS PRO, from OM SYSTEM, is a 100-400mm-equivalent telephoto zoom that mixes a bright , stable design with a robust, weather-sealed, and lightweight construction. Built for wildlife, sports, and general adventure applications, this lens is at home in the outdoors and able to keep up with the fastest-moving subjects.
Flexible Focal Length, Bright Design
Covering a useful range for photographing wildlife and sports subjects, the 100-400mm-equivalent zoom range is backed by a fast constant f/2.8 maximum aperture for tremendous versatility in a variety of shooting conditions.![]()
- Truly unique 100-400mm-equivalent zoom range with a constant f/2.8 maximum aperture in a portable, hand-holdable design offers more flexibility when photographing distant moving subjects.
- Bright f/2.8 maximum aperture suits working in available lighting conditions and enables making shallow depth of field, selective focus images.
- Optical design includes a series of low dispersion and high refractive index glass elements for impressive clarity and color accuracy.
- ZERO II (Zuiko Extra-low Reflection Optical) coating suppresses flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions.
Fast AF and Robust Sync IS![]()
- Especially quick and responsive autofocus system suits working with quick-moving subjects and distant targets, including birds, wildlife, and sports scenes.
- The focusing system supports C-AF at continuous shooting speeds up to 50 fps, too, to keep up with fast burst shooting needs.

- Offering greater freedom for handheld shooting, a 5-axis Sync IS system compensates for up to 7 stops of camera shake for sharper images when working at slower shutter speeds. This Sync IS setting requires a compatible OM SYSTEM body; if used without Sync IS, the lens itself compensates for approximately 5.5 stops of camera shake.
- Beyond the sharper resulting images, this IS system also provides a more stable EVF image for easier framing and composing at great distances and with longer focal length positions.
Unique Close-Up Focus and Advanced Optics![]()
Despite its association with distant subjects, this 50-200mm lens also excels with close-up scenes thanks to a minimum focusing distance of 2.6' throughout the entire zoom range. This offers a maximum magnification of 0.25x at the 200mm position and the combination of Sync IS and a bright f/2.8 design greatly benefit handheld shooting at close range. Also, when used with compatible OM SYSTEM cameras, this lens supports in-camera focus stacking functions.
Outdoor-Ready Construction
Built for use in a wide variety of climates, this zoom is distinguished by its impressively compact and lightweight design as well as thorough weather sealing for safe use outdoors.![]()
- Emphasizing the benefits of Micro Four Thirds, this lens remains particularly sleek and lightweight compared to the full-frame lenses covering a similar equivalent focal length range.
- This lens measures just under 9" long and weighs about 2.75 lb with the tripod adapter attached.
- Internal focus and zoom design maintains a consistent overall length for better weather sealing, improved balance, and more intuitive handling.

- IP53-rated weather sealing guards against dust and splashes, as well as temperatures down to 14°F, for confident use in harsh weather conditions.
- Front element features a protective fluorine coating that repels moisture, dirt, and oils, and is easier to clean than an uncoated surface.
- Four separate function switches (focus limit, AF/MF, IS On/Off, and L-Fn/Preset Beep On/Off) and four L-Fn buttons allow for quick and intuitive on-lens settings adjustment.
Accessories![]()
- A removable, rotating tripod adapter in included to facilitate easier and balanced attachment to a tripod or monopod. The foot has a Arca-style dovetail along with a bottom 1/4"-20 tripod mount.
- Included LH-82C Lens Hood features a sliding filter control window, which provides easier access to the front of the lens to adjust rotating filters, like polarizers or variable NDs.
- Compatible with optional MC-14 and MC-20 teleconverters which increase the effective focal length by 1.4x and 2x, respectively. When the MC-14 is attached, the equivalent effective focal length will be 140-560mm f/4 and, with the MC-20 attached, the equivalent effective zoom range will be 200-800mm f/5.6.
