Flexible Focal Length, Bright Design

The 100-400mm-equivalent zoom range provides flexibility for photographing distant wildlife, sports, and other subjects. Its constant f/2.8 maximum aperture supports shooting in available light while enabling shallow depth of field and selective focus.

The optical design incorporates low-dispersion and high-refractive-index glass elements to deliver clarity and accurate color reproduction. ZERO II (Zuiko Extra-low Reflection Optical) coating helps suppress flare and ghosting, maintaining contrast and color fidelity in strong lighting conditions.

Fast AF and Robust Sync IS

The lens features a fast, responsive autofocus system designed to track moving subjects, including birds, wildlife, and athletes. It supports continuous autofocus (C-AF) at continuous shooting speeds of up to 50 fps, making it suitable for high-speed burst photography.

For handheld shooting, the five-axis Sync IS system compensates for up to 7 stops of camera shake when paired with a compatible OM SYSTEM camera body. Without Sync IS, the lens itself provides approximately 5.5 stops of stabilization. The system also helps stabilize the electronic viewfinder image, making it easier to frame and compose distant subjects at longer focal lengths.

Unique Close-Up Focus and Advanced Optics

Despite its telephoto reach, the lens offers a minimum focusing distance of just 2.6′ throughout the zoom range. At 200mm, it achieves a maximum magnification of 0.25x, making it useful for capturing close-up details. The combination of optical stabilization and the bright f/2.8 aperture supports handheld shooting at close range.

When paired with compatible OM SYSTEM cameras, the lens also supports in-camera focus stacking for creating images with greater depth of field.

Outdoor-Ready Construction

Designed for demanding outdoor use, the lens combines a compact, lightweight build with extensive weather sealing. Its Micro Four Thirds design offers a more portable alternative to full-frame lenses covering a similar equivalent focal length range.

The lens measures just under 9″ long and weighs approximately 2.75 lb with the tripod adapter attached. Its internal focusing and zoom mechanisms maintain a consistent overall length, helping improve balance, handling, and weather protection.

IP53-rated weather sealing protects against dust and splashes, while supporting operation in temperatures as low as 14°F. A fluorine coating on the front element repels moisture, dirt, and oils, making the surface easier to clean.

Four function switches provide quick access to focus limiting, AF/MF selection, image stabilization, and the L-Fn/preset beep settings. Four L-Fn buttons offer additional convenient control directly on the lens.

Accessories and Teleconverter Compatibility

The included removable, rotating tripod adapter provides balanced mounting on a tripod or monopod. Its foot features an Arca-style dovetail and a 1/4″-20 tripod mount.

The included LH-82C Lens Hood features a sliding filter control window, allowing easier access to rotating filters such as polarizers and variable ND filters.

The lens is also compatible with optional MC-14 and MC-20 teleconverters, extending its effective focal length range:

• MC-14 1.4x Teleconverter: Provides a 140-560mm-equivalent range at f/4.
• MC-20 2x Teleconverter: Provides a 200-800mm-equivalent range at f/5.6.

These options extend the lens’s reach for wildlife, sports, and other distant subjects while maintaining the flexibility of the Micro Four Thirds system.
