Features:

Extreme 200-800mm Equivalent Super Telephoto Reach for Wildlife, Sports, and Aviation Photography

The OM SYSTEM M.Zuiko Digital ED 100-400mm f/5-6.3 IS II Lens delivers an extraordinary 200-800mm full-frame equivalent focal range, giving photographers the ability to capture distant subjects with incredible clarity and precision while maintaining a compact and travel-friendly setup. This massive zoom range makes the lens ideal for wildlife photography, birding, outdoor sports, motorsports, aviation photography, safari adventures, and even moon photography where getting physically closer to the subject is impossible. Unlike bulky full-frame telephoto systems that often require heavy support equipment, this Micro Four Thirds lens provides professional-level telephoto performance in a significantly smaller and lighter package. The ability to frame subjects from medium telephoto to extreme super telephoto focal lengths using a single lens also reduces lens changes in the field, helping photographers react faster to unpredictable moments while protecting the camera sensor from dust and debris.

Advanced Sync IS Stabilization for Sharper Handheld Telephoto Shooting

One of the most important upgrades in the IS II version is the addition of Sync IS compatibility, allowing the lens stabilization and compatible OM SYSTEM camera body stabilization to work together seamlessly for up to 7 stops of compensation. At ultra-telephoto focal lengths, even the smallest hand movement can introduce blur, but the advanced stabilization system dramatically improves handheld shooting performance, making it easier to capture sharp images and smoother video without relying heavily on tripods or monopods. This feature is especially valuable for wildlife photographers tracking moving animals, bird photographers shooting at dawn or dusk, and travel creators working in dynamic outdoor environments where carrying heavy support gear is impractical. The stabilization system also benefits handheld telephoto video recording by reducing unwanted shake and micro-vibrations that often occur at longer focal lengths.

Lightweight and Portable Design Compared to Full-Frame Telephoto Systems

Despite offering an 800mm equivalent focal length, the OM SYSTEM 100-400mm IS II remains remarkably compact and lightweight at approximately 1125g, making it substantially easier to carry than traditional full-frame super telephoto lenses. This portability gives photographers greater mobility during long hikes, wildlife expeditions, travel assignments, and outdoor events where minimizing gear weight becomes critical. Instead of carrying massive 500mm or 600mm prime lenses that require specialized bags and heavy-duty tripods, users can achieve similar telephoto reach in a much more manageable setup that supports handheld shooting for extended periods. The smaller form factor also makes the lens more discreet and easier to transport during flights and travel photography assignments while still delivering professional-grade telephoto results.

Premium Optical Construction for Superior Sharpness and Clarity

The lens features an advanced optical design consisting of 21 elements in 15 groups, including 4 ED elements, 2 Super HR elements, and 2 HR elements engineered to reduce chromatic aberration, distortion, ghosting, and flare across the entire zoom range. This sophisticated optical formula helps maintain high levels of sharpness, contrast, and color accuracy even at extreme focal lengths where image quality can often degrade in lesser telephoto zooms. The incorporation of ZERO coating further improves performance by minimizing reflections and flare when shooting in challenging lighting situations such as sunrise, sunset, or backlit wildlife scenes. As a result, photographers can achieve cleaner images with improved micro-contrast and more accurate color reproduction, helping subjects appear more detailed and lifelike.

Professional Weather Sealing Built for Harsh Outdoor Environments

The OM SYSTEM 100-400mm IS II is designed specifically for photographers who work outdoors in unpredictable conditions. Featuring IPX1-rated weather sealing along with dustproof and splashproof construction, the lens is built to withstand rain, humid environments, dusty trails, and cold weather conditions when paired with compatible OM SYSTEM camera bodies. This rugged durability gives photographers the confidence to continue shooting during challenging wildlife expeditions, outdoor sports events, and remote landscape adventures without constantly worrying about environmental exposure damaging their equipment. The fluorine-coated front element also repels water, oil, fingerprints, and dirt, helping maintain image quality while reducing the need for frequent cleaning during field use.

Fast and Quiet MSC Autofocus Optimized for Wildlife and Video

The integrated MSC (Movie & Still Compatible) autofocus system delivers fast, accurate, and nearly silent focusing performance, making the lens highly effective for both photography and video applications. Fast-moving wildlife, birds in flight, and sports action demand responsive autofocus performance, and the MSC system helps maintain subject tracking while reducing focus hunting. The quiet focusing operation is especially valuable for video recording where autofocus noise can interfere with captured audio. Smooth focusing transitions also contribute to more professional-looking cinematic footage when shooting handheld telephoto video content.

Teleconverter Compatibility for Up to 1600mm Equivalent Reach

For photographers who need even more reach, the lens is fully compatible with OM SYSTEM MC-14 and MC-20 teleconverters. With the MC-20 attached, the lens reaches an astonishing 1600mm full-frame equivalent focal length, unlocking extreme super telephoto capabilities rarely achievable in such a portable system. This expanded reach is particularly useful for bird photography, wildlife observation, lunar photography, and distant sports coverage where subjects remain extremely far away. Even with added teleconverters, the system remains considerably lighter and more manageable than comparable full-frame alternatives, preserving the mobility advantages of the Micro Four Thirds ecosystem.

Enhanced Handheld Freedom for Travel and Outdoor Photography

Traditional ultra-telephoto photography often requires large tripods, monopods, and extensive support gear, but the OM SYSTEM 100-400mm IS II changes that experience by making handheld super telephoto photography far more accessible. The combination of compact size, lightweight construction, and powerful image stabilization allows photographers to move freely through nature reserves, hiking trails, sporting venues, and travel destinations without being slowed down by oversized equipment. This flexibility improves reaction time and shooting spontaneity, helping photographers capture fleeting moments that may otherwise be missed while setting up support systems.

Excellent Tele-Macro Performance for Small Subjects and Fine Details

Beyond long-distance shooting, the lens also provides impressive tele-macro capabilities with a minimum focusing distance of just 1.3 meters and up to 0.57x full-frame equivalent magnification. This allows photographers to capture small wildlife subjects, insects, textures, flowers, and intricate natural details while maintaining a comfortable shooting distance that minimizes subject disturbance. The ability to combine strong telephoto compression with close focusing performance adds another layer of versatility, making the lens useful for far more than traditional wildlife photography alone.

Intuitive Professional Controls for Faster Operation in the Field

The lens includes multiple external controls designed to improve operational speed and efficiency during demanding shoots. Dedicated switches for autofocus/manual focus, image stabilization, focus limiting, and zoom locking allow photographers to make quick adjustments without navigating camera menus. The removable tripod collar improves balance when using support systems and provides smoother transitions between landscape and portrait orientations. These practical design elements enhance usability for professionals and serious enthusiasts who need rapid adjustments while tracking unpredictable subjects in fast-moving environments.

Designed Specifically for the Micro Four Thirds System

Unlike adapted or oversized telephoto lenses, the OM SYSTEM 100-400mm IS II is purpose-built for the Micro Four Thirds platform, maximizing the system’s advantages in portability, stabilization, and telephoto reach efficiency. The 2x crop factor effectively doubles focal length equivalence without increasing the lens size, allowing photographers to achieve extreme telephoto perspectives in a more compact package than nearly any competing interchangeable lens system. This design philosophy makes the lens an exceptional choice for photographers who prioritize mobility, flexibility, and real-world usability without sacrificing professional image quality.
