A one-of-a-kind, high-image-quality, large-aperture, super-telephoto zoom lens, covering a focal range equivalent to 100-400mm F2.8 on its own and up to 800mm F5.6 when used with a 2x teleconverter. This large-aperture, super-telephoto zoom lens covers a focal range equivalent to 100-400mm at an aperture of F2.8 throughout the entire zoom range. With a 2x teleconverter, it reaches a maximum focal range equivalent to 800mm F5.6. The bright maximum aperture allows for shooting with a high shutter speed and reduced ISO sensitivity, making it ideal for capturing birds and wildlife active in low-light situations such as early morning and dusk. The wide focal range also enables a wide range of expression in landscape photography, making this single lens suitable for a wide range of photographic scenes. This lens features a luxurious lens design with 21 elements in 13 groups, including a large-diameter EDA lens and two Super ED lenses. Despite its large F2.8 aperture throughout the entire zoom range, it suppresses color bleeding and flare, delivering excellent resolution all the way to the edges of the frame. The newly developed ZERO (Zuiko Extra Low Reflection Optical) Coating II also suppresses ghosting and flare, delivering clear, sharp images even in challenging shooting environments, such as backlit conditions. The inner zoom system minimizes shifts in the center of gravity during zooming, enabling stable framing and comfortable extended shooting. High-speed, high-precision focusing supports continuous shooting with AF tracking at up to 50 frames per second. Furthermore, this lens offers excellent close-up capabilities with a minimum focusing distance of 0.78 meters across the entire zoom range. The maximum magnification is equivalent to 0.5x, and telemacro photography at 1:1 is possible when using a 2x teleconverter. This lens is ideal for nature macro photography, such as capturing insects that tend to flee when approached. In addition, it supports the depth stacking feature unique to OM SYSTEM cameras.
Supports 5-axis sync image stabilization with up to 7.0 stops of compensation for smooth handheld shooting. Supports 5-axis sync image stabilization, working in conjunction with the camera's in-body image stabilization. Thanks to a high-precision gyro sensor and optimized image stabilization algorithm, it boasts a world-leading 7.0-stop compensation step at 400mm equivalent. Furthermore, the image stabilization function not only reduces camera shake during shooting, but also proves effective when framing a shot, ensuring the subject remains within the frame. Keeping the subject within the frame can be particularly challenging when shooting handheld at ultra-telephoto ranges, but 5-axis sync image stabilization stabilizes the viewfinder image. This makes handheld ultra-telephoto shooting a breeze. Despite being a large-aperture super-telephoto zoom lens, it weighs only approximately 1075g (excluding the tripod mount), making it easy to carry. This compact and lightweight system allows for greater mobility and greater mobility, allowing you to move freely in search of your subject.
High reliability and operability support shooting in harsh natural environments: With IP53 dust and water resistance and a low-temperature resistance design that can withstand temperatures as low as -10°C, it can be used safely even in harsh environments. The front lens element is coated with fluorine, so even if water droplets or dirt get on the lens surface, it can be easily wiped away, allowing you to resume shooting immediately. Even in rapidly changing weather conditions, you can focus on shooting without worrying about your equipment getting wet. The lens housing is coated with a heat-shielding coating. Compared to standard black coatings, it reflects sunlight's infrared rays more efficiently, reducing internal lens temperature increases even when used in the blazing sun, ensuring stable optical performance. It also features the following functions to enable ease of use, allowing you to concentrate on your photography. Rubber zoom/focus rings ensure smooth, high-quality operation; a focus limit switch allows for quick focusing based on the subject's distance; a focus switch allows for instantaneous AF/MF switching; a preset focus function that memorizes and instantly recalls any focus position; four L-Fn buttons that can be assigned to various functions and are within natural reach for both vertical and horizontal shooting without taking your eye off the viewfinder. The lens hood also features an operation window that allows for the rotation of a circular polarizing filter, which is frequently used in landscape photography. The tip of the hood is made of rubber to prevent scratches. The tripod collar can be attached and detached even with a lens attached to the camera. The lens foot is designed for a comfortable grip during transport and is compatible with Arca-Swiss clamps.
