Fujifilm has introduced a new fixed focal length lens tailored for photographers who specialize in capturing fast-moving subjects like sports or wildlife. The Fujifilm Fujinon XF400mmF4.5 R LM OIS WR is a 400mm lens with an f/4.5 aperture, which translates to a 600mm equivalent focal length on APS-C sensor cameras. This lens is designed to maintain a compact and lightweight form factor while offering high optical performance. It can be paired with Fujifilm’s 1.4x and 2x teleconverters, allowing photographers to extend the focal length up to approximately 1200mm, making it ideal for capturing distant subjects. The lens weighs 1.245 kg, with a length of about 24 cm and a diameter of 10.45 cm (excluding the lens hood). It is built to withstand harsh weather conditions, thanks to its weather-sealing. Internally, it features an advanced optical design with 21 lenses grouped into 14 elements, including four ED (Extra-low Dispersion) lenses and two Super ED lenses, which help reduce chromatic aberration and improve image clarity. The lens has a nine-blade diaphragm, allowing it to open up to f/4.5 and close down to f/22, with manual adjustment options that provide 15 different exposure settings. To aid in capturing fast-moving subjects, the lens includes optical stabilization, which works with the camera body’s sensor stabilization to offer up to 5.5 EV of stabilization, effectively reducing camera shake. It has a minimum focusing distance of 2.75 meters, allowing for a maximum magnification ratio of 0.16x. The focusing system uses a linear motor that is fast, precise, and quiet, making it well-suited for action photography. From an ergonomic standpoint, the lens includes customizable buttons, an AF mode switch, a focusing range limiter, and a manual diaphragm adjustment ring with an automatic position setting. It also features an adjustable tripod collar and the brand’s signature silver finish on long focal length lenses. The Fujifilm Fujinon XF400mm F4.5 R LM OIS WR will be available starting September 10, 2026, with a price tag of 2899 euros. This lens is expected to appeal to professional and advanced amateur photographers looking for a high-performance telephoto lens with versatile functionality and robust build quality.
