The FUJIFILM XF 400mm f/4.5 R LM OIS WR Lens delivers serious super-telephoto reach in a lightweight, portable design built for photographers capturing distant and fast-moving subjects. Designed for FUJIFILM X-series cameras, its 400mm focal length provides a 600mm full-frame equivalent field of view, making it an excellent choice for wildlife, sports, aviation, outdoor action, and other situations where getting physically closer isn't possible.
A bright f/4.5 maximum aperture provides a strong balance between light-gathering capability, subject separation, and portability. Combined with the compressed perspective of the 400mm focal length, the lens can produce striking images with clearly isolated subjects and visually softened backgrounds while maintaining the reach needed for distant compositions.
For subjects that rarely stay still, the XF 400mm incorporates powerful autofocus performance designed to help photographers respond quickly to unpredictable action. Whether tracking wildlife across an open landscape or following athletes from the sidelines, its combination of extreme reach and responsive focusing makes it well suited for demanding telephoto photography.
Despite offering a 600mm-equivalent perspective, the lens maintains a compact, lightweight form factor designed with extended handheld shooting in mind. This portability makes it easier to carry into the field and work for longer periods without the bulk traditionally associated with extreme super-telephoto lenses.
Combining extensive reach, an f/4.5 aperture, powerful autofocus, optical image stabilization, and a weather-resistant design, the FUJIFILM XF 400mm f/4.5 R LM OIS WR Lens provides a versatile super-telephoto solution for photographers who need mobility without sacrificing the ability to capture distant subjects with impact and precision.
Lens Design
Weighing less than 3 lb and measuring only 9.4" in length, the lens design is optimized for convenient handheld use from the sidelines to mountain trails. 5.5 stops of optical image stabilization aid stability while shooting handheld by compensating for camera shake. In situations where extra stability is required, the tripod collar foot is Arca-type compatible for rapid mounting on tripods and monopods.
A combination of four extra-low dispersion, two super extra-low dispersion elements, and Super EBC coating preserves accurate colors, strong contrast, and sharp detail everywhere from sunny fields to snowy mountain peaks. The 21-element, 14-group optical design provides the clarity needed when shooting with high-resolution X-series sensors, while the rounded, 9-blade diaphragm delivers a beautifully soft bokeh that's further enhanced by the super telephoto compression.
Linear Motor Autofocus
Enhanced by the powerful subject detection algorithms in X-series cameras, the Linear Motor autofocus system delivers fast and accurate performance in near silence. Additionally, the lens features built-in focus presets designed to grant you greater control over your autofocus to capture fast-moving subjects.
Additional Details
- Full compatibility with the separately available 1.4x and 2x teleconverters boosts the reach to 560mm and 800mm, respectively, without a loss in image quality.
- Weather-resistant construction protects the lens against dust and moisture, enabling worry-free use in inclement conditions when used with a weather-resistant X-series camera body.
