The FUJIFILM XF 400mm f/4.5 R LM OIS WR Lens is a lightweight super-telephoto prime designed for wildlife, bird, sports, and outdoor photography. Made for FUJIFILM X-series mirrorless cameras, this powerful 400mm f/4.5 lens delivers a 600mm full-frame equivalent focal length, giving photographers exceptional reach for capturing distant subjects while remaining compact enough for handheld shooting.
Lightweight 600mm-Equivalent Super-Telephoto Reach
Despite its impressive telephoto performance, the FUJIFILM XF 400mm f/4.5 weighs less than 3 lb and measures approximately 9.4" long. Its portable design makes it an excellent choice for photographers who need serious reach without carrying an oversized super-telephoto lens.
Built-in 5.5-stop optical image stabilization (OIS) helps reduce the effects of camera shake, providing greater stability when photographing wildlife, birds, sporting events, and other distant subjects handheld. For tripod and monopod use, the included tripod collar features an Arca-type compatible foot for convenient mounting.
Advanced Optical Performance
The XF 400mm f/4.5 features a sophisticated 21-element, 14-group optical design incorporating four extra-low dispersion (ED) elements and two super extra-low dispersion elements. These specialized elements help minimize chromatic aberrations while maintaining excellent sharpness, contrast, and color accuracy across the image.
FUJIFILM's Super EBC coating further enhances image quality by reducing flare and ghosting in challenging lighting conditions. A rounded 9-blade diaphragm, combined with the natural compression of the super-telephoto focal length, creates smooth background blur and strong subject separation.
Fast Linear Motor Autofocus
A high-performance Linear Motor autofocus system provides fast, precise, and nearly silent focusing for still photography and video. When paired with the advanced subject-detection capabilities of compatible FUJIFILM X-series cameras, the XF 400mm f/4.5 is well suited for tracking birds, wildlife, athletes, and other fast-moving subjects.
Built-in focus preset controls provide additional flexibility, allowing photographers to quickly adapt the lens's focusing behavior to demanding shooting situations.
Weather-Resistant Construction
Designed for serious outdoor photography, the XF 400mm f/4.5 R LM OIS WR features weather-resistant construction to help protect against dust and moisture. When paired with a weather-resistant FUJIFILM X-series camera, it's ready for challenging environments ranging from rainy sidelines to dusty trails and snowy landscapes.
FUJIFILM Teleconverter Compatibility
For photographers who need even greater reach, the XF 400mm f/4.5 is compatible with FUJIFILM's optional 1.4x and 2x teleconverters. The 1.4x teleconverter extends the focal length to 560mm, while the 2x teleconverter provides an impressive 800mm focal length, making this lens an especially versatile option for wildlife and bird photography.
