The Fujifilm XF 400mm F4.5 R LM OIS WR is a premium super-telephoto prime lens designed for Fujifilm X Series mirrorless cameras. Delivering an equivalent focal length of 609mm in full-frame terms, this lens is ideal for wildlife, birding, sports, and action photography. Combining exceptional reach with a relatively lightweight design, it offers professional-grade performance for photographers who need speed, precision, and portability.
Exceptional Super-Telephoto Reach
With a 400mm focal length (609mm equivalent), the lens brings distant subjects remarkably close while maintaining outstanding detail and clarity. Its narrow angle of view makes it perfect for capturing wildlife, field sports, aircraft, and other faraway subjects with impressive impact.
Bright F4.5 Aperture Performance
The constant F4.5 maximum aperture balances light-gathering capability with portability. It enables faster shutter speeds for freezing action and delivers attractive background separation, helping subjects stand out against smoothly blurred backgrounds.
Advanced Optical Design
Engineered with high-quality ED and Super ED elements, the lens effectively minimises chromatic aberrations, distortion, and flare. The result is sharp, high-contrast images with accurate colour reproduction throughout the frame.
Fast Linear Motor Autofocus
The powerful Linear Motor (LM) autofocus system provides quick, silent, and highly accurate focusing. This makes the XF 400mm F4.5 particularly effective for tracking fast-moving wildlife and athletes.
Reliable Optical Image Stabilisation
Built-in Optical Image Stabilisation (OIS) helps reduce camera shake when shooting handheld at extreme focal lengths. This allows photographers to capture sharper images and smoother video footage in challenging conditions.
Weather-Resistant Construction
The robust WR (Weather Resistant) design features extensive sealing against dust, moisture, and low temperatures. It is built to perform confidently in demanding outdoor environments.
