Bring Distant Action Closer  

FUJINON XF400mmF4.5 R LM OIS WR lens gives image makers the reach needed to frame distant wildlife, birds, and outdoor sports with clarity and control. Offering a 35mm-equivalent focal length of 609mm, it brings hard-to-access subjects closer without forcing photographers to compromise their position or disturb the scene. This reach is especially valuable when subjects move unpredictably or cannot be approached, whether on the sidelines, in open landscapes, or deep in the field. The result is a super-telephoto prime that helps users isolate decisive moments, compress perspective dramatically, and create strong subject separation from afar. 

Ready To Go Further 

Super-telephoto performance shouldn’t compromise mobility. Weighing just 1245g (2.74lbs) and measuring 23.95cm (9.4 inches) in length, FUJINON XF400mmF4.5 R LM OIS WR lens is designed to stay agile in situations where photographers need to move, react, and keep working for extended periods. From long outdoor events to wildlife trails and remote locations, its refined design makes handheld use more practical and less tiring than traditional long-lens setups. For photographers who value reach but also need a lens they will willingly carry and use all day, this balance of size and performance becomes a meaningful creative advantage. 

Stay with The Moment  

When photographing distant wildlife or fast outdoor action, any delay means a missed moment. FUJINON XF400mmF4.5 R LM OIS WR lens uses a high-speed linear autofocus motor to deliver fast, quiet, and accurate focusing performance perfectly suited to unpredictable subjects. Focus presets – allowing you pre-select specific focusing ranges – further help reduce reaction time, giving photographers a more direct way to respond when action unfolds quickly. Whether tracking movement across a field or following wildlife that changes direction without warning, the lens is built to keep up.

Handhold with Confidence 

Super-telephoto photography demands stability in situations where tripods and monopods are often impractical or cumbersome. FUJINON XF400mmF4.5 R LM OIS WR features up to 5.5 stops of Optical Image Stabilization to help reduce the effects of camera shake during handheld use. This added stability supports photographers working in the field, on the sidelines, or in changing outdoor conditions where freedom of movement matters. By making handheld super-telephoto image making more dependable, the lens helps users stay responsive and confident when working at distance.  

Built for Clear, Detailed Results  

FUJINON XF400mmF4.5 R LM OIS WR lens is engineered to deliver the high level of optical performance serious wildlife and sports photographers expect from a dedicated super-telephoto prime. Its optical design uses four ED and two Super ED elements to help control aberrations and preserve sharp detail, rich contrast, and accurate color across demanding conditions. Ghosting and flare are also controlled thanks to Super EBC lens coatings. This matters most when photographing distant subjects where fine texture, edge definition, and clarity are critical to the final image. The result is a lens built to produce clean, high-quality files that hold up under close inspection. 

Built for the Outdoors   

Wildlife and outdoor action photography rarely happen in controlled conditions. FUJINON XF400mmF4.5 R LM OIS WR lens is built with weather-resistant construction so photographers can keep working when conditions become wet, dusty, cold, or unpredictable. When paired with a weather-resistant FUJIFILM X Series camera body, it becomes a dependable tool for the environments where many of the most compelling outdoor images are made. This durability helps users stay focused on timing and composition rather than worrying about the elements. 

Extend Your Possibilities   

Some subjects always seem just beyond reach. FUJINON XF400mmF4.5 R LM OIS WR lens is compatible with optional XF1.4X TC WR and XF2X TC WR teleconverters, giving photographers a simple way to extend coverage for even more distant wildlife and outdoor subjects. This added flexibility is especially useful for photographers who regularly work in expansive environments where getting physically closer is not possible. By supporting 
system growth without changing shooting style, teleconverter compatibility makes the lens an even more versatile long-term tool for dedicated super-telephoto users.
