Fujifilm Debuts XF400mm: Fujifilm’s Latest Lens Innovation

Introducing the Fujinon XF400mm f/4.5 R LM OIS WR, their newest super-telephoto prime lens that offers an unparalleled focal length of 609mm, equating to substantial range for APS-C sensor cameras. This lens promises exceptional optical performance, standing out as a powerhouse within the XF collection.

The 609mm equivalent focal length reveals a crop factor slightly above the typical 1.5x for APS-C sensors, from 1.52 to 1.53x—a subtlety that adds to its unique charm.

Fujifilm’s Design for Speed

Perfect for capturing distant, fast-moving subjects, this lens is ideal for wildlife and motorsports photography. With compatibility for Fujifilm‘s 1.4x and 2x teleconverters, you can extend your reach to a maximum focal length of 800mm, or a full-frame equivalent of 1,219mm.

Joining Fujifilm’s range alongside the 200mm f/2 and the 500mm f/5.6, it comprehensively covers a full-frame equivalent of 305mm to approximately 762mm. This new option enhances the range for photographers.

A Look Inside

The lens boasts an intricate optical design of 21 elements in 14 groups, featuring two Super ED and four ED elements to reduce chromatic aberration and enhance resolution. Its aperture ranges from f/4.5 to f/22 with a nine-bladed diaphragm, delivering superb image quality. Fujifilm introduces these impressive specifications to the lens.

Engineered for Stability

Measuring 104.5mm at its widest point and 239mm in length, and weighing 1,245 grams, the XF400mm maintains balanced handling thanks to its centralized center of gravity. Dust and weather-resistant seals at 20 points fortify the lens against harsh conditions, down to temperatures of -10 degrees Celsius.

Additional features include a focus preset function, a focus control button up front, a focus limiter, and an optical stabilization system offering up to 5.5 stops of compensation. These advanced features are included to improve user experience.
