The new Fujinon XF 400mm f/4.5 R LM OIS WR super-telephoto prime lens is designed to extend your reach and make shooting distant subjects easier, even in the most difficult conditions.
With a 35mm equivalent focal length of 609mm, this lens lets you get in nice and close without disturbing the scene – perfect for situations involving skittish birds and other wildlife, or when shooting fast-action sporting events from a safe distance.

Fujinon has already demonstrated its supremacy in this realm with earlier offerings such as the medium format GF 500mm f/5.6 R LM OIS WR and the APS-C format XF 500mm f/5.6 R LM OIS WR prime lenses.
Also designed for APS-C format mirrorless Fujifilm cameras, the new XF 400mm f/4.5 is compatible with optional XF1.4X TC WR and XF2X TC WR teleconverters, extending coverage to 560mm or 800mm – that’s 853mm and 1219mm respectively in 35mm equivalents – for capturing even more distant or subjects with clarity and ease.
Although the new 400mm prime lacks some of the versatility of a super-telephoto zoom, including the XF 150-600mm f/5.6-8 R LM OIS WR, it boasts a more generous constant f/4.5 maximum aperture, allowing for greater depth of field and the ability to isolate your subject more readily and dramatically.
And as a fixed focal length lens, the 400mm prime also offers superior edge-to-edge sharpness and faster tracking AF over options like the older XF 100-400mm zoom.
