It's not very often that I get to photograph birds of prey in flight, or hold them — so when Fujifilm invited me to a pre-launch event for its new lens, I jumped at the opportunity. Today, on 4 September 2026, Fujifilm announced the new Fujinon XF 400mm F4.5 R LM OIS WR weather-sealed telephoto lens, designed for wildlife, birding and sports.A couple of days ago, I went hands-on with it to capture portraits and action shots of falcons, eagles and owls. Though the weather was far from ideal, with the skies pouring down on us as soon as the lovely ladies from U.K.-based Walks with Hawks brought out birds of prey, it was an enjoyable day out.I was given the 400mm lens and a Fujifilm X-H2S and I had a lot of fun with it. Here's everything I photographed with the kit.A long-reaching, lightweight tele lens

It's a super-telephoto APS-C lens with a 400mm focal length — that's equivalent to 609mm on a full frame sensor — and it's compatible with Fuji's X series of mirrorless cameras. With a maximum aperture of f/4.5, Fujifilm claims that it "delivers the highest optical performance in the XF lens lineup." That essentially means that it captures sharp photos.As the many letters in its name suggest, the XF 400mm F4.5 R LM OIS WR features up to 5.5 stops of optical image stabilization, and it's fully protected against dust, rain and can be used in temperatures as low as 14°F / -10°C. The lens' OIS enables you to shoot at slow shutter speeds, and I can confirm that it's weather-proof as I used it in the pouring rain.
