Fujifilm has announced the XF 400mm f/4.5 R LM OIS WR super-telephoto prime lens, with B&H promoting additional details and a “first look” video. The lens is positioned for sports and wildlife photography, building on Fujifilm’s XF telephoto lineup.
According to outlets covering the announcement, the lens uses Fujifilm’s R LM autofocus system and includes optical image stabilization (OIS). One report also highlights an “equivalent full-frame” focal length of 609mm, based on the X-mount crop factor, which shapes the lens’s reach for distant subjects.
A PetaPixel piece focused on review-style impressions, framing the lens as a high-end option for demanding uses such as wildlife and sports. That coverage emphasizes expectations about performance, while still pointing to Fujifilm’s overall glass reputation and describing the new 400mm as an addition that strengthens the company’s telephoto offerings. Other coverage centers more on the product reveal and specifications rather than independent performance testing.
