Fujifilm XF400mm F4.5 R LM OIS WR: A Compact Super-Telephoto That Finally Completes the X-Mount Lineup
Fujifilm officially announced the FUJINON XF400mmF4.5 R LM OIS WR on 4 September 2026, a super-telephoto prime designed for APS-C X Series cameras. With a full-frame equivalent focal length of 609 mm and a maximum aperture of F4.5, the lens fills the gap between the XF200mm F2 and the XF500mm F5.6. It is aimed primarily at wildlife, sports, and aviation photographers who need substantial reach without the usual bulk of optics in this class.
