Fujifilm XF 500mm F5.6

4 Sept 2026 · Lens Rumour

First leaked image of the unannounced Fujinon XF400mm f/4.5 R LM OIS WR has surfaced via FujiRumors, who used it to put together a size comparison against the XF500mm f/5.6. The 400mm appears notably shorter, per the comparison, though the front section was reconstructed after the leaked shot arrived with the hood on.

Fstoppers tests the Fujifilm XF 400mm f/4.5 on the X-T50, focusing on real-world sharpness. The lens covers a 600mm full-frame equivalent on X-mount and sits about two-thirds of a stop faster than Fujifilm's 500mm f/5.6.
