Digital Camera World Verdict

Thanks to the crop factor of Fujifilm’s X-mount mirrorless cameras, this lens delivers radical reach of up to 609mm in full-frame terms. It really covers the distance in action, sports and wildlife photography, for which the super-fast autofocus system and 5-stop optical stabilizer also play into your hands. Indeed, although no lightweight at 1.4kg, it’s perfectly manageable even for prolonged periods of handheld shooting, while performance is excellent in all respects.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

For an APS-C format lens, the Fujinon XF100-400mm f/4.5-5.6 R LM OIS WR is a heavyweight in all respects. It tips the scales at almost 1.4kg and measures 95x211mm, stretching to 270mm at its longest zoom setting, somewhat dwarfing the Fujifilm X-mount camera bodies for which it’s designed. Even so, the effective zoom range of 152-609mm gives you powerful reach and, if that’s still not enough, the lens is compatible with Fujifilm’s 1.4x and 2x tele-converters.
