The 100-400mm f4.5-5.6 R LM OIS weather-resistant super-telephoto lens adds to Fuji’s already impressive X-Series of mirrorless lenses with a 35mm focal length equivalent of 152-609mm. The lens uses an optical construction of 21 elements in 14 groups to help reduce chromatic aberration and deliver ultra-sharp images across its focal range. The 5.0-stop image stabilisation system and linear motor work in synergy to achieve quiet, accurate and fast auto focusing.
