Description — Fujifilm 100-400mm f/4.5-5.6 R LM OIS WR
The Fujifilm XF 100-400mm f/4.5-5.6 is a telephoto zoom lens built specifically for the Fujifilm X mount mirrorless system. Designed around the APS-C format, it delivers a focal length range of 100mm to 400mm, giving photographers considerable reach for distant subjects. The maximum aperture starts at f/4.5, providing reasonable light capture at the wide end of the zoom range. Optical image stabilization is integrated into the lens design, helping to minimize the impact of camera shake that becomes more pronounced at longer focal lengths.
The lens accommodates autofocus and manual focus modes, offering flexibility across different shooting styles and subject types. A 77mm filter thread at the front makes it straightforward to attach standard photographic filters. Weighing 1,375g, this is a sizeable and substantial lens, so photographers should plan accordingly when considering hand-held use over long periods.
As a zoom type lens, it provides versatility within a single barrel, avoiding the need to swap between multiple primes when working at varying distances.
