Super Telephoto Zoom. With its 152-609mm equivalent focal length after sensor crop, the Fuji XF 100-400mm f/4.5-5.6 R LM OIS WR is your go-to zoom lens for long-distance sports and wildlife photography. While not the brightest, the f/4.5-5.6 aperture is plenty fast for shooting fast-moving subjects in daylight to moderately low-light conditions.

Twin Linear Autofocus Motor. Provides smooth yet quick performance for fast-moving subjects. Built-in focus limiting switch allows you to constrain focus when shooting distant subjects, or disengage to enable the full range.

Optical Image Stabilization. Provides five stops of stabilization, according to Fuji.

Optics. The 14-group/21-element optical formula offers a combination of five ED elements and one Super ED element to minimize chromatic aberrations and fringing throughout the zoom range.

Professional Build. Thirteen distinct weather seals across the barrel make this lens a strong workhorse in even the poorest of conditions. The included tripod ring enables tripod/monopod use (recommended for extended shooting periods), and the included lens hood features a sliding window for better CP and variable ND filter use.
