FUJIFILM GF 45-100mm f/4 R LM OIS WR Lens

Overview

The FUJIFILM GF 45-100mm f/4 R LM OIS WR is a standard zoom lens built for FUJIFILM's G-mount camera system, covering a versatile 45 to 100mm range (36 to 79mm Full-Frame Equivalent) that spans wide-angle to portrait-length framing. A constant f/4 maximum aperture holds exposure steady throughout the zoom range, while an optical design built around a Super ED element, an ED element, and three aspherical elements works to control chromatic aberration, field curvature, and distortion for sharp, accurate imagery. The lens suits photographers who want one flexible zoom to cover everyday shooting situations without swapping glass.

Balancing the optics is a five-stop optical image stabilization system that reduces camera shake for sharper handheld results, paired with a linear autofocus motor that delivers fast, near-silent focusing for stills and video alike. Internal focusing keeps the barrel length constant while focusing, and a rounded nine-blade diaphragm helps produce smooth, pleasing background blur. Dust, freeze, and weather-resistant construction extends the lens's usefulness into demanding outdoor conditions, and a physical aperture ring with a dedicated C (Command) position gives direct, tactile control over exposure.

Aspherical and ED Glass Elements

A Super ED element and an ED element greatly reduce chromatic aberrations and color fringing throughout the zoom range, while three aspherical elements control field curvature, distortion, and spherical aberrations to maintain a high degree of sharpness and accurate rendering.

Five-Stop Optical Image Stabilization

The built-in stabilization system compensates for up to five stops of camera shake, helping to realize sharper imagery when shooting handheld across the lens's zoom range.

Weather-Sealed Magnesium Alloy Build

A dust- and weather-sealed magnesium alloy construction holds up in freezing conditions down to -10°C, making the lens a reliable choice for shooting outdoors in demanding weather.

Physical Aperture Ring with C Position

A physical aperture ring allows intuitive, tactile adjustment over exposure settings and incorporates a C (Command) position to permit camera-based aperture control when preferred.
