Fujifilm GF 23mm f/4 R LM WR Lens

An Ultra-Wide Prime for Medium Format Landscapes

The Fujifilm GF 23mm F4 R LM WR Lens is an ultra-wide-angle prime designed for Fujifilm's GFX medium format camera system, built for photographers who want a dramatic, expansive field of view without sacrificing image quality. With a viewing angle of about 100 degrees, equivalent to an 18mm lens on a full-frame camera, it delivers a genuinely wide perspective well suited to landscape, architecture, and interior photography.

Designed for Expansive, Detailed Scenes

This lens is made for shooters who need to capture grand, sweeping views with precision. Its 35mm-equivalent focal length of 18mm allows for dynamic framing of a scene, opening up creative opportunities for architecture, landscape, and interior applications, making it a natural fit for photographers working in expansive or tightly confined spaces alike.

Optical Performance and Build

The lens features a weather-resistant body housing an optical design comprised of 15 elements in 12 groups, with two aspherical lenses, one super ED lens, and three ED lenses, along with Nano GI coating to suppress ghosting and flare. Despite its wide angle of view, it maintains sharpness from edge to edge, and weather-resistant seals in nine areas protect it against dust, moisture, and temperatures as low as -10°C (14°F).

Fast, Quiet Autofocus

A high-speed linear AF motor delivers quiet, internal focusing, typically locking onto a subject in about 0.25 seconds in good light with minimal hunting. A traditional aperture ring on the lens barrel allows aperture adjustments in 1/3-stop increments.
