(Refurbished Excellent) Fujifilm GF 23mm f/4 R LM WR - G-mount Camera Lens

The Fujifilm GF 23mm f/4 R LM WR Lens is an elite, ultra-wide-angle prime lens custom-engineered for Fujifilm’s G-mount GFX medium format mirrorless systems. Providing an expansive field of view equivalent to an 18mm lens in the 35mm full-frame format, it is the quintessential tool for landscape, architectural, interior, and travel photographers who demand an uncompromisingly wide perspective paired with the extreme resolving power of a large-format sensor.

The optical design of this lens is a masterclass in distortion control. It features a complex layout of 15 elements in 12 groups, incorporating two aspherical elements, one Super ED element, and three standard ED (Extra-low Dispersion) elements. This meticulous configuration effectively suppresses spherical and chromatic aberrations, resulting in pristine, high-contrast imagery that retains tack-sharp detail all the way to the extreme corners of the frame—even when shot wide open at f/4. Furthermore, Fujifilm's proprietary Nano GI coating has been applied to individual elements to combat surface reflections, ghosting, and flare under harsh diagonal lighting.

Built to withstand the rigors of professional field production, the GF 23mm f/4 features a robust Weather-Resistant (WR) construction. It is sealed at nine strategic points across the lens barrel, making it completely dust-proof, moisture-resistant, and fully operational in freezing temperatures as low as -10°C. Autofocus performance is driven by a high-torque Linear Motor (LM), delivering near-instantaneous, whisper-quiet focus adjustments that keep pace with live view tracking and fast shooting workflows.

Key Features:

Ultra-Wide Medium Format View: 18mm full-frame equivalency offers a dramatic perspective with virtually zero optical distortion.

Extreme Resolution Control: Sophisticated ED and Aspherical glass layout optimized to easily feed 50MP and 100MP+ GFX sensors.

Quiet Linear Motor (LM): An internal focusing system provides smooth, ultra-fast, and silent AF tracking suitable for both stills and video.

Physical Aperture Ring: Includes a tactile manual aperture ring with an integrated "Command" position lock, allowing users to adjust exposure settings directly from the camera body dial.

Fluorine Protective Coating: The front lens element is treated with a water- and oil-repellent fluorine coating, making it easy to wipe away fingerprints and outdoor debris.
