Harness the incredible image quality and high-resolution capabilities of GFX system cameras with the FUJINON GF23mmF4 R LM WR and bring your photos to life in marvelous, FUJIFILM color. A super wide-angle lens that produces images with little-to-no distortion, the GF23mmF4 R LM WR is the perfect lens for framing panoramic landscapes, soaring architectural marvels, or fast-moving city streets. No matter the situation, its dependable autofocus and durable, weather-resistant design is ready to help any willing image-maker widen their creative perspective.

World-class optics, state-of-the-art engineering, and precise manufacturing combine to create the perfect wide-angle lens for any large format GFX system camera. With its 35mm equivalent focal length of 18mm, the GF23mmF4 R LM WR allows you to dynamically frame a scene and give you endless creative opportunities for architecture, landscape, or interior applications. Despite its wide angle of view, the GF23mmF4 R LM WR maintains sharpness from edge-to-edge. Also, ghosting and flare are kept to a minimum, thanks to a special Nano GI coating, applied to the lenss front element.

Producing high-resolution images from a GFX system camera requires a lens capable of resolving fine details with little-to-no distortion, from one edge of the frame to the other. This is why the GF23mmF4 R LM WR consists of 15 elements in 12 groups, including two aspherical lenses, one Super ED lens and three ED lenses. The result is a lens that creates architectural images with straight lines and crisp angles, while beautifully rendered landscapes can transport viewers to an entirely different place.

Specifically designed to react quickly and precisely, the GF23mmF4 R LM WR delivers unerring accuracy with its linear motor in a split second, with barely a sound. It is simply the perfect complement to an optical design that consistently delivers outstanding image quality. Even in the briefest of moments, the GF23mmF4 R LM WR is ready to produce the best results.

Battling the elements requires a lens that can withstand the toughest conditions and be ready to create an image at exactly the perfect moment. Thats why the GF23mmF4 R LM WR has weather-resistant seals in nine areas, protecting it against dust, moisture, and temperatures as low as -10C (14F). We may not be able to plan for the unexpected, but can certainly be ready when it happens.
