GF lenses achieve ultra-high resolution and are capable of supporting further enhancement in future. Utilizing the knowledge cultivated through the development of the XF lenses, GF lenses are Fujifilm's finest class of lenses and were designed by amassing various technologies of Fujifilm. They are designed to fully unlock performance potential of the GFX 50S.

The FUJINON GF 23mm F4 R LM WR has a focal length equivalent to 18mm in the 35mm format and is perfectly suited for landscape and architectural applications. Despite the super-wide angle of view, distortion is kept to a minimum, and with the high-resolution performance extending all the way to the edges, sharp depiction power as if looking at an actual landscape is achieved. It features fast and quiet AF due to a linear motor, is dust and weather resistant, and is capable of operating in environments as cold as -10°C. The lens combines high performance and reliability as a professional work tool.

Low distortion with high resolving power

With a focal length equivalent to 18mm in the 35mm format, this super wide-angle lens is optimal for shooting landscapes and architectural photography. With a 12 groups and 15 elements construction using two aspherical lenses, one super ED lens, and three ED lenses, this lens suppress distortion despite being a super wide-angle lens with a 99.9° angle of view. Also, thanks to the optimal arrangement of the Super ED lens and three ED lenses, chromatic aberration of magnification is thoroughly suppressed, achieving high resolution performance all the way to the edges.

Nano GI coating

Nano GI coating has been applied to the lens that is effective on incident light entering the lens from diagonal angles due to the nature of the super wide-angle lens. Despite being a super wide-angle lens, the occurrence of ghosting and flare is effectively suppressed.

Fast and quiet AF

By adopting an inner focusing AF system to lighten the weight of the focus lens, and using a linear motor to drive the lens elements, fast and quiet AF is achieved, allowing for comfortable shooting.

Dust and weather resistant, capable of operating in environments as cold as -10°C

The lens has been sealed in nine areas, allowing you to shoot with confidence and stability, even in dusty environments and in light rain outdoors.

High operability

The aperture ring has a C position (command dial mode) to allow lens aperture value to be changed via the command dial on the camera body. A locking mechanism has been added to the A (Auto) and C positions to prevent unintended movements of the aperture dial.


Protect filter "PRF-82" and front lens cap "FLCP-82" will be released at the same timing.
