The FUJINON GF45mmF2.8 R WR lens is 6th in the GF Lens Series for Fujifilm’s medium format GFX-50S. The FUJINON “GF Lenses” for the GFX-50S are known for featuring rich tone reproduction, unique colour reproduction, and high resolving power, making them popular among professional photographers and enthusiasts alike. And the GF45mmF2.8 R WR more than lives up to its predecessors, with its compact design and reliability.
Lightweight, Yet Packing a Punch
Weighing in at only 490g, the GF45mmF2.8 R WR is a highly versatile wide angle lens. It has a focal length equivalent to 36mm (on a 35mm format) and maximum F2.8 aperture, perfect for that once in a lifetime shot. With its compact and lightweight design, it’s also highly ideal for street and documentary photography.
In addition, the aperture ring has a C position on the camera body that allows the lens aperture value to be changed to suit the photographer’s preferences.
Performance Without Hassle
With its Nano GI coating, the GF45mmF2.8 R WR lens offers clear depiction performance with reduced ghosting and flare. Even those caused by incident light from diagonal angles!
The lens is also weather and dust resistant, allowing you to shoot with confidence in most environments. The lens has been sealed in ten areas, and can therefore be used in temperatures as low as -10°C, or in light rain. With its portability, stability, and compactness, it’s an optimal lens for snapshots and documentary photography.

Finally, the Tele Converter GF1.4X TC WR is a high performance teleconverter capable of multiplying focal lengths up to 1.4x. Compatible with the GF250mmF4 R LM OIS WR, its focal length will be 350mm (equivalent to 277mm on a 35mm format).
