Compatible with the GFX 50S camera, the Fujifilm Fujinon GF 45mm f/2.8 R WR Camera Lens is made up of 11 lens elements in 8 groups. These includes two Extra-Low Dispersion Lens as well as an Aspherical Lens that maintains image quality by preventing chromatic aberration. It also sports a Nano GI coating to avoid ghosting and flaring. Capable of capturing wide angles through its 45mm focal length, its f/2.8 maximum aperture makes it a dependable camera lens during low-light shooting. Enhance your images by attaching accessories to the 62mm filter diameter and achieve beautiful bokeh effects with the help of the nine rounded aperture diaphragm blades. Built to repel dust and moisture, the Fujifilm Fujinon GF 45mm f/2.8 R WR Lens is also freezeproof for up to -10C. Product Features in Detail High resolving power With a construction of 8 groups and 11 elements, using one aspherical lens and two ED lenses, the Fujifilm GF 45mm f/2.8 R WR delivers high image quality and reduces aberrations. By adopting an inner focus system which moves the six lenses, the lens is able to deliver high quality images while reducing fluctuations of the aberrations caused by the change of shooting distance. 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. Dust and weather resistant The lens has been sealed in ten 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.
