The NF - GFX Expander 1.26x allows Nikon F mount lenses to be mounted on Fujifilm GFX camera bodies without getting dark and / or soft corners.
The magnification factor of 1.26x perfectly matches the image circle of the full-frame Nikon lenses to the medium-format sensor of the GFX series cameras, and therefore the diagonal FOV remains exactly the same.
The optical design consists of 5 elements in 3 groups, incorporating ultra-high index Lanthanum-based optical glass as well as one element made of fused silica, resulting in extremely good performances with professional-grade f/2.8 zoom lenses. For example, a 24-70mm f/2.8 lens becomes a 30-88mm f/3.5 zoom, and a 70-200mm f/2.8 lens becomes an 88-252mm f/3.5 zoom.
Please note that because of the nature of focal extenders, the aperture values decrease by 2/3 of a stop; f/2.8 becomes f/3.5 and f/2 becomes f/2.5.
High-speed fixed focal length lenses such as the 50mm f/1.4 will be transformed into a very fast standard lens 63mm f/1.8 for the GFX system.
