Metabones has released the Canon-EF version of the 1.26x Format Expander for the Fujifilm GFX.

Press Release

Vancouver, Canada, November 16, 2020 – Will this full-frame EF mount lens sufficiently cover the medium format sensor of Fujifilm GFX cameras? With Metabones® EF-GFX Smart Expander™, the answer is always “yes”.

Multiplying the focal length by 1.26x and the F-number by the same amount, Metabones EF-GFX Smart Expander perfectly matches the image circle of full-frame EF mount lenses to the medium-format sensor of the GFX series cameras, with the diagonal field-of-view (FoV) remaining 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 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.  And perhaps most exciting of all, the 11-24mm f/4 Canon becomes an extremely sharp 13.8-30.2mm f/5 without any disturbing vignetting or corner aberrations. Due to 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 63mm f/1.8 standard lens for the GFX system.
