Both freshly-announced Metabones EF-GFX Smart Adapter and 1.26x Smart Expander allow mounting full-frame Canon EF lenses on FUJIFILM GFX medium format cameras while providing electronic lens communication for AF, IBIS, smooth iris, and EXIF data. The Expander multiplies focal length and f-stop of the lens by 1.26x and covers the entire GFX sensor. The idea of adapting full-frame lenses on medium format cameras is not entirely new. In the case of FUJIFILM GFX medium format cameras, the selection of native G-Mount lenses is not very large and lenses with Canon EF mount happen to be in the kit of most filmmakers already, so why not make use of them? In the past we have seen such adapters already – there is, for example, the Laowa Magic Format Converter with an optical element or FotodioX Vizelex Cine ND without optical expander (but with a built-in V-ND filter). Kipon also makes such an adapter. When it comes to lens mount adapters with optical elements, I think Metabones usually produces a good image quality.

This expander multiplies both focal length and F-stop of the lens by 1.26x, enlarging the image circle to cover the entire sensor of FUJIFILM GFX medium format cameras. The diagonal FOV (field-of-view)...
