Fujifilm G mount is a lens mount designed by (quite obviously) Fujifilm in 2016 for digital mirrorless cameras with medium-format sensors. It is a bayonet mount with three tabs, a focal flange distance of 26.7mm and a throat diameter of 65mm, designed exclusively for a 44×33mm medium-format sensor with an aspect ratio of 4:3. There are no mechanical linkages between the camera and lens, it is a fully electronic mount.

Compared to the usual 35mm format, the crop factor of G mount lenses is 0.79×.

Note: this reference currently counts only official 1^st party, FujiFilm lenses.
