Fujifilm G-mount lens system
The crop factor compared to the 35 mm format as a reference is 0.79. Ratio of the reference frame's diagonal (35 mm format) to the diagonal of the image sensor in question (Fujifilm GFX): $$\dfrac{\sqrt{(24 mm)^2+(36 mm)^2}}{\sqrt{(32.9 mm)^2+(43.8 mm)^2}}\approx0.790$$

As of September 2023 there are 32 lenses available for the G-mount (excluding the as yet unreleased model "Power Zoom Lens"); 19 from Fujifilm's Fujinon brand and 13 from third party companies.
