What it frames like

Its full-frame-equivalent focal length on the sensor it was made for.

How wide 10mm sees at its wide end on each sensor it covers.

f/2.8 wide open, to scale against f/1.4.

On APS-C (Sony E, Fujifilm X, L-Mount): like 15-27mm on full frame; f/2.8 gives about the depth of field of f/4.2 there.
On APS-C (Canon) (Canon RF): like 16-29mm on full frame; f/2.8 gives about the depth of field of f/4.5 there.
On the larger-sensor bodies of Canon RF, L-Mount, Sony E: it works with the camera in a APS-C crop mode, at fewer megapixels.
