What it frames like

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

How wide 30mm sees on each sensor it covers.

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

On APS-C (Sony E, Fujifilm X, L-Mount, Nikon Z): like 45mm on full frame; f/1.4 gives about the depth of field of f/2.1 there.
On APS-C (Canon) (Canon RF): like 48mm on full frame; f/1.4 gives about the depth of field of f/2.2 there.
On Micro Four Thirds (Micro Four Thirds): like 60mm on full frame; f/1.4 gives about the depth of field of f/2.8 there.
On the larger-sensor bodies of Canon RF, L-Mount, Nikon Z, Sony E: it works with the camera in a APS-C crop mode, at fewer megapixels.
