What it frames like

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

How wide 18mm sees at its wide end on each sensor it covers.

f/3.5 wide open, to scale against f/1.4.

On APS-C (Nikon F): like 27-600mm on full frame; f/3.5-6.3 gives about the depth of field of f/5.2-9.4 there.
On APS-C (Canon) (Canon EF): like 29-640mm on full frame; f/3.5-6.3 gives about the depth of field of f/5.6-10.1 there.
On the larger-sensor bodies of Canon EF, Nikon F: it works with the camera in a APS-C crop mode, at fewer megapixels.
