Zoom lens

A zoom lens by Canon for APS-C cameras, 18-135mm f/3.5-5.6.

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 (Canon) (Canon EF): like 29-216mm on full frame; f/3.5-5.6 gives about the depth of field of f/5.6-9 there.
On the larger-sensor bodies of Canon EF: it works with the camera in a APS-C crop mode, at fewer megapixels.
