Z is for... Zoom lenses

Canon's lineup of zoom lenses ranges from the EF 8-15mm up to the EF 200-400mm f/4L IS USM Extender 1.4x which, with its built-in teleconverter, goes up to a focal length of 560mm. Regardless of focal length, all Canon zooms offer an AF/MF switch on the lens barrel, so you can choose to rely on the autofocus, or fine-tune the focus manually (using Live View) when the switch is set to the MF position.

ZONE AF


Zone AF enables you to manually select a zone, or cluster, of AF, points out of all the AF points on your camera. For example, the EOS 5D Mk Ill lets you choose from nine zones spread across its 61 AF points. You can navigate through the zones via the AF point selection button and the M-Fn button.
