The EF 70-200mm f/4L IS II USM from Canon is an impressively versatile telephoto zoom. Well-suited for a range of subjects, from events to portraiture to sports, this zoom is characterised by its constant f/4 maximum aperture to strike a balance between consistent performance and portability. Its optical design includes a pair of UD elements and one fluorite element to greatly reduce chromatic aberrations and colour fringing.

This optimised design, along with a Super Spectra coating, also helps to control flare and ghosting for greater contrast and colour accuracy when working in harsh lighting and backlit conditions. Version II of this popular lens also sees the inclusion of a revised Optical Image Stabiliser, which now compensates for five stops of camera shake and offers three distinct stabilisation modes to suit different shooting applications. A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions.
