"This is Canon’s latest incarnation of the ever popular Canon 70-200mm f/2.8. This MK III fast aperture telephoto zoom lens is an extremely versatile and popular option for professionals and amateurs in a wide variety of genres. With its fast focusing in poor lighting conditions, 3.5-stop Image Stabilisation and top-shelf weather sealing, this lens is a must-have addition to your kit." - Gunther Swart
One of the most versatile lenses available, the Canon EF 70-200mm f/2.8L IS III USM is an L-series telephoto zoom distinguished by its bright design and advanced optics. Ideal for a variety of subjects ranging from portraiture to sports, the fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects.
The optical layout makes use of one fluorite element and five UD elements to suppress chromatic aberrations and colour fringing in order to realise a high degree of clarity throughout the zoom range. An Air Sphere Coating is also featured and works to reduce flare and ghosting for greater colour fidelity and contrast in all conditions.
Complementing the speed and optics is an Optical Image Stabiliser, which compensates for 3.5 stops of camera shake to better enable working handheld and in low-light situations. 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.
