All info about Canon 70-200mm f2.8 L III

One of the most versatile lenses available, Canon 's EF 70-200mm f/2.8L IS III USM is an L-series telephoto lens 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 aperture excels in challenging lighting conditions and also offers greater control over depth of field to isolate subjects. The optical design uses one fluorite element and five UD elements to suppress chromatic aberrations and color stripes for a high degree of clarity throughout the zoom range. An Air Sphere coating is also featured, reducing glare and ghosting for greater color fidelity and contrast in all conditions.

Complementing speed and optics is an Optical Image Stabilizer, which compensates for 3.5 stops of camera shake to better enable handheld operation and low-light situations. A ring-type USM and internal focusing mechanism also offer quiet, accurate autofocus, as well as full-time manual focus override. In addition, this lens is weather-sealed for use in harsh environmental conditions.

• The versatile telephoto zoom is designed for full-frame EF mount DSLRs Canon , however it can also be used with APS-C models where it provides an equivalent focal length range of 112-320mm.
• The constant constant f/2.8 maximum aperture delivers consistent performance throughout the zoom range and offers remarkable control over depth of field for working with selective focusing techniques.
• One fluorite element and five ultra-low dispersion glass elements significantly reduce color stripes and chromatic aberrations for greater clarity and color fidelity.
• An air sphere coating (ASC) has been applied to the lens elements to reduce backlit ignition and ghosting for sustained light transmission and high contrast in bright lighting conditions.
• An optical image stabilizer helps minimize the appearance of camera shake by up to 3.5 stops of shutter speed to enable better operation in low-light conditions and with slower shutter speeds. In addition to the standard single-shot IS mode, a second mode optimized for panning is also available.
• A ring-type ultrasonic motor (USM), along with an internal focusing system, is employed to deliver fast, accurate and quiet autofocus performance, as well as full-time manual focus override.
• The focus limiter switch allows you to restrict focus to two different ranges to suit different applications: 3.9'-infinity or 8.2'-infinity.
• The rounded nine-blade diaphragm contributes to a pleasant out-of-focus quality that benefits the use of shallow depth of field and selective focusing techniques.
• A weatherproof design protects the lens from dust and moisture to allow use in inclement conditions. In addition, fluorine coatings have also been applied to the front and rear lens elements for greater protection against fingerprints and smudges.
• A removable rotating tripod collar is included that benefits working with the lens on top of a tripod or monopod.
• Compatible with optional EF 1.4X and EF 2X teleconverter
