CANON - EF 70-200mm f/2.8 L IS III USMhttp://photocineshop.com/en/products/CANON-EF-70-200mm-f-2-8-L-IS-III-USM-E3PYU8
A classic revisited: this telephoto lens with large f / 2.8 aperture is one of the favorite models of amateurs, but also professionals for all types of photos.
Designed to work in the most extreme conditions, the performance of this lens has been improved for photos in bright light.
Even with large apertures, the images retain a quality worthy of the highest resolution of EOS cameras. The fast maximum aperture of f / 2.8, which remains constant over the entire focal range, allows almost twice as much light to come in as an f / 4 lens.
UD optics and fluorine-treated optics provide high contrast and excellent resolution and capture every detail, regardless of the focal length. Air Sphere Coating (ASC) and Super Spectra treatments avoid glare and ghosting problems when shooting in bright light.
Whether you're shooting action shots or twilight landscapes, the quality of Canon's legendary L-series lets you shoot with confidence in any weather. The fluorite-treated front and back elements are easy to clean and the protective seals protect the lens from dust and moisture. With its fast and almost silent autofocus, you can follow objects moving quickly in the frame. You can make manual adjustments at any time by simply turning the focus ring.
