Canon
EF 300mm f/2.8L IS MkII USM
Professional telephoto lens
An excellent super-fast telephoto lens in the Canon L-series range. It is extremely light for its class and a third IS mode offers up to four extra stops of performance. Fast and quiet auto-focusing provided by the ring-type Ultra-Sonic Motor (USM). Fluorite optics mean shraper images with less chromatic aberration, and fluorine coating keeps smears and fingerprints to a minimum. It also comes with a security feature - a slot for wire-type locks to prevent theft.
