Canon EF 70-200mm f/4L IS II USM Lens

The Canon EF 70-200mm f/4L IS II USM is a light constant-f/4 telephoto zoom for full-frame EF-mount cameras, well suited to portraits, events, and outdoor sport where a fast f/2.8 lens would be heavier than the job needs. The optical image stabilizer corrects up to five stops of shake across three modes for handheld shooting and panning.

The design packs 20 elements in 15 groups, with one fluorite and two UD elements to hold contrast and suppress color fringing, and focuses down to 3.3 feet through ring-type USM. The weather-sealed L-series barrel takes 72mm filters. It ships with the ET-78B hood, caps, and LP1224 case. Canon part number 2309C002.
