The EF 70-200mm f/4L IS USM is a lightweight, compact L Series telephoto zoom lens with Image Stabilizer. The optical Image Stabilization in the new EF 70-200mm f/4L IS USM lens provides up to an incredible four stops of shake correction-a first for Canon IS lenses. The use of fluorite UD lens elements provides excellent optical performance in terms of resolution and contrast. These features, together with its water-and dust-proof construction, provide both the performance and portability to meet user demands.
