Canon EF 70-200mm f/4L IS USM review
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.
