Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens - 2.8x - 70mm to 200mm - f/2.8
Incorporating Canon's second generation Image Stabilization technology, this telephoto zoom responds in as little as 0.5 seconds, while providing up to three stops of correction for camera shake. Its AF system has been refined for better response time and tracking speed. And even the new 8-blade circular aperture offers a more pleasing out-of-focus image. Constructed to pro standards, this fast zoom is also highly resistant to dust and moisture, too.
