The EF 70-200mm F2.8 L IS USM was introduced way back in August 2001, supplementing (but not replacing) the non-stabilized 70-200mm F2.8 L USM in Canon’s highly regarded telephoto lineup. This is a lens which can truly be described as a professional workhorse, with robust build (including dust and moisture resistance), wide F2.8 maximum aperture, fast and silent ultrasonic autofocus motor, and optical image stabilization for hand-holding at slow shutter speeds. The optical design is somewhere on the far side of complex; it features 23 elements in 18 groups, with 4 UD elements to provide compensation for chromatic aberration. According to Canon, this gives a ‘high-resolution, high-contrast optical capability’, as demanded from a lens which needs to perform all day, every day in the hands of professional photographers across a wide range of subjects and conditions.

Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens for Canon SLR Cameras- Review:
FAST! SHARP AND SOLID WITH IS TO BOOT!
This is the best lens you can get in this zoom range for the Canon EOS. It’s not the cheapest and it’s not the lightest, but it’s the best. This lens is fast, it has excellent optics, the build quality is very solid and the image stabilization (IS) feature works wonders for hand held shooting. If you shoot hand held in marginal light, this is the lens for you. If you always use a tripod, you don’t really need IS — take a look at the less expensive non-IS version of this lens. If you always shoot in good light, the lighter and even less expensive 70-200mm f4.0 may do the job for you. But for me, the extra stop of light and the IS make the difference between unusable images and great images. This is an awesome lens.
