Canon EF 200mm f2L IS USM
Canon has pulled out all the stops for the newest telephoto addition to their lens family. The f2 maximum aperture is ultra-fast for the telephoto category. Canon has used a completely new optic system with fluorite and ultra-low dispersion elements. The optical image stabilization system allows for shooting up to four stops slower without blur. This lens also lives up to Canon's reputation for fast yet quiet autofocus motors. The construction has also been improved, with added moisture-resistance, though the lens is heavy at 5.6 pounds. Designed for full frame cameras, this lens' price puts it out of reach for many enthusiasts.
