Tamron
SP AF 70-200mm f/2.8 Di VC USD for Canon
Professional telephoto zoom lens
With a range from short to medium telephoto and a constant f/2.8 aperture, this lens is an excellent choice for sports, nature, and wedding photography. The fast f/2.8 aperture lets in plenty of light for low-light photography, and its diaphragm has nine rounded blades for rendering pleasing bokeh. Further improving its low-light performance is the inclusion of Vibration Compensation, which lets you use a shutter speed several stops slower than would otherwise be possible when shooting without a tripod. The Ultrasonic Silent Drive makes for quick and quiet focusing.
