The Tamron 70-210mm f/4 Di VC USD for Canon is a relatively compact telephoto zoom that’s compatible with both full-frame and crop-frame EF-mount cameras. Key features include:

Versatile Telephoto Zoom. When used on a full-frame camera, the Tamron 70-210mm f/4 Di VC USD is an exceptional choice for sports photography, action photography, and portraiture. Its constant f/4.0 aperture is consistently bright throughout the zoom range and gives you great depth-of-field control for selective focusing, but is probably a bit too slow for low-light shooting.

High-Quality Optics. The twenty-element/fourteen-group optical design features three low-dispersion elements to help minimize chromatic aberrations while maximizing clarity and sharpness. The rounded, nine-blade diaphragm provides smooth background blurring with circular out-of-focus highlights.

Built-In VC Image Stabilization. The built-in vibration compensation minimizes the appearance of camera shake by up to four stops for sharper handheld shooting in less-than-stellar lighting.

Ultrasonic Silent Drive Autofocus. The USD focus motor provides fast, nearly silent autofocus performance that’s great for capturing moving subjects. The motor also gives you full-time manual control for precision adjustments. Its best-in-class 1:3.1 maximum magnification ratio and 3.1-foot minimum focusing distance make it great for working with close-up subjects.

Durable Build. The 70-210’s moisture-resistant construction means it’s able to hold up in less-than-ideal shooting conditions, while the front element has a fluorine coating to protect it from smudges and debris. It’s 6.8 inches long and slightly under 2.0 lbs., making it relatively compact and light for a lens with its range. On top of that, its internal zooming mechanism means that its overall length doesn’t change during use.

TAP-in Compatible. This lens is compatible with Tamron’s TAP-in Console for Canon, enabling fine-tuning select focusing adjustments and for updating lens firmware.
