Versatile Telephoto Zoom. The Tamron 100-400mm f/4.5-6.3 Di VC USD’s versatile focal-length range makes it great for sports, wildlife, and action photographers, and for videographers who want some extra reach. The rounded nine-blade diaphragm helps create smooth bokeh when you’re using selective-focus techniques.

High-Quality Optics. The seventeen-element/eleven-group optical design features three low-dispersion elements to help minimize chromatic aberrations while producing extremely sharp, high-contrast images. An eBAND coating reduces ghosting and lens flare, and improves contrast when you’re shooting in backlit conditions.

USD Autofocus System. An Ultrasonic Silent Drive motor provides quiet, accurate autofocus performance, and enables full-time manual focus control without having to shift into a dedicated manual-focus mode. This lens gives you a 4.9-foot minimum focusing distance.

Four-Stop Vibration Compensation. The Tamron 100-400’s built-in four-stop vibration compensation minimizes the appearance of camera shake for sharper shooting in low-light conditions.

High-Quality Build. This lens’s durable, dust- and moisture-resistant aluminum alloy construction means you can use it in adverse conditions without worry. The front lens has a fluorine coating to protect it from debris and smearing.
