Versatile Normal-Range Zoom. The Tamron 17-70mm f/2.8 Di III-A VC RXD’s zoom range makes it great for everyday shooting, and the fast, constant f/2.8 maximum aperture suits working in difficult lighting conditions and offers improved control over depth of field. It’s ideal for a variety of scenarios, from portraits and street snapshots, to landscapes and even close-ups.

VC Image Stabilization. Tamron’s proprietary Vibration Compensation (VC) image-stabilization system helps to offset the effects of camera shake when you’re shooting hand-held or in low light.

Fast, Accurate, and Nearly Silent Autofocus. The lens is equipped with Tamron’s Rapid eXtra-silent stepping Drive (RXD) autofocus drive system, which delivers impressively quiet, quick, and smooth focusing performance to suit both stills and video applications. There’s a 7.5-inch minimum focusing distance and a 1:4.8 maximum magnification for working with close-up subjects. Full-time manual focus override is also possible!

High-Quality Optics. The twelve-group/sixteen-element optical formula includes two low-dispersion elements and three molded-glass aspherical elements to give you high-contrast, color-accurate images across the image plane while reducing color fringing, chromatic aberrations, and distortion throughout the zoom range. Each lens element has a BBAR coating that combats ghosting, internal reflections, and flare while helping maintain sharpness and color fidelity even in strong light.

Durable, Weather-Resistant Build. A moisture-resistant construction provides greater protection when shooting outdoors, and leak-resistant seals throughout the lens barrel help protect your equipment when using in inclement conditions.
