Tamron's SP 24-70mm f/2.8 DI USD Lens for Sony Cameras delivers a very useful range from 24mm true wide-angle to 70mm short telephoto, useful for landscapes, interiors, portraits, street photography and much more. The continuous maximum aperture of f/2.8 makes it possible to achieve stellar results in low-light situations, while the Ultrasonic Silent Drive (USD) gives you very quiet autofocus capabilities that are ideal for shooting video.

The 24-70mm lens uses specialized high-grade glass in the three LD elements, three Glass Molded Aspherical Lenses, one Hybrid Aspherical Lens and two XR (Extra Refractive Index) glasses, for excellent image quality. Using a rounded 9-blade diaphragm, the lens delivers fine bokeh--the out-of-focus area in a photo. Moisture-resistant construction helps protect the lens from any water that comes near it. And all of this is in a compact (3.5 x 4.6"), lightweight (29.1 oz) package that won't wear you out, even carrying it all day.
