Tamron's SP 24-70mm f/2.8 DI VC USD Lens for Nikon 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 combined with built-in
Vibration Compensation image stabilization make 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.
