Features to focus on: low-light performance and optimum image control.
With their wide f/2.8 apertures, these superb high-speed zooms let you take natural-looking pictures handheld even in low light without using flash. And when you shoot them at their widest apertures, the resulting shallow depth of field lets you create dramatic effects by softening surrounding details so the subject seems to "pop" off the background—a technique used by many top pros. Crisp performance is maintained at all aperture and focal-lengths. Tamron's fast zoom lenses offer photographers of all levels the ability to shoot with fast glass at an affordable price.
