Tamron's SP AF17-50mm f/2.8 XR Di II VC lens is designed exclusively for cameras with APS-C sized sensors and covers the popular standard zoom range of focal lengths. On Nikon cameras it is equivalent to 26-78mm in 35mm format, while on the Canon EOS 40D body we used for our tests, the equivalent range is 27-80mm. The fast f/2.8 maximum aperture applies across the focal length range.
