Overall, and especially for the price, I'm very pleased with the image quality of the Tamron 70-200mm f/2.8 Di Macro Lens. On the wide end (70mm), this lens is sharp wide open (f/2.8) across the entire 35mm frame. Stopping down only makes a small improvement in sharpness - reduced vignetting is the primary difference seen.

The SP AF 70-200mm F2.8 Di LD (IF) Macro is certainly a very creditable effort by Tamron to produce a high quality, yet affordable fast telephoto zoom. Indeed if we look solely at the studio optical tests, it is a resounding success, as the technical quality of the images this lens can produce is superb throughout most of the range, matching or even outperforming the much more expensive Canon 70-200mm F2.8 L IS USM.

For the price, this lens represents excellent value for money which isn't unusual for Tamron. Available in all the main mounts, it makes an ideal alternative to the OEM offerings, especially if you can live with the slightly slower focusing. The AF/MF switchover is a boon and the close focusing ability, at just under a metre, is handy too.
