The Tamron SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) Macro is a good lens. It's well built, small, fast, light, sharp, flare resistant and affordable ($340 after rebate). It's about 1lb lighter and $800 cheaper than the Canon 24-70/2.8L.

The Tamron focuses quickly, although the focus ring turns in AF, considering the price, this doesn't bother me. The front of the lens does not rotate which is nice. It has a loud ring/click when it is stopped down, almost like there is a little bell inside, it's quite loud. The noise can be heard after each shutter release.

The Tamron 28-75mm f/2.8 XR Di Lens is a relatively small normal zoom lens that delivers good image quality and a wide fixed f/2.8 aperture for a low cost. It is a good choice for 1.6x FOVCF Digital SLR users.
