Tischer's Review of the
"SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) Macro"

(about the same size and weight as a can of beer, but that's where the similarities end)
Drink that beer and let "SP AF XR DI LD ASP IF" just roll off your tounge!

Before I get too far into this review, let me make a point that this lens only costs about $330 brand new.

I like the size and the range of this lens, my 70-200 rarely gets used, and is basically wasted space in my camera bag. So the 28-75 (with petal hood) and a prime will fill the space it took nicely. From B&H: "This Di lens is currently the most compact and lightest in the history of fast zoom lenses"

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.
I love the Tamron lens cap. It has pinch points at the center of the cap, as well as on the rim. This allows you to take the cap off when the hood is installed. The filter threads are the same as the Canon 70-200 f/4L, 67mm. Tamron includes a free hood with this lens (doesn't fit Canon 70-200). The rear lens cap will only screw on if you line up the dots which is really annoying. The rear cap for some reason does not fit efs lenses.

f/2.8 can leave your dof a bit too shallow for doing candid portraits, sometimes its hard to get the entire group of people in focus, I often stop down to f/4.

Sharpeness tests @28mm were repeated with my 1dmk2
