The lens employs four UD-glass elements to minimize chromatic aberrations, creating sharp, high-quality images regardless of the application. The constant f/2.8 maximum aperture, meanwhile, makes the lens extremely popular among professionals.

This is probably Canon's best value in a mid/long zoom.

I got this the same day I purchased my 30D...along with the EF-S 10-22 and the EF 24-70 2.8L. Talk about pleased! No regrets whatsoever.

This lens just screams quality. Images just pop out at you. If you're considering the f/4 model...take a hard look at this one. Add a hood (cha-ching) and (yikes) the $100+ tripod ring and the value of this lens really shows. It's a bit larger & heavier but look what you gain! If you're one of those that considers the sweet spot of a lens to be stopped down a step or two just look at where that puts you on the f/4 compared to this one. And the focus speed is nothing short of "holy mackerel that's fast!"

Sure, you could spend a few more bucks and get the IS version...but frankly, to me at least, if it's that important I'll be using a tripod anyway. Hmmm, just took the shakes out of the equation.

All in all, a great lens at a decent price.
