Inexpensive entry-level short zoom. Good value for the money, especially if you don't have anything to cover this focal range. Build quality seems a half-notch above the standard Rebel XT kit lens.

Great little short lens for any use, but you can wreck the autofocus mechanism when installing the lens shade. This may also happen when removing it but seems more likely when putting it on. The problem is the force required to lock it in place or remove it exceeds what the engaged autofocus gear can handle (probably a plastic gear in there somewhere?). I almost ruined mine. In my case it seems somehow the gear(s?) was/were disengaged from one another when I first installed the shade. The camera no longer autofocused! I gently rotated the lens barrel back in the other direction and a slight click re-engaged the focusing gears. Mine is fine now, smooth, fast and quiet. So do your self a favor, the SOLUTION is to always switch to "M" = manual focus when installing, removing AND storing the shade back onto the lens front. All in all a great lil lens for a pretty niffty price.

It's built tougher than the 18-55 Canon kit lens and is just as sharp or sharper. I'd say it's a very good value for the money.

I have used a number of Sigma lenses throughout the years and I have been quite satisfied. I have a 28 - 300mm lens that I used with my 35mm Canon A2e. A few years ago when I made the switch to digital, I called Sigma and for around $75, they converted the lens to work with my new digital equipment. I have 3 Sigma lenses that I use now. I have had the 18-50mm less than a year and it takes great photos, HOWEVER, when you twist the lens hood off and on the lens, it turns the focusing gear. Mine has stripped out and you can hear gears grinding as the camera tries to focus. Somehow it does still manage to focus but it is slower and quite noisy. I know it is only a matter of time before it stops working altogether. I have replaced this lens with another Sigma, but I chose a higher end model with internal focusing. The 18-50mm would be a great lens at a great price for the occasional user if much care is taken with the hood.

Ok lense while it lasted but AF was sketchy for a few weeks before it wouldn't work at all.
