Customer Reviews

Entirely satisfied
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 buy (but be careful!)
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.

Great value
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.
