I've been having troubles with the zoom of the camera. I can only set the level from 18 to 24 when I used to be able to choose what ever value I wanted (between 18 and 55mm of course!!). The 'zoom wheel' just stops when it reaches 24mm. I don't know if I unintentionally set the camera for this strange function or the zoom is broken. Thank you all!!!
The zoom on this lens (as with most DSLR lenses) is manual, so there's no settings to control. Sounds like it's broken -- possibly a small bit of grit in the mechanism.
You could probably get it repaired cheaply (and it'd probably be done under warranty for free, as long as you haven't been rolling around in the sand dunes with it, and of course if your warranty still applies), but you might want to take it as an excuse to upgrade beyond the kit lens.
