@Vadez, @Mahoney: When the autofocus isn’t working, the camera won’t be able to take a picture. This is why manual mode works. A lot of these suffer from a broken ribbon where it has to bend when the lens is going in and out. If it is one of the kit lenses, it isn’t likely worth having fixed, but the DIY solution doesn’t look too bad. You can find Youtube videos, some better than others.
