The lens is a Canon EF-S 18-55mm.

I recently dropped my camera from the tripod falling over while I was recording, now the camera won't AF and MF is very hard. It gets stuck easily when I try to MF it, and doesn't focus properly. I can zoom in or out, that is completely stuck. When I move the lens around I can hear a rolling noise inside it, like a marble. I had a fisheye conversion lens on it which I thought took the impact due to the paint ear on the edge it fell. I've read it costs about $200-$300 to fix this, and would prefer to fix it on my own. Does anyone know what the issue is so I can fix it?

  • "Marble rolling around"? It's toast. $200-$300 to fix a $200 lens? Buy a new one. Check to the body as well and see if that was damaged in the fall. – Gmck Sep 10 '16 at 16:32

    @Gmck that would be better as an answer. Short answers are ok. See: Short answers as comments — please resist the urge – inkista Sep 10 '16 at 17:12
  • The issue? It's broken. – Steve Ives Sep 11 '16 at 18:34

You're between a rock and a hard place: professional repairs are expensive, but a new lens is also. There are videos showing the teardown of the Canon EF-S 18-55mm, and another, and you can find more. However, this work is best done in clean-room, or at least well filtered area, and the slightest mistake can cause more damage.

As was stated, a new lens is ~US$200 or less, so professional repair does not seem cost-effective. If the lens is totally inoperative now, and you want to do this for a learning experience, it seems you have little to lose... and there is a small chance the lens can be made partially useful (e.g. but with autofocus broken), or used for parts.


Fixation, a UK authorised Canon Service Centre, don't offer a repair on the EF-S 18-55 - possibly because it's never economically viable as it's a cheap(ish) lens.
