I'm having problems with the lens. I've tried auto-focusing with my other lenses, and it works fine. It can only auto-focus one way, i.e. the focusing ring is still able to move, but only able to turn clockwise (i'm looking at the camera from the front).

Anyone with a similar problem or solution? Help! :(

  • Are you trying to autofocus or manually focus? If autofocus, the focusing ring would be engaged by the motor and I don't think it would turn. I supose you've checked the MF/AF switch?

  • So you can switch to MF and reset it, but in AF mode it will only go the one direction? If so certainly sounds like a fault with the lens, not something you could fix by changing settings.

    Just be careful about how much you pay to have it fixed, you can pick up a used EFS 18-55 for next to nothing (more than 10 sold for less than $60 on eBay this month alone, most of those for around $40) there are so many people trying to sell their kit lens after getting a better lens the market is saturated

Its not clear that sending that lens in for service is worthwhile. If its new, warrantee service is fine, but the lens sells new for about $100, and the minimum service charge is likely to be $100.

Save up for a better lens, or if you have to, pick up a replacement. The 50mm F1.8 is nearly as cheap and a much better lens (but its not a zoom).

I have the EFS 17-55 F2.8 and I love it.

  1. Maybe your reverse motor is stuck in the helix / bent plastic path. You need to push it to adjust. http://www.fotomozaic.ro/artikel.php?idstory=225&s=1

  2. The motor has weak, broken gears.
