Canon EF-S 18-55 mm IS ~OPERATION~

One day my Canon EF-S 18-55 mm IS autofocus(AF) was not working properly.
It can focus inward but cannot focus outwards..

I decide to open the lens to look at what was wrong with the lens.
1st look,i found out that the AF ribbon cable was ripped.Afraid of loosing my one and only 18mm wide angle lens, i close back the lens..
it took me some time before i really operate the lens..
heres some pic of whats inside of the Canon EF-S 18-55 mm IS.

~Pictures were taken by using Canon 50mm at f1.8~

After removing 4 screws, detaching 5 ribbon cable & putting away the circuit board

This is after ive remove the AF motor.

The AF motor without its cover

heres the problem.. ripped/separated/torn apart AF ribbon cable

Just for fun, ive also remove the aperture lens mechanisms and it turn out to be the hardest thing to remove at that time.. LOL

till today, my 18-55 lens is still works but with a 1 way AF..


  1. Hi Lionel, that's amazing! I just have the same problem, searching over the internet looking for solutions and just found your site. Right now I am sitting in germany on my desk - in front of me the opened EF-S and I had to laugh because it looks just identical. My ribbon cable broke at the same position! I also found a company who will sell me the cable for just 9€ (12-14$). The hard part will be to remove the lens mechanism to have free access to the ribbon cable (for later purpose to stick it to the right position. Just wanted to tell you that I was happy to see that it's not impossible to fix! Many greets from Germany, Europe. Alex

  2. Hi Alex.. wow,really? glad i could help :)
    unfortunately for me,here there are no store that sells only a part of whats inside a lens,so im still stuck with no auto focus with this lens..
    oh well.. gud luck with fixing yours, and let me know how it turns out..

  3. Hi there! I just discovered that I have the same issue. I just opened the lens and found that the ribbon cable was ripped off. Now I have to look for the new one. BTW, have you searched for the cable in online store with delivery?

    1. Hi :D well yes, ive found one.. take a look here
