Hello,

I have a Canon EOS 350D camera. I have two zoom lenses, an EF 75-300 and the one sold with the camera, the EFS 18-55. Everything works well with the 75-300, however, for some time now I can't take more than one picture with the 18-55 without the message ERROR 99 appearing, preventing me from taking photos.

Do you have a quick solution because I am currently on vacation and would like to take pictures.

Thank you for your valuable help and happy holidays.

    Hello,
    I also had the issue of error 99 on a 300D with the EFS 18-55mm lens (2004 model, without stabilizer).
    The error occurred when the lens was between 18 and 24 zoom. Beyond that, it worked fine.
    In case of error 99, the camera needed to be turned off and back on.

    Here’s how I resolved the issue. On the lens, next to the camera, using a small Phillips screwdriver:
    - Unscrew the 4 front screws
    - Unscrew the 2 smaller screws on the side of the connector
    - Remove the cover
    - Remove the 2 discs acting as seals. Be careful with their position, otherwise it will take some trial and error to find the right position to screw the 4 screws back in.
    - With tweezers, disconnect the 2 orange ribbons. I didn’t try too hard to disconnect the gray one, as the connector is different and it’s not necessary.
    - Unscrew the 2 screws holding the small board.
    - There’s a “comb” behind that slides on tracks.
    - Soak a piece of paper like “Sopalin” with burning alcohol (or 90° alcohol)
    - Wipe the paper on the tracks. They were dirty. It got black. I also gently wiped the paper on the “comb”
    - Reassemble.

    I did a few tests, and now my lens is working well again!
    I got started after watching the following video:

    The lens shown is not exactly the same, but the principle is the same.

      Thank you for the tutorial. I have the same issue between 18 and 24 mm on an EFS 18-55mm, but the error code is err01 with an American Canon body, the EOS Rebel T3i. The problem is much more pronounced in bright light than in low light.

      I just solved the issue with a 200 Canon telephoto lens. A small screw (loose) on the ring was preventing perfect contact. The screw being stubborn to screw in and unscrew, I took the radical solution of removing it. The lens works wonderfully now.

      @ Fred
      Thanks for the tip, but apparently it's a problem with a 18-55 mm and not a 200 mm. And on the 18-55, I don't see any screws sticking out?
      My error 99 problem is still present again after a very short interlude following the careful cleaning of the contacts (my message from 11/3/2011).

    Pfff I have a CANON 450D and I have the same problem!!!
    Error 99!!! It tells me to switch to OFF and then to ON...
    But when I switch back to ON, nothing happens, the camera is stuck!
    I haven't found any explanations... Suddenly the camera starts working again after several days... then it goes back to Error 99!
    I'm really disappointed with CANON! And disgusted!
    If anyone has an explanation...
    I've heard it might be a series problem?
    These occasional breakdowns are difficult to solve...
    It's like a car that breaks down that works when it's in the garage!!!
    You can only find the fault when it's broken!

    I did it but still nothing... it always shows error 99.

    Is the zoom broken???

    Thank you for everything.

    I had (I have!) the same issue with the Canon 18-55 lens mounted on the EOS 450D. So I tried it on an EOS 20D: same result.
    I applied the method recommended by ac3. That's what I was thinking of doing, and it reassured me in my idea. I used a jeweler's loupe as a precaution to check that there were no fibers left from the cotton swab used. And it works!!! Thank you for your help.

    Hello,

    After many attempts, I couldn't repair my lens.

    So, I bought a new one.

    Thank you for your replies.

    You’ll tell me it’s a bit late since you’ve replaced it, but have you tried this (seemingly defective) lens on another Canon device?

    I'm replying a bit late... it's not a problem with the series or anything, it's just that you must have changed or removed the lens in a place where there was dust in the air... this confuses the device and it can no longer focus because it directly sees the marks left by the dust. Remove the lens and then clean it gently and you'll see it will work again right away!
