Lens Error and Dim


Newbee here.

I got a stock 18-55 mm Canon Lens that stopped working few months ago.
It just started to give error messages and i noticed that the image is dim when you look into it.

Is there a DIY fix for this?

Thank you very much

    When you look through the lens when its off the camera, is the aperture stopped down or do you only see glass?

    I think I got the same problem. I can see that the lens blades are partially shut. Very small hole.

    Please help!

    I'm willing to dissect it if necessary!

Thats usually a sign of aperture failure. The lens will likely need parts. Check for someone local to make the repairs, always cheaper than factory service. You can search from this site.

Last i heard of the same occurance on a 24-105, it turned out to be a problem with the main board on the lens. Sounds like it needs CSC. Better send it in. Is the lens still under warranty?

Lens stopped working after holding lens when on auto focus

error 99 may be the only error that the camera can identify with the problem. Generally this is dirty contacts in the camera and on the lens. The fix is to rub them with a pencil eraser and ensure no rubber swarf gets inside the camera. ( Hold upside down and use a blower and brush for cameras after doing it. Do the same to the lens contacts and re position turn on camera and see if it works ok now.

Hello, I bought a printer a few months ago but it doesn't seem to work. I've installed the proper drivers but every time I try printing sth a got a message ''Service error 5100, cancel printing and then...


I could make several suggestion to "fix" the problem, such as clean the timing strip, etc., but since your printer is still under warranty, I'd suggest contacting Canon for a repair / replacement due to a potential hardware problem. You shouldn't be getting a "Service error 5100" after a few months.

Hope this helps.

Canon power shot sx100is LENS ERROR

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...

Don't want to get your hopes up too high, but here are some things that you can do to try to correct it. They only seem to work for about 40% of the lens errors, but if the camera is out of warranty, they're worth a try.

The lens on my canon won't close shut and now it won't work.

If it's still under warranty, go to Canon's website and arrange for a repair.

AF 70-300 causes error 99 in my Canon 300D

This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.
