'Error 99' indicates some problem with the AF contacts. This is a common error in Canon lenses. It could indicate a very simple problem like dirty contacts or a much serious one like the breakage of USM cable.
As a first step, you can try cleaning the lens and body contacts (the metal contacts between the lens and body) using a pencil eraser. Be careful to hold the body facing down so that no dust falls inside. After cleaning both the lens and the body contacts, re-attach the lens and try shooting. If the AF does not work still, you need to take the lens to an authorized service center.

Error 69


Do you mean error 99? An error 69 is not listed in the manual. Error 99 mainly occurs with non-canon lenses, and indicates a communication problem between body and lens. Which still does mean nothing more than: it could be anything... Try cleaning the contacts. Or mounting another lens.

My canon ds6041 displays err 99 when i try to capture light aur object in sun light.What should i do i'm using 70-21-mm lense


Usually this is cased by shutter failure or failure of the aperture unit in the lens. Try another lens and see if you get the same error message - that will tell you if the problem is in the camera body or lens

What is error 99 in canon eos 20d


It's a frustrating catch all error and needs service.The camera may have any one of numerous issues or lens issues. If you have more than one lens, see if the error occurs with both lenses on. If not then it's a lens error. A camera repair facility can plug unit the camera and download a more accurate troubleshooting code. Royal Camera Service in Hanover Park, IL is good source for this problem. The replaced the shutter on my 20D when I got the error 99 code.

I dropped my canon rebel xsi from about 7feet, but it still took pictures after i checked it. nothing cracked, not the lense, or the screen. but than about an hour later, when i tried taking pictures it...


It could be several problems. One is a bad contact between lens and camera body, clean the contacts , check for damage and try another lens if you have one. Try another memory card. Another problem could be with the shutter which would need the camera to be repaired by canon.

Error 99 on EOS Canon 450D


This is what the people at the canon tech support say to do for error 99



read this!! :)

The guy at tech support listened and then told me that the lens contacts were dirty and to get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them.

Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera.

I did this to each of my three lenses just to be sure. Lo and behold, it worked



hope this works for you!!!! have a nice day!! :) :)

Cannon Eos 400D Err 99?


Error 99 is a NONSPECIFIC error message. It is almost always associated with the LENS. I first got this error on my EOS 20D whei I tried to use an older Sigma zoom lens (7 years older than the camera). I don't use off-brand lenses with my Canons. Try removing the main battery first followed by the time & date battery which is hidden in the battery compartment beside the main battery. This will reset your camera. Good Luck!

Error 99 in canon 400D


You will get that error when using some lenses other than Canon. A lot of the older Sigma lenses have that issue. Do you get this error when using newer Canon EOS lenses?
