    when i shoot with the lens at 17 i dont have a problem. when i zoom to any other number i get a error 99  ,80% of the time

    i have the same problem when using a 17 - 85 EF lens with my.20D.
    The most annoying thing is that it has been fine for a couple of years and i never had any problems until i took it on holiday with me...so i missed out some potentially good shots.

I experienced the same problem ( Err 99) on similar set-up after taking around 9000 shots. I have read solutions from upgrading firmware to 2.0.3 and extensively cleaning the gold contacts on the camera and the lens with alcohol. Since my firmware is already ok, then I think the cleaning did the thing.. my camera does not randomly give the error anymore!

Assuming that other lenses function normally on the camera, the "Err 99" can be caused by a failure of the aperture component in the lens. Error 99 is a generic error, so unfortunately it does not indicate exactly what is wrong. There are other factors that can cause the failure, but there is a good chance that the aperture is not functioning correctly. You can try cleaning the electrical contacts on the lens, if this does not work you may need to get the lens serviced. Check with Canon, or check the web for other repair service providers.

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.

Will a SIGMA 70-300 f4 DL MACRO LENS fit on a CANON EOS 20D?
Assuming you get the lens with a Canon mount, yes. Sigma makes lenses to fit a variety of makes, but each one has a different mount. A lens intended for a Nikon, for example, will not fit a Canon.

I got error 099, before I was getting error 05. and the flash dos not open canon EOS 20D
I also get the error 99 message and cannot take any photos... I have been able to solve this problem by taking out the batterys and wiping down the connectors on both the batterys and the connecters in the motordrive with a lens cloth. keep the lens cloth on hand when shooting. It may be that either oils, or dirt has gotten onto the connectors. I hope this helps.

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!! :) :)

Canon eos 20d giving false error message
CF means that it can't read the compact flash socket on the side. I had a similar problem on one of my bodies. I would try either a different (new or one that hasn't been in the body) with a freshly charged battery. If this doesn't help, you can only send it in for diagnostics and repair

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?
