'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.

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

Hi there I have recntly purchased a Canon 15m EF fish eye lense which I have used on a Canon 450d + 350d body. On the 350d I get an error 99 code and on the 450d get a 01 error code. This leads me...


Rob, Error 99 is Canon's catch all error code, yes my first impression would also have been to clean the contacts but something else that is happening is the camera firmware may need to be updated to handle that particular lens. Camera updates are free on the Canon site and actually can solve a lot of hidden processing problems.

That lens isn't really suitable for your 450d as it's an APS-C sensor size with a 1.6 crop focal factor which will give you more like a 24mm focal length.

You may also want to format the memory card and clean your battery terminals both the battery and the contacts in the battery compartment.

Best little cleaning item for cleaning contacts is a pencil eraser (new) lens contacts or battery something about the soft rubber cleaning off the most suborn dirt and electrolysis.

Don't use a "used" eraser obviously it will transfer the dirt to the contacts over removing what you want.

Hope these techniques work they have for me

I was wondering if lenses from a Canon 35mm camera will work with this camera?


When choosing a lens for your Digital Rebel XT, look for EF or EF-S on the lens. Film lenses with the EF designation will work on your digital camera, but AF or older lenses will not fit. Trying to force them on may damage your camera.
When using a film lens on a digital camera, there will be a 1.6x conversion factor. This means that a 50mm lens will be closer to a 70mm lens in reality.

I dropped the lens and now get error 99 when trying to use it.


Probably cracked an internal circuit board on the lens- not an item you can easily repair yourself

Error 99 usually refers to a shutter error with the camera. It is most likely not your lens, but you can try it on another body just to be certain. Try PhotoTech Repair Service, in NYC.

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!! :) :)

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?
