Question about Canon EF-S 17-85MM F/4-5.6 IS USM Lens

1 Answer

I have not banged or dropped my EFS 17 to 85mm lens that I know of but today I got an Error 99 and now the lens is very dark when I look through the viewfinder. I cannot take a picture. I know that the issue is with the lens, as I have another lens that works fine and can take pictures. It seemed to get worse from hard to focus to dead withtin the space of a few shots. Any ideas?

Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

I am using a canon 350d camera. when I use my efs 18-55mm lense there is an Error 99. Is there a problem with my camera or lense and how can I correct it myself or i need to get professional help. Thank...


'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.

Try and fit Canon EFS Lens to EOS 5D Body


As far as I know, you should use L series Lens to fit Full Frame Canon Camera (5D & 1D).

That would be no adapter, but please correct me if I'm wrong.

ERROR 99


Error 99 is a generic error in that the camera does not know what the exact error is. The usual fix for this error is ......

Turn the camera off and remove the battery.

Remove the lens and clean the electrical contacts on the rear of the lens with a soft dry cloth.

Refit the lens and the battery and switch back on. Hopefully all will be well again.

Canon EFS Lens question- please help!!


Make sure that the switch on the lens is set to AF. If that doesn't work, you may have a faulty lens. The EFS 18-55 is not a high quality lens.

Error 99 only when flash pops up


I know what you two are talking about. I ordered a Canon EOS 300d from a site called "Keh" and I had never used one before... so I get it in the mail on time. The camera works fine for a few minutes then I get an "error 99" and can't do jack with the camera. I researched online and even called keh ... I read and heard that it has to do with the lens... so I sen't the camera back and got my money.
