I am having a similar problem with my Canon 20D. Today I narrowed it down some. It does not appear to be a camera problem, it appears to be a lens problem. My Canon EF-S 17-85mm lens seems to be having all the problems, but when I change to my other lens everything is fine. That lens has gotten worse, to the point where today I was almost unable to use it at all. Wide angle shots only!

So I hope that helps. Now to figure out what's wrong with my lens and how to get it repaired...

I have faced similar problems previously with my Canon 20d and Sigma 170-500. Its even more annoying to see it happen in field while it would be okay back home. I was told that it is electronic compatibility problem instead of complaining the best was to change the lens and hence bought a 100-400 and happy ending.

Error 99 with a Canon 300D (original rebel) and Tamron XR Di II 18 to 200 mm lens. Occurs when lens is zoomed out. Does not happen with other lenses (Canon 18-55 kit, Canon 75-300). Cleaning contacts on...


Welcome to Fixya
Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.

Thank you for using Fixya!

I have a tamron 70-300mm i had a canon 1000d and the lens worked pefectly fine with it but nw i hav purchased canon 550d and when i conect my tamron lens with it , it shows an error 01 please assist me


This is the kind of error which you always risk these days in buying lenses which are not from your camera manufacturer. Error 01 simply means that the camera cannot communicate with the lens. Canon's protocols are not open standards and third party manufacturers have to reverse engineer to produce something which works. As they're working in the dark, they cannot always arrive at a solution which makes all models suit all Canon bodies.

You have two possible solutions:-

Visually inspect the contacts on the lens and the camera body and if they're anything other than clean and bright then use a clean pencil eraser on them. Be very, very, careful not to let any of the rubber crumbs into the lens or the camera body.

If that fails, visit the Tamron website to see whether the lens can be returned to be updated for other bodies. if it can't then sell it and buy a later Tamron model or better still a Canon one. They may cost more, but the results are better and their resale value is much higher.

Canon 30d with tamron af 70-300mm di macro lense showing error 99


'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. Alternately, it can also be a card error or camera error.

First remove the lens, battery and card and leave the camera like that for about 30 min. After that, insert a fully charged battery and switch on the camera. If the error still shows up, it is a fault with the camera and has to be serviced.
If not, turn the camera off and insert the card. Format the card in the camera and depress the shutter button. If it shows an error, the card is faulty.

If not,
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 error still shows up, you need to take the lens to an authorized service center.

Err 99 with canon 350d


Hi,
This error may be displayed if you use a non-Canon lens and the camera or the lens does not operate properly. Remove the battery and re-install it. If the problem persists, get your camera / lens checked by a qualified technician.

Hope this works. Thanks.

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.
