Error 99 Canon 30D

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.

Error 99 is common error on Canon cameras. Make sure the battery is freshly charged. Take the battery out, the compact flash card out, and the attached lens off of the camera. Leave the camera set for a while for the capacitors to bleed off. Around a half hour would be good. Next re-insert the battery and push the shutter button as if you were taking a picture. If you get an Error 99 then, you can't fix the trouble and Canon will have to do it. If you do not get an error 99, power the camera off, insert the compact flash card, power the camera back on and press the shutter button again. If you get an Error 99, the trouble is in the compact flash card or its connector. Try a different card. If you do not get an Error 99, power the camera off, a lens on it, power the camera back up, then press the shutter button once again. If you do not see an Error 99, the problem is no longer in the camera. If you do see an Error 99, power the camera off and remove the lens. The problem is probably in the contacts on the camera or the lens. Clean the contacts by holding the camera carefully with the lens opening down so it will not allow dirt to get inside the camera. Take a cotton swab dipped in alcohol and clean the gold metal contacts well, Dry the contacts with a tissue. Next hold the lens with the contacts down and repeat the process on the contacts on the lens. Be very cautious not to allow lint, dust, or alcohol to get into the camera body or into the lens. Some people use a pencil eraser to clean the contacts but you have be very careful not to let particles enter the camera or lens. This should clear your trouble, if the camera passed the first step of troubleshooting.

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.
Thanks

Error 99 is Canon's default for several "connection" problems most common are dirty contacts between the lens and camera body. Another is the contacts in the battery compartment both the camera and the battery contacts should be cleaned.

The camera might not be able to read the memory card, download the pictures to your computer and format the memory card don't delete them format the card this function is found in the set up menu.

Formatting is one of the most important functions to keep the camera and memory card communicating AND is the most neglected function. Always format a new memory card and always format a memory card after downloading pictures to a computer. Format a memory card if it's been in another camera.

Cleaning the lens and body contacts can be done fairly easily with a clean pencil eraser, don't use a puffer on the body as you will blow dirt into the camera. With the lens removed hold the camera as much as possible with the lens opening pointed down and gently polish the gold contacts. Do the same with the lens contacts make sure both areas are clean and re install the lens to the body.

Possibly the most important "fix" is to update your camera's firmware. Go to Canon's web site (it can be a bit intimidating at first) and search through until you find the firmware updates for your camera. Download this generally they want you to download to a memory card then place the card into the camera and upload the new firmware updates.

The Canon 30D (in my opinion) is one of the best no frills, greatest working DSLR cameras Canon produced. Not saying the model's beyond are not it's just the 30D isn't loaded down with video functions. Great all around working camera, sorry my rant for the day.

Cheers have fun with your Canon 30D

Hi,

Can you replicate this fault on other lenses? Is it is only on the 17-85 lens try cleaning the lens contacts with a pencil eraser and see if it helps.

'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 is moisture or dew inside the camera.

See if Sigma has any updated advice on this. Otherwise, I don't mean to sound rude or harsh, but unfortunately you may be out of luck with the compatibility...you will need to get a Canon lens. Error 99 is just a communication error and cleaning the contacts is about all you can really do so if that hasn't worked...I'm sure this is not the news you want to hear, but contact Sigma if you haven't already and see what they say.

Take care!

Had this problem before and i found this guide online

1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99′ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is
attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the
camera should be serviced.

Error 99 is a general fatal error.
which includes the problems above mentioned by Q4SteveB but also many others.

It can be caused by a dicky shutter, problems with the CF card interface.

If cleaning and trying a different lens has not worked. Not definitive but as a rule of thumb...
If it letting you take one picture then giving error 99.. and the picture is saved to the card (but may just be black) this is most likely the shutter needs replacing..

If it takes a picture and gives error 99 but there is no picture on the card or the picture is 0KB its a CF interface problem.

If you get an error 99 when you plug in the USB its a USB interface error, you can try a different cable but unfortunately in most cases if another lens or cable wont work it needs repair
