SOURCE: Error 99 Code on 5 month old Canon 40D

error 99 can be several things. Try the following. Check that the contacts on the lens housing are clean if not clean them with a swab of denatured alcohol available at walmart. also if there is extremely cold weather your shutter could be creating the error. Try using a blow dryer and on the warm setting warm up the camera with the lens off. Blow around the mirror area. I know it sounds silly but it has worked in the past. Good luck.

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

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.

Have you actually cleaned the contacts or are you just looking at them and they "look" clean? Clean them with a cotton swab lightly dampened in rubbing alcohol.

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 would get a card reader to connect the card to the computer. For the future, it will save wear and tear on your camera and doesn't use up the camera's batteries. You can find them at any large store, such as Walmart or Target. Here's a link to one on Amazon: Kingston 19-in-1 USB 2.0 Flash Memory Card Reader I hope this helps! Happy Shooting!

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 dropped my canon rebel xsi from about 7feet, but it still took pictures after i checked it. nothing cracked, not the lense, or the screen. but than about an hour later, when i tried taking pictures it...


It could be several problems. One is a bad contact between lens and camera body, clean the contacts , check for damage and try another lens if you have one. Try another memory card. Another problem could be with the shutter which would need the camera to be repaired by canon.

Sony cybershot 7.2 went to shut off camera and lense is still out no power to camera tried to recharge batt. w/no results


Try different batteries. I got the same problem with my cyber-shot. The battery was too low while lense was fully open. I recharged, but the lense would not close. When I turn it on, It would say turn off and on again. I did that for at least 20 times. I finally put another set of batteries and while I turned off the camera, I pressed the lense in very softly. After a couple of times the lense retracted fully. The camera has been working normally ever since.

It is also possible some dirt some how got on the sides of your lense. Try cleaning the sides of the lense.

If you had no luck so far, then your lense may have some mechanical problem. The lense need to be opened and cleaned and put back together.
good luck

My Canon is displaying - Err 99 what should I do?


This can mean a host of different problems but try these things to fix it:
  1. clean the lense contacts as poor conection between the camera and the lenses can cause this. Also clean the contacts on the body of the camera.  The contacts should be cleaned with a plastic eraser, but make sure it is clean before using it.
  2. Clean the battery contacts (on the battery)
  3. Change lenses and see if you have the same problem (does it only have this problem on one lense?)
  4. Make sure you have the lates firmware installed.
Don't swap lenses while the camera is writing to the memory card, lots of things like this can cause this error message. Also the flash can cause it.
Usually the lense is the culprit so make sure it is fully cleaned.
Cheers

Error 99


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.
