If you have had the camera from new for only 3 months send it back to the vendor or get onto Canon customer support for a replacement.

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.

SOURCE: Canon D40 Error code

Unfortunately, the ERR99 code is a catch-all code that means an UNKNOWN error has occurred. Because of this, it is going to be very difficult to pin down exactly what is causing the problem.

It could be a fault with either the camera (main circuit board, software, shutter mechanism etc.) or even the lens.

For starters, I would make sure that the lens electrical contacts are clean and the lens is mounted correctly and fully locked home. If you have a spare lens, try that also.

Next, I would reformat the memory card (do this in camera). If you have a spare memory card, try that also.

Check that the battery contacts are clean, and also the contacts of any external hardware such as vertical grips.

If none of these solve the problem, the only option left is to return the camera to Canon for a warranty repair, however if it is brand new, I would take it back to the store for an exchange.

Hope this helps,

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

I found this on the web. Maybe it will help. I have the same problem + left my camera in to be serviced.

Regards Ann

I have been experiencing sporatic error 99 messages for the past two months with my kit lens and my EF 75-300 f4-5.6 III. I have taken just over 7,000 exposures with my camera in 10 months. Last week was
my long awaited photo expedition to the San Juan Islands of Washington
State. Half way through the trip my Rebel refused to take any pictures.
I tried the obvious things but the error 99 message would not go away. It was consistantly making that partial , incomplete shutter trip noise.
I was actually relieved that it finally broke in the last two months of my
warranty so the repair would be covered. I salvaged the rest of the trip
with my Minolta D7 and got some amazing IR shots that I probably wouldn't
have otherwise. When I got back I called Canon and talked to Gary at 1-(800)828-4040. He asked me to try a few things before I sent the camera in. He said:
1. Carefully clean the 8 gold color lens contact pins on the camera body
lens mount with a pencil eraser. Do this while holding the camera so that
any eraser dust will not fall into the camera.

2. Take out both batteries. Yes, there are 2. I had forgotten about the
smaller Date/Time battery. Also remove the CF memory card.

3. With the batteries removed, turn the camera switch on for 3-5 minutes.
He said that this clears the memory.

4. Turn the camera off and put the batteries and CF card back in.

5. Re-attach the lens and turn it back on.

I did all of this and my camera works fine now. I had to re-enter the date
and time and re-select parameter 2 but my Rebel is now working again
and I'm much relieved that it was something that simple all along. Gary
was very courteous and knowlegable and waited patiently on the phone
while I went though his procedure. He said that I could send the camera
in for service if the problem came back. I just thought I would share this experience in case it might help someone else with an error 99 problem.

How to fix an error 99 on a Sigma 24-70 mm lens

The error 99 on your Canon is the last thing the camera can think of, if it really does not know what is wrong.
If you don't have the message when using a different lens, and the error keeps coming back with that lens, you are right it is in the lens. But again the camera can;t find out what.
The only thing you can do is make sure the contacts are clean and shiny and nothing os blocking free movement of all the parts on the lens. If you can't get it working correct, please contact a Certified Sigma service centre.

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

My Canon EOS XT continues to show error 99.


Err - 99 is one of the most frustrating messages a photographer can get because it basically means "there's something wrong, I'm not sure what it is, but something is definitely wrong". The error 99 code is a multi use code that Canon uses to alert you that there is a problem without specifics. I've gotten it on both my Canon bodies and each time I'd pull my battery and then replace it after a few moments and the problem resolved, but that is for me. I did notice that when I would get it my battery was usually getting flat. Once I cleaned the battery contacts on both bodies the error has not come back.

Some people have also gotten error 99 with a bad card, with a bad connection to a lens or grip but also to more serious problems, too.Your best bet is to take a pencil eraser and clean all your metal contacts (which you have already done) to see if it aleviates the problem. If you have more than one lens try changing lenses and see if you get it with all your lenses. Keep track of whether you get the error with all lenses or just one as it could be a lens that is causing the problem.

I notice that you removed the batteries. If you would try that again also pulling the card, but leave out for at least 20 minutes. This will give time for the capacitor to discharge all the electricity it's storing so that everything resets. Replace the battery only and test. If resolved then replace the card and test again.

Also clean your card and the slot compartment. You can do the card by wiping with a soft dry cloth and the compartment by using a card slot cleaner

If you are still getting an error it's time to have a repairman examine your camera body for further investigation.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Using a 70-300mm sigma lense on a canon 350d i error 99 flashes

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. They are an authorized service facility for Canon cameras. Also if you join they're facebook discount, they will give you 10% off the repair.
Here is the link to the facebook page, it has everything you need to send in your camera.

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!! :) :)

Error 99 for canon 350D

Error 99 says on the canon site to upgrade your firmware, so I did that, still no joy. Then i read on this site to clean the contacts between lens and camera with a soft eraser...worked a treat. No more err 99 and I will be keeping the rubber in my kit!!

Error 99 in canon 400D

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?

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.
