Error 99 lens shutter

if it is the 18-55 efs lens then you have a problem that there is a hairline crack in the diaphragm flexi. you can tell if the diaphragm of the lens does not open fully when not in operation. the diaphragm flexiboard assembly has to be replaced. usually not by the user.

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.

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

'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.

if you have a DSLR and your'e getting this "error 99" it may be associated with the particular lens youre using. try turning off the camera and removing the battery, the lens, and the memory card. let it sit for half an hour. reinsert the battery only and depress the shutter button as if you were to take a normal picture. if error 99 occurs again, then the camera needs servicing. if it error 99 doesn't occur at this point, turn the camera off and install the memory card. format the memory card while it's in the camera and press the shutter button as if youw ere to take a normal picture again. if you see error 99, then the problem probably lies with the memory card. if it doesn't occur, turn off the camera and install the lens. again, power on the camera and press the shutter as if you are taking a normal picture. if the error occurs, then it's with the lens. try to clean the lens including the connection points both on the camera and the lens. if the error code still occurs, try different lens to narrow it down to which particular lens is giving the issue. if it happends with all the lens, then the camera needs to be serviced.

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!! :) :)

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

Your camera performs a quick 'integrity' check before each shot and goes into error 99 mode if the lens in incompatible or has a diaphragm problem. ( it will also display e99 if the shutter or flash unit is not ok but this does not apply here ). This is how you can check whether the diaphragm mechanism is ok : attach lens to your old camera and set camera to AV and set F stop to 16 . open back and release shutter and look through the back to see if your lens is closing to F 16. If it is closing fine then the lens is ok but is not compatible with your D400.
