Infamous error 99 (again!)

For the second time in just under a year my shutter has refused to work.
When i take a shot a hear a faint movement of the mirror but very weak. then all's black on the lcd (obviously) then the same old error 99 message.

The place I originally took the camera to in order to fix this the first time didnt know what to do so had a canon repair person pick it up themselves and take it off in which they (apparently) replaced the whole shutter system for a new one charging me 100 pounds. The warranty for this under the repair shop was only 6 months and since expired.
Looking through Canon's sites ive seen that all cameras are under warranty for a year after purchase, so shouldnt my 'brand new' shutter also come under the same warranty as it was installed by canon themselves?

I really cannot afford to have this fixed again so I am really desperate to get this fixed, I 've even read that it may be a case of a plastic pin that lifts the mirror inside that has been known to break on the 300 causing this problem,
but then I dont know?
Also Ive done all the obvoius things such as cleaning, and checking the battery etc and the problem is definatly the same as before.

Ive emailed Canon but have since heard nothing back and i cannot afford to speak to them for half hour on there premium number.

Re: infamous error 99 (again!)

Shutter mechanism of canon 300d lasts for around 5000 shots or less!! yes it is made of plastic materials thats why here in the philippines I am making my own metal replacement parts that lasts. Unfortunately, in your country you cant do anything but to replace it with same original replacement parts. avoid using faster shutter speed and continuous shots.

Blurry image with movement in the shot

This is common under low-light photography where the shutter needs to remain open longer.

A few tricks to help:
- Use the flash. Enable the fill-flash. This will work if the subject is close enough to the camera.
- Manually set the ISO to a higher number. Use the lowest number that yields good results as higher ISOs tend to also introduce some "noise" or graininess to the images. The higher ISOs will increase the sesitivty to light and compensating with a faster shutter speed. This is usually the easiest way.
- Manually increase the shutter speed. Try speeds starting at 1/250th of a second or faster as needed. Refer to your camera manual.
- Another technique is to pan with the movement. For example: If a person is running, follow them with the camera and carefully squeze the shutter release butten avoiding any camera shake. This can keep them in focus and blur the background instead. This is very cool, but takes some practice to master. The images look amazing and it is worth the effort.

Hope these tips help.

Error 99 message keeps popping up


I just read that the error 99 problem is a shutter failure and the shutter will have to be fixed. The cost is about $180.


ERR99 (error 99) is an indication that there is a communication problem in the camera. It is most often an indication that the shutter needs to be replaced, but it can be the result of other problems. All digital cameras occasionally need to have the shutters replaced. In the days of film cameras, it was rare to wear out a shutter because the cost of film and developing limited the number of times the shutter was cycled. With all those ones and zeros being considered "free" in digital cameras, it is not uncommon to take several hundred or more photos in a day. Even with a live-expectancy of 50.000 to 100,000 cycles, the shutters in digital cameras do reach the end of their life and need to be replaced.

Shutter replacement (usually associated with error code "99"):
  • Replacing the shutter on the Digital Rebel series requires more disassembly than most other repairs.
  • The estimate for shutter replacement is $180 on all EOS Digital Rebel models (depending upon the overall condition of the camera).
  • ERR99 error codes are related to shutter or mirror operation and are usually associated with a defective shutter. Cameras that have had heavy use may have shutters that have reached life expectancy and need to be replaced.

Codee error 99 ??


I do not know if this is going to be of any help. I was actually reading about this error code 99 in canon, and bumped into a forum, where people had share their experiences. You can give it a try. But if your camera is still under warranty, it is best to ring technical support.

"ERR 99" is a general error code displayed by the camera when the camera knows that something is not working properly, but not exactly what.

This error is typically associated with lens communication or shutter mechanism issues. To isolate the cause of the issue, we suggest that
you do the following:

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.

Hope this helps !!!

Shutter sticks

Does the light flash for 10 seconds, with a series of beeps getting faster before the picture is taken so you miss the shot, or are you saying the shutter stays open for several seconds giving you a whiteout picture?

If the former, then the self-timer is on. Press the button on the back of the camera to the right of the displays just under the AV button. The display icon will change from :-
Hand sweeping round clock = self timer mode
Simple square = single shot mode
Stacked squares = multi shot (keep finger pressed to keep shooting)

Canon error code 99

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.
