Question about Canon Digital Cameras

4 Answers

When I switch on my camera I get 'Err CF' on the display. According to the handbook I have to format the compact flash card - when it is formatted the menu will reappear - the menu does Not reappear bu 'Err 99' does. I have been on the internet and tried remedies suggested but nothing seems to work I am just being sent round and round in circles. My camera is a Canon EOS 20D, lens is a Canon Ultrasonic 75-300mm and my card is Sandisk Ultra ll 4GB

Things you can try:

  • clean the gold contacts of the memory card;
  • format the memory card through a computer using a memory card reader;
  • replace the memory card.
hope this helps.

Hi
To clear the "Err CF" error, try performing the following procedure.  1. Try using another CF card. 
If you have another CF card, try loading it in the camera. 
If the error code is not displayed when the other CF card is loaded, there may be something wrong with the first one rather than with the camera. 
2. Use your computer's ScanDisk utility to check the CF card for errors. 
Use ScanDisk to check the CF card for card error or card failure. 
Refer to the instruction manual for your operating system or Windows Help for further instructions. 
(If you are using a Macintosh, use the "Disk First Aid" program to check for card error or card failure. Refer to the instruction manual for your Macintosh OS for further information.) 

Be sure to back up the data on the CF card on the computer before you check the CF card. 

If a card error or card failure occurs when you use your computer's ScanDisk, there is something wrong with the CF card. 
Follow ScanDisk's on-screen instructions to solve the problem. 

If the same error occurs when you are using the CF card supplied with the camera, please contact the retailer where you purchased the camera or the nearest Canon service center. 
If the error code is displayed right after you took a picture, the image may not have been recorded. Switch the camera to playback mode to check if it was recorded. 

Precautions for handling a CF card: 
- Do not remove a CF card or disconnect the camera's power source while the camera is recording, loading, or erasing data on a CF card.
- CF cards are high-precision electronic devices. Do not bend, force, or subject them to shocks or vibration. 
- Do not attempt to disassemble or alter a CF card.
- Place the CF card in the supplied case for storage.
- Moving a CF card rapidly between temperature extremes may cause condensation in the card, leading to potential malfunctions. To avoid condensation, place the CF card in a sealed plastic bag before moving it into a different temperature area and allow it to adjust slowly to the new temperature. If condensation forms on the CF card, put it aside until the water droplets have evaporated completely.
- Do not use or store CF cards in the locations subject to dust or sand, high humidity, or high temperatures.

    error
    99 is usually a 'catch all' from what I know. It can be anything from a
    faulty card, to a dirty contact on your lens. I would check the
    contacts to make sure they are clean.



    If you want more info on the 'error99' I would suggest checking out
    http://www.dpreview.com
    in the 1D fourm. Just do a search.

    One more reason could be

    Dirty lens contacts will also cause ERR99

    The coin battery *should *be changed as well. They start out at a bit

    over 3V, and

    typical useful life in the 350D is 3 years.

HI,

clean the CF contacts inside the camera. If it started after a few months, and formatting the CF in your camera didn't fix it, I guess it should be a faulty CF (or a faulty camera, ouch!). To double check you can borrow a CF and try it in your camera. If the latter works, then reach you re-seller or Sandisk to have the CF replaced.

    To isolate the cause of the issue, I 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

Err CF I have a Canon Rebel XT, how do i fix this error and what does it mean?


CF stands for compact flash which means you have an error with your memory card. Try removing and replacing your compact flash memory card. If that doesn't work you may need to format your memory card or replace it.

When isert flash card i get err2 sign


According with the manual:

Err 02: There is a problem with the CF card. Do one of the following: Remove and reload the CF card, use another CF card, or format the CF card.


Try formatting the CF card in the camera, if that doesn't work use a card reader to format it in your PC then format it again in the camera. If that doesn't work try a different CF card.

Keep us updated.

I have a CF err on my Canon Rebel XTI EOS


If your camera uses a compact flash card, then something is wrong with it. Possible causes: card needs formatting in camera (this will erase it) one or more pins inside camera are bent. Card was erased or formatted on computer instead of camera.

I had this exact problem. What I needed to do was first, turn on the camera with it set in the photo taking mode. Next, in the menu system, select "Format". This will format the CF card to work with the camera. Hopefully this will help!

Canon 5d cannot format cf care


Hi there, did you check the card itself? SD cards have a locking switch on the side. Move the switch from locked to unlocked. Put it back in the camera and see if that helps.

Nikon D70, displaying error code 'CHA' when memory card inserted. Unable to format or use memory card. Have tried new memory card, still same problem.


CHA errors indicate a communication issue with the CF card. Your card could be going bad, you could have a broken pin, or any number of other problems.

I'm running into this same problem now. If anyone has a good step-by-step to troubleshoot which of the dozen things this error could be, I'd appreciate it.

For myself, I'm planning to start by trying a new CF card.

Canon camera has error cf


Of course you have tried to format the CF card ? That can solve the problem.

If you get err 99 when trying to format the memory card, the problem is probably in CF (Compact Flash) connector. One common reason is bent pin. You can see it when looking into card slot.

Another possibility could be the CF connector terminations inside the camera. I repaired one EOS 350D where solder joint in one of the pins (23rd) was broken. And that looked like manufacturing failure in the printed circuit board (see the picture). The solder pad for that pin was far too small. There can be also other such cases in the market. The disassembly of the camera is rather difficult but if you have some experience on that kind of work, it is worth trying when you have no other option. Some guidance for disassembly can be found for example here: http://astro.ai-software.com/articles/mod_350D/mod_350D.html
