Camera Error

[USRanger]

Was out shooting today with my XTi and my 200-500 Tamron and it came up with 'Error 99'. I replaced battery and card and same error came up. I took it over to Mike Meyer's and he cleaned off the contacts, but that didn't work either. My other lenses work. Does anyone have an idea of what I need to do to fix the problem? Thanks!

Between you and Mike, you've taken a look at the most common easy solutions. I have some problems with my 70-200, particularly when the IS is on and also particularly when Steve is using it! A couple of other possibilities according to my understanding. Sometimes when my batteries are low, the problem gets worse so I'm careful to keep them as charged as possible when I'm using that lens. Also, calibrations or problems with the chip inside the lens could also be a factor. I'm going to be sending mine to Canon soon (before the wedding season starts) to see if they can come up with anything that can be corrected to eliminate the problem.

Must be a rash of these! Just helped somebody yesterday with this one. This is right from Canon support. Go through each of these steps and see if it helps. I've also had some success with re-loading the firmware. Its worth a shot. Just make sure you write down any custom functions you may have set, you will lose them. Good luck and let us know if this helps.

Thank you for contacting Canon product support.

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.

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.

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.

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.
