Received this response from Canon. Good to get a quick response, but it seems kind of canned.
Thank you for contacting Canon product support. We value you as a Canon customer and appreciate the opportunity to assist you. I am sorry to hear that you are receiving an error 80 on your EOS 5D Mark III.
Lets try resetting your camera using the following steps to try and resolve this issue.
1. Turn the camera OFF and remove the memory card and battery first. Then detach the lens and place it out of the way. Use the camera body cap to prevent dust from getting inside and let the camera sit for 20 minutes.
2. In the interim please clean the lens contacts with a soft, lint free cloth. Use this to gently wipe the lens contacts. Sometimes the lens can lose contact with the camera if the contacts are dirty, so we want to be sure these are free from anything that could possible cause disruption.
3. Put these items back in the camera and turn the power switch to <OFF> and <ON> again.
4. Using the Mode Dial, change from Auto to Creative Zone modes and back testing each, to shoot and note if the issue persists.
5. Try a different Canon EF Series lens on the camera of any focal length.
Here are some other things to try:
- Use a totally different memory card.
- Are you in an area that has high humidly or cold temperatures? If so, move to a more suitable location.
If completing the above steps fail to resolve the issue then we recommend sending the camera into the Factory as we would be able to take a look at this product for you and see where the real issue lay. We very much apologize for any inconvenience this causes you at this time.
For factory service, please forward your digital camera to the Factory Service Center shown below. When shipping your camera, please be sure to remove the memory card and batteries. You are not required to send any accessories or manuals when shipping the camera. Be sure to include your name, street address (no P.O. boxes, please), telephone number, and a letter describing the issue with the product. If it has been less than one year since the camera was purchased, we ask that you also include proof of warranty in the form of a copy of your sales receipt.
As we do not provide RMA numbers for service, we suggest using a trackable and insurable service (i.e. UPS, Federal Express, Priority Mail) to ship your camera. Please package the camera very securely in a sturdy shipping box to prevent damage during shipment.
Please send your camera to the following Factory Service Center:
Canon Factory Service Center
100 Ridge Road
Jamesburg, NJ 08831
Upon arrival at the Factory Service Center, your camera will be logged in to our repair database and assigned a repair number. Next, the camera will be examined and you will be advised of the findings. If the required repairs are covered by the warranty, the repairs will begin immediately, and you will not be contacted. When the repairs are complete, the camera will be shipped back to you via Federal Express. The length of time for the repair will be dependent upon the nature of the repair and availability of parts, if needed. Usually, warranted repairs are completed within approximately ten to fourteen business days of the camera's arrival at the Factory Service Center.
All decisions regarding warranty coverage are made by the Factory Service Center at the time of repair. If the repair entails something that is not covered in warranty, a written estimate will be sent to you at the address that you have provided. The repairs to your camera will not begin until you approve this estimate and make payment arrangements. If, after receiving the estimate, you do not wish to have the camera repaired, please inform the Factory Service Center of your decision as soon as possible. If you decline the estimate, the camera will be shipped back to you unrepaired.
Once you have confirmed with your shipper that the camera has been delivered, you are more than welcome to contact us for repair updates. Please include your name, address, and telephone number, as well as the serial number of the camera, in all repair status inquiries.
Please note that our U.S. Factory Service Centers are unable to accept packages from or return equipment to addresses outside the United States. A signature will be required for the return delivery of your repaired product. For return shipping please provide a shipping address where an adult will be available to sign for the package.
