I hope this web page helps people. I really do. I hate not knowing stuff, and because of this lack of knowledge something valuable to me may end up damaged, suck money out of my wallet or waste my time. I hope this article saves someone out there some grief!

I have used my Canon 5Dmk2 twice. Once to shoot a movie called “Burial Site” and the second time to snap off a few RAW stills while hiking in the White Mountains of New Hampshire. Things went well, I got the camera a little wet while hiking, but everything checked out fine.

I tried to use it for the third time and now the camera is a paperweight. NICE!

This has nothing to do with the light rain that I was shooting in while hiking in the mountains. It was something else all together. I slid the Kingston Compact Flash memory card into the socket on the Canon 5Dmk2 and found the camera to be malfunctioning. Nothing out of the ordinary, the card went in fine. The camera took about ten seconds to fully power up and it displayed the words, “Card Must Be Formatted” on the LCD.

I was surprised at this, so I went into the menu and selected “FORMAT”. Instantly, the camera stated on the viewfinder, “CARD CANNOT BE FORMATTED”.

CF card tight

I removed the card and looked at it. I noticed a slight indentation between two of the holes in the interface. I immediately thought that one of the pins in the camera must have bent and that was the cause of the mark. I did not force the card into the camera, I just pushed it in like I had done in the past.

Next, I grabbed a flashlight and a magnifying glass and looked into the CF interface cavity of the 5dmk2. I saw that one of the center pins was pushed down into the socket. I swore.

Putting in the CF card

That is pretty much it. If you own this camera, be careful! I did nothing wrong. I did not insert the card incorrectly. I simply ejected it, used it in a external memory card reader and then reinserted it into the Canon camera. The CF card was carried inside the little plastic case so that it would stay clean. I tested the suspect CF card in my external reader and it works fine. I cannot explain why this happened, but I will be contacting Canon tomorrow and I plan to add updates to this page as I go through the repair process.

July 6, 2009 @11am – Called Adorama in NY at 800-223-2500. They told me to call 800-OK-CANON. Called Canon, they told me to call the service center in New Jersey at (732) 521-7007. I waited on hold for twenty minutes and when call was answered I was told I was in wrong department. The guy then told me that there was a long wait for repair. I told him I had been on hold for twenty minutes already. He said, then try registering for repair on Canon’s web site at http://www.usa.canon.com/repair. I am now trying that.

July 6, 2009 @11:15am – I have submitted a new repair request through the Canon website. I filled out all the info and this is what I posted when asked to explain the problem.

July 6, 2009 @2pm – I have packed up the camera and placed it in a small pelican case. I placed the peli-case inside a slightly larger box and sent if to the Canon Service Center in Jamesburg, New Jersey. It is due to arrive tomorrow.

Inserted a Compact Flash card into Canon 5D mark 2 for just the third time and powered up the camera, the camera did not initialize. Camera LCD stated that the “CARD MUST BE FORMATTED”. The card was already formatted.
I looked at the card and there was a mark between two of the contact holes.
I looked into CF camera cavity and found that one of the center pins in the interface was bent.
Camera will not format or recognize the CF card.
I posted pictures to my blog that might help you understand the situation better.

July 15 2009 @1pm – Fed EX arrived at my home with Canon Package
I was not charged any money for the repair. The repair took just 12 days from the time of damage to the time of repair delivery.

The paper included with my repaired 5dmk2 stated:


Canon also added:

We have examined the product according to your request and upon close inspection the exact cause could not be identified but it was found that the memory card slot pins were broken. The internal component was replaced. Other electrical adjustments, inspection and cleaning and parts replacements were carried out. REPLACED MAIN PCB ASS’Y.

I hope this helps you if you are going through the same inconvenience. I have replaced my Kingston Compact Flash cards with Sandisk Extreme III cards. I am not sure if the camera had a bad pin from the factory or if my Kingston cards were to blame.

Based on what I have gotten back in writing from Canon, it appears that you get a one time “courtesy repair” on the PCB assembly. Not sure how much it will cost me if this happens again.
