During the past couple of months of using my Canon 7D, I kept on getting these random ‘Err 02’ message and then to lose the video clip/photo I was trying to capture. Yea, I thought it might have been for the super over-hyped Sandisk CF Cards I’m using but my false accusations have been put to rest as it turns out that there’s a fix for the ‘Err 02’ message (and other phenomenons) via a firmware update released by Canon. Well, it’s somewhat official; Canon did release it out to the masses then plugged the hole up. Fortunately, our good friends over at CanonRumors.com (http://www.canonrumors.com/2011/04/firmware-1-2-5-for-eos-7d/) have the file and are hosting the download.
I’ve just recently updated my camera and so far I can tell you that I haven’t bricked it. As for the ‘Err 02’ message, only time will tell.
Oh, just in case if you don’t know how to update your camera’s firmware… http://web.canon.jp/imaging/eosd/firm-e/eos7d/firmware.html
