Steven, good god - sell all you gear and buy a nikon. Just don't EVER open it up because they use the same kind of shielding in several places as well. This was already pointed out. Great, you build computers, congrats - do you frequently take apart laptops? Apparently not. I have ZERO credentials to spout, I'm not an engineer, but I am a dumb tinkerer, and this is not surprising to me in the least. I do, however, own a 5D Mark III, and I'm not in the least bit bothered by this fix. I DID shell out $3500. According to your signature, you don't even own a 5d3, so what the hell are you so worked up about?
