I'm not that bothered about the new battery for the 5D2, and how each one has a chip in it that helps the camera ID it. However, I did wonder if it will stop 3rd party batteries appearing?
I was just wondering if this was a ploy for Canon to make more money on batteries by only allowing official batteries to have the ID chip, thereby meaning you have to by full price batteries to be able to use the whole which battery has how much charge, when you last charged it, how many shots it took, etc.
:p
