Hello Folks, I've been checking the internet to see the differences between these Grips GR-E1 and GR-E2. I've seen posts like there are some minor differences, but nobody is actually saying or noting what are those differences. Any Help will be appreciated! By the way, I checked with Canon technical dept, and daah! They didn?t know what I was talking about. I should have known better. The reason I'm asking is that I have some of these brand new Grips for over 5 years now, and trying to sell it on ebay, but have to know the difference before posting it on there.
