I'm thinking of getting a grip or two for my cameras. 5DII and 7D.
As of right now carrying 2 cameras + 2 flashes + 2 lenses (17-40 + 70-200 2.8 IS) + think tank belt systems with additional lenses, batteries, water bottle and snacks, during a wedding is already starting to give me pain (hands, back, shoulder).
But I like the portrait orientation of using a grip and how it feels in my hand. I have a big hand.
how much more weight does a grip for either one (5d2 or 7d) + batteries would weigh?
Does a third party grip weigh less than Canon's?
