Love this!!!
2009-05-22This battery grip makes shooting for long periods of time (weddings) SO much easier and perfectly balances out the top-heavy feeling of a flash!

Heavy but necessary for steadier and quicker vertical photos
2009-03-13Warning: The BG-E4 may not be for everyone. It will be a pain to lug around all day with it attached to a 5D.
Battery grips completes a camera without a built in vertical shutter release button. I have it on a 5D mated to a light weight Canon EF 70-200mm f/4L IS USM lens.
I've had MB-12's on Nikon FE's, an MB-10 on a Nikon F90x, and a BG-E3 on a Canon Digital Rebel XT. All were necessary tools for me. The BG-E4 is no different. It's heavy at 2 pounds. But, without it, my vertically oriented photos lack a level of steadiness which affects composition.
Also, the BG-E4 is manufactured with magnesium alloy. That's why you pay more for the Canon grip.

Outstanding product
2009-03-11Ever since I got my 5D I have been thoroughly impressed with it, and this battery grip makes it perfect! I have big hands and this has helped a lot. Battery life is a plus and I love the portrait shutter button.
The first one I ordered from Canon malfunctioned, it would not allow a half-press shutter and would immediately take the photo instead. I called Canon and they told me to send it back for replacement. The 2nd one works perfect. Thank you to Amazon for such great service on the exchange!

Canon Battery grip for 5D
2008-12-28Works as I would expect. Went with Canon brand BG instead of aftermarket (as I did for my 10D). Amazon price actually was best price that's why I bought it here. If you own a 5D you need this, plus with the AA adapter and a set of AA's (I carry NiMH) in your bag you never have to worry about lost production time away from home.

It works since it was designed to !
2008-10-12What can I say, works great like it was designed to. Can't compare to the generic units out there but why would you skimp on a battery grip when you just spent $2500 on a camera like the 5d at the risk of a generic grip shorting out your camera and Canon won't warrant it.

What white balancing does is adjust the intensity of the colors being recorded according to the existing light.
