Canon 5D Mark II Battery Grips: BG-E6 vs. Third-Party Grips
14 January 2010
Excerpt: The Canon BG-E6 battery grip serves a couple of different purposes for the 5D Mark II . As the name implies, it holds batteries – either two LP-E6 lithium-ion batteries or 6 AA batteries in the included battery holder. Likewise, the BG-E6 serves as a grip for handling the camera in portrait orientation, featuring controls for the shutter release, scroll wheel, and focus point adjustments, among others.
Excerpt: The nice thing about Canon DSLRs without a built-in portrait/vertical grip (all non-1-Series bodies at this time) is that they are small and light. The big downside is that it is not comfortable to shoot in portrait/vertical orientation - especially for long periods of time. Thus, Canon makes Battery Grips for all of their non-1-Series batteries.
