Battery Grip EOS 50D: Battery grip BG-E2N with Battery Magazine BGM-E2
This optional grip is the same as the EOS 40D’s, and was designed to extend shooting capacity and enable vertical shooting. Constructed out of magnesium alloy with weather and dust resistant seals around the battery compartment, the grip includes a vertical shutter button, auxiliary main input dial, AF point selector button and DC coupler cord mount. With batteries loaded, the grip adds heft and
overall balance that is closer to that of the EOS-1Ds Mark III body. There are two power choices: it can be loaded with either one or two BP-511A lithium-ion Battery Packs or with six AA-size batteries (using the included battery magazine). When loaded with two BP-511A Battery Packs, normal shooting capacity doubles to approximately 1,200 shots (at 50% with built-in flash, at 73 degrees F operating temperature) or up to 340 shots in Live View shooting mode.
EOS 5D Mark II: Battery Grip BG-E6 with battery magazine BGM-E6
Exclusively for the EOS 5D Mark II, the new BG-E6 features a magnesium alloy body and sealed battery compartment that complements the ruggedness of the EOS 5D Mark II, as well as extending the camera’s versatility and shooting capacity. It provides a comfortable grip and array of controls for shooting in vertical
orientation, as well as two power options: either one or two LP-E6 lithium-ion Battery Packs, or six AA-size alkaline batteries. When loaded with dual LP-E6 lithium-ion Battery Packs, detailed battery information and recharge performance is communicated to the camera, and shooting capacity is doubled, to roughly 1,700 shots
(at 73 degrees F), or approximately 400 shots when using Live View shooting mode.
