Canon BG-E21 Battery Grip (EOS6DMKII)

The grip balances the camera so well with a heavy lens that I barely notice the extra weight during a full day of handheld shooting. The vertical shutter button sits right where my thumb expects it, which makes portrait-orientation work feel completely natural now.

I take way more vertical shots now that the shutter button and dials are right where my fingers expect them. It fits snugly in my hand even with the 24-70mm lens and makes longer shoots feel less fatiguing.

I've been using this grip for a few weeks now, and the vertical shutter button placement is much more natural than I expected for portrait shots. The build quality feels solid, and it’s easier to get a secure hold with heavier lenses. Only minus is it makes the camera a bit heavier overall.
