Battery Grips on Mirrorless Cameras: When the Extra Weight Is Worth It and When It Isn't
Mirrorless cameras were supposed to be small. Then photographers started bolting battery grips under them, and many pro bodies now look as big as the cameras they replaced. It’s a fair question whether a grip still makes sense when the whole point of the format was to lose bulk.
The answer depends on what you shoot, and for how long. For some people a grip is the best accessory they own. For others it turns a nice small camera into a brick.
The photographer below shows why sport and wildlife shooters keep using them. Eye pressed to the viewfinder, a heavy white telephoto out front and a gripped body behind it. With a big lens, the grip gives the right hand somewhere to go.
What a grip actually does
Three things. It roughly doubles battery life by holding a second battery. It adds a second set of controls for shooting vertical, with its own shutter button, dials and often a joystick, so you can turn the camera on its side without twisting your wrist up over your head. And it makes the camera bigger and heavier, which balances big lenses better.
Some grips add extras on top: an Ethernet port or a cooling fan for video on certain high-end bodies. Check what yours does before assuming.
Who should buy one
Wedding and portrait photographers. Weddings run ten hours or more, and half of all portraits are vertical. A grip’s vertical controls save your right arm, and the extra battery means one less swap during the ceremony.
Sports and wildlife shooters with heavy lenses. A 70-200mm f/2.8 or a 600mm zoom tips a small body forward. A grip gives you a full hand hold and makes the whole thing balance better on your left hand under the lens. Long bursts at 20 to 30 frames per second drain batteries fast, too.
Video shooters on long takes. Mirrorless cameras burn through batteries recording 4K. A grip, or better still USB-C power from a big battery pack, keeps a camera rolling through a full talk.
Who shouldn’t
Travel and street photographers. You bought a small camera for a reason. A grip adds a few hundred grams and makes it harder to carry in a small bag. Carry a spare battery in your pocket instead.
Owners of compact bodies. Many small cameras, such as the Sony A7C II and Canon EOS R8, don’t have a battery grip at all. Third-party L-brackets with an extended base can improve handling without the weight.
Anyone using small primes. A grip under a 50mm f/1.8 is all camera and no lens.
The alternative: built-in grips
Some flagships build the vertical grip into the body: Canon’s EOS R1 and EOS R3 and Nikon’s Z9. They’re tougher and better sealed than a bolt-on grip, with no join to flex or leak. They’re also big, permanently.
For most enthusiasts, the smarter choice is a body like the Nikon Z8 or Canon EOS R5 Mark II that takes an optional grip. Fit it for the wedding or the air show. Take it off for the holiday.
Buy the official one
Third-party grips are much cheaper, and some are fine. Others have loose fits, flaky contacts or weather sealing that isn’t. On a camera you depend on for paid work, the brand-name grip is worth the price. For hobby use, a well-reviewed third-party grip saves real money.
