Promaster BG-E11 Battery Grip for Canon EOS 5D Mark III, 5DS, & 5DS R

ProMaster BG-E11 Vertical Battery Grip

Professional Ergonomics and Extended Power at an Accessible Price

For professional portrait, wedding, and event photographers using the classic Canon EOS 5D Mark III, 5DS, or 5DS R, adding a vertical battery grip is often a mandatory upgrade. However, original manufacturer grips can be prohibitively expensive. The ProMaster BG-E11 Vertical Battery Grip offers the perfect solution. As a high-quality, dedicated third-party alternative, it completely transforms the camera's ergonomics and dramatically extends its shooting life without breaking your accessory budget.

By adding a substantial, comfortable grip for vertical (portrait) orientation shooting and mirroring the camera's core physical controls, it completely eliminates the awkward, fatiguing posture associated with holding a heavy DSLR sideways. Whether you are shooting a 12-hour wedding or tracking wildlife in the field with a massive telephoto lens, the ProMaster BG-E11 ensures you have the power, balance, and stability to keep shooting without interruption.

Why You'll Love This Grip

• A Budget-Friendly Alternative: Get all the functional benefits of a professional vertical battery grip at a fraction of the cost of the original equipment manufacturer (OEM) version. It is an exceptional value for enthusiasts and working professionals looking to maximize their equipment budget.

• Double Your Battery Life: The grip houses up to two Canon LP-E6, LP-E6N, or compatible third-party high-capacity batteries. This effectively doubles your shooting time and video recording limits without needing to pause the action to swap power, drastically reducing the number of shots lost due to dead batteries.

• Flawless Vertical Ergonomics: Shooting portraits is effortless. The grip provides a deep, comfortable hold that perfectly matches the contours of the camera body. It shifts the center of gravity downward, which is especially helpful for balancing heavy, front-weighted telephoto lenses.

• Mirrored Tactile Controls: You do not lose any functionality when shooting vertically. The grip features a duplicate shutter release button, main dial, multi-controller joystick, AF point selection button, AE lock/FE lock button, and AF start button, all placed exactly where your fingers expect them to be.

• AA Battery Compatibility: Included with the grip is a dedicated AA battery magazine. In an absolute emergency where you cannot recharge your lithium-ion batteries, this tray allows you to power the camera using six universally available AA batteries.

Technical Specifications

Things to Note

First and foremost, it is important to understand that this is a third-party accessory manufactured by ProMaster, not by Canon. While it is engineered to closely mimic the fit, feel, and functionality of the official Canon BG-E11, it does not feature the exact same magnesium-alloy construction or rigorous weather-sealing of the OEM version.

Secondly, please remember that batteries are sold separately. The grip does not include any lithium-ion batteries in the box, so you will need to purchase an additional LP-E6 style battery if you want to utilize its dual-slot capacity right away.

Just like the original version, you must verify your exact camera model. This grip fits only the EOS 5D Mark III, 5DS, and 5DS R. It will not fit into the older 5D Mark II or the newer 5D Mark IV.

Finally, to install the grip, you must physically remove the battery door from your camera body. ProMaster has included a clever, hidden storage slot directly on the vertical grip's connection post where you can securely stash your camera's battery door so you don't lose it while the grip is attached.
