Mcoplus Professional Vertical Battery Grip Extension for Sony A7III A9

In this review the Mcoplus Professional Vertical Battery Grip Extension is assessed as a practical and affordable VG-C3EM replacement for Sony A9, A7III and A7RIII shooters who need longer runtime and improved handling for portrait work. It delivers the obvious win: support for one or two NP-FZ100 batteries so photographers get extended shooting time, and a full set of vertical controls that mimic horizontal operation. For photographers who shoot outdoors or use telephoto lenses, the grip adds stability and a comfortable rubber-coated hold while keeping the camera balanced.

Key Features

• Compatibility: Designed to fit Sony A9, A7III and A7RIII cameras and function as a VG-C3EM-style replacement for seamless integration.
• Vertical shooting controls: Built-in vertical-grip shutter button, front and rear dials, AF-ON and AE-L buttons plus multi-selector provide a familiar control layout for portrait orientation.
• Double power: Accepts one or two NP-FZ100 batteries to extend shooting sessions without swapping packs, useful for long outdoor shoots and events.
• Improved stability: The rubber-coated surface and added weight give a better hand feel and help balance heavy lenses for steadier results.
• Tripod friendly: Includes a standard 1/4 screw hole so the camera and grip can be mounted quickly on most tripods.

Who It's For

The grip is ideal for photographers who already own a Sony A9, A7III or A7RIII and want reliable extra battery life and a proper vertical control set for portrait sessions. Wedding, event, and wildlife shooters who need longer runtime and better balance with telephoto lenses will find the double-battery option especially useful.

This is less necessary for casual users who rarely shoot vertically or who prefer to swap batteries in-camera. Also, those seeking full manufacturer warranty parity or factory-original accessories should compare official options, since this is a third-party replacement aimed at value-conscious buyers.
