5D Mark IV - Really Right Stuff Base Plate

Arca-Type Compatible Dovetail Mount for 5D Mark IV

Dedicated to the Canon EOS 5D Mark IV DSLR, the B5DMkIV Base Plate from Really Right Stuff is an Arca-type compatible plate that facilitates easier, more stable mounting of your camera atop a tripod. This plate features a modular design that allows it to accept an optional L-component, which combine to form a dedicated L-plate. The custom-fit design also maintains full access to the battery door and features two Quick Disconnect (QD) mounting system points for attaching a strap, a boss for an accessory hand strap, and magnetic storage for the hex key. Additionally, the CNC machined 6061-T6 aluminum construction is finished with a Type II black anodizing and a laser-engraved center mark is placed on the rear of the plate for easy alignment.
