The RRS® Sony Alpha A1ii/A9iii Series Modular Plate System

Trusted by professionals and dedicated enthusiasts worldwide, RRS delivers the precision and durability serious creators demand. When your Sony a1 II or a9 III is paired with long lenses, gimbals, or support systems, you need a mounting solution that stays stable, predictable, and rock-solid—no matter where your work takes you. For exact dimensions, weight, and compatibility details, view the full specification table below.

Precision Where It Matters. Stability for the Core Camera Setup

Designed specifically for the Sony a1 II and a9 III body, the BGC5 base plate delivers a perfectly fitted, anti-twist foundation for demanding shooting conditions. Precision-machined contact surfaces prevent rotation and maintain exact camera alignment, ensuring consistent framing and smooth movement on tripods, gimbals, and heads. Laser-engraved center marks and a captive mounting screw make setup fast and repeatable, while compatibility with RRS QD and hand-strap accessories adds secure, photographer-focused versatility.

One System. Endless Configurations

The BGC5 is the heart of the Sony Alpha Modular Plate System—serving as a low-profile, lightweight foundation that can remain on your camera full-time. It provides full access to the battery door and all camera ports, so nothing interrupts your workflow. Integrated hex-key storage makes adjustments quick in the field, and compatibility with optional vertical brackets and video accessories allows the platform to evolve seamlessly as your needs grow.

Heirloom Build Quality, Engineered for Longevity

Machined from solid 6061-T6 aerospace-grade aluminum, this L-Bracket is built to withstand the realities of professional use. Advanced CNC machining ensures tight tolerances and exceptional structural integrity, while a Type II hard-anodized finish provides long-term resistance to wear, corrosion, and the elements. Critical fastening points utilize 303 stainless steel hardware, chosen for its strength, corrosion resistance, and reliability under repeated load. The result is a precision tool designed to perform flawlessly in rain, dust, cold, and heat—engineered not just to last, but to be trusted for years of hard use.

Seamless Arca Compatibility, Engineered to RRS Standards

The BGC5 features a precision-machined Arca-style dovetail that conforms to the 1.5" RRS Dovetail Standard for secure, zero-play engagement with RRS and most Arca-type clamps. Integrated RRS-Lock® safety stops add an extra layer of protection against accidental release—keeping your Sony body safe whether mounted on a tripod, ball head, or support system.
