Ulanzi CA03 95mm Rotatable Collar Adapter Ring

The Ulanzi CA03 95mm Rotatable Collar Adapter Ring is a durable and lightweight lens collar tripod mount designed to improve balance, stability, and protection when working with heavy lenses. Featuring smooth 360° rotation, Arca-Swiss compatibility, and an adjustable platform height, it’s an ideal solution for professional photo and video setups.

The Ulanzi CA03 is a precision lens collar tripod mount engineered for lenses with a 95 mm diameter, offering enhanced stability and improved load distribution for heavier camera setups. By transferring the weight from the camera bayonet to the tripod, the CA03 helps protect your camera mount while delivering better balance and steadier framing in both studio and outdoor shooting environments.

Its integrated rotary mechanism allows fast and effortless switching between landscape and portrait orientation without removing the camera from the tripod. A large, ergonomic locking knob enables smooth, precise rotation in one motion, saving valuable time during dynamic shoots.

The built-in Arca-Swiss–compatible mounting plate ensures quick attachment to most tripod heads, sliders, and gimbals. For expanded compatibility, the base also includes standard 1/4"-20 and 3/8"-16 tripod threads, making it suitable for a wide range of professional support systems.

An adjustable platform height allows fine-tuning for different lens designs, while the semi-circular collar design enables installation without removing the lens from the camera. Constructed from scratch- and corrosion-resistant aluminum and steel, the CA03 supports lenses weighing up to 5 kg, all while maintaining a lightweight and portable form factor.
