The Circular Glass Adapter (CGA-138) is an add-on accessory within the Bun-G-Ring ecosystem, designed for mounting 138 mm circular glass such as diopters, polas, and similar round optical elements via an existing Bun-G-Ring. Description: The CGA connects to the Bun-G-Ring (not included) using the bungee cords and features a Spring & Lock Mechanism that allows circular glass to be loaded and swapped from the front, while ensuring a secure hold. Multiple CGAs can be stacked, for instance when using diopters to achieve higher magnification. Rectangular filters can also be used at the same time, positioned either in front of the CGA or between the CGA and the Bun-G-Ring depending on the desired optical effect, while an integrated silicone Grip Seal protects the rectangular glass. Compatible glass diameter: 138 mm circular glass The CGA-138 comes with a neoprene sleeve that fits inside the Standard Kit pouch, and a Quick Start Guide. ♻ The shipping box and all packaging materials are made from recyclable and biodegradable materials.
