The Urth 37mm Magnetic Adapter Ring is a precision-engineered filter adapter designed for seamless integration with compatible camera lenses and filters. This adapter features a sturdy 37mm thread and a magnetic connection system for quick attachment and removal of magnetic filters without the need for threaded screws. Made from high-quality aluminum with an anodized finish, it offers reliable durability at a weight of approximately 15g. The adapter measures 37mm in diameter and 3mm in thickness, minimally affecting lens barrel compatibility. The magnetic system provides a secure hold with approximately 1.2kg of pull force, preventing accidental detachment while still allowing for effortless filter changes. It is compatible with all Urth magnetic filters and other magnetic filter systems of similar specifications. The precision-engineered threads allow for smooth screwing into lens filter threads, while the anti-reflective coating on both surfaces minimizes internal reflections and lens flares. This adapter enables photographers to maintain optimal image quality and streamline their filter workflow—especially useful for landscape, travel, and outdoor photography, where quick filter changes are often necessary. Its compact design is suitable for travel gear and field use, with dimensions that allow for storage in most camera bags. The adapter undergoes quality control tests for thread accuracy and magnetic alignment, ensuring consistent performance across all production batches. It represents a practical solution for photographers looking to enhance the efficiency of their filter system without compromising optical performance or equipment protection.
