The Urth 77-82mm magnetic step-up ring lens filter adapter allows photographers to use 82mm filters on lenses with 77mm filter threads. This adapter system utilizes a magnetic connection technique for quick filter changes without threaded screws, reducing the risk of cross-thread damage to lens threads. Made from durable anodized aluminum, the adapter ensures precise tolerances for correct alignment and prevents light leaks. The step-up design increases the filter thread diameter from 77mm to 82mm, providing compatibility with larger filter systems while maintaining a slim profile to minimize vignetting. The magnetic interface supports Urth magnetic filter systems and other compatible magnetic accessories. With dimensions of approximately 82mm in diameter and 5mm in thickness, this adapter weighs about 45g. The black anodized finish reduces reflections and complements the aesthetics of professional photography equipment. This adapter is suitable for landscape, portrait, and studio photography applications where filter compatibility and quick changes are required. The precise machining ensures a secure fit without compromising optical quality or introducing distortions. As a successor to previous threaded adapter designs, this magnetic system represents an advancement in filter attachment technology for professional and aspiring photographers.
