The Kase Magnetic Adapter Step Ring Circ 67-112 mm is a precision-engineered filter adapter for camera lenses. This adapter ring allows for seamless magnetic attachment of compatible filters to lenses with filter thread sizes ranging from 67 mm to 112 mm. Made from durable aluminum alloy with a black anodized finish, the adapter provides reliable mounting at a minimal weight of approximately 45 g. The magnetic connection system ensures quick filter changes without threaded screws and reduces the risk of cross-thread damage to lens threads. The adapter features a slim profile of 5 mm thickness to prevent vignetting with wide-angle lenses. Compatible with Kase magnetic filter systems and other magnetic accessories, this adapter maintains optical alignment and does not add additional glass elements that could compromise image quality. The standard black surface minimizes reflections and blends unobtrusively with most camera gear. The adapter is precision-machined with exact tolerances for a secure fit and correct alignment with lens filter threads. This accessory is particularly useful for photographers who frequently switch between different filter types or need quick filter changes in dynamic shooting situations. The magnetic system allows for one-handed operation and is practical for landscape, travel, and outdoor photography, where efficiency is crucial. The adapter is designed for regular use and retains its magnetic properties and structural integrity over time. Each adapter undergoes quality control for consistent performance and compatibility with specified lens sizes.
