Kase K100 StepDown Ring 77-95

The K100 StepDown Ring 77-95 is a precision filter adapter designed to connect larger diameter lenses to smaller filter threads, specifically converting from 95 mm to 77 mm thread sizes. This adapter ring enables photographers to use 77 mm filters on lenses with 95 mm filter threads, providing compatibility across different lens systems while maintaining optical quality.

Constructed from durable aluminum alloy with a matte black finish, the ring features precise machining for secure attachment without light leaks or vignetting. The adapter maintains a low profile design with a thickness of approximately 3 mm to minimize interference with lens hoods and other accessories. Threads are precision-cut for smooth engagement and secure locking, with brass construction in the threaded areas for enhanced durability and resistance to cross-threading.

The ring includes a rubberized grip surface for easy handling during filter changes, even in challenging conditions. This adapter is compatible with various filter types including circular polarizers, neutral density filters, and UV filters from major manufacturers. The K100 StepDown Ring is designed for professional and enthusiast photographers who require reliable filter compatibility across multiple lens systems without compromising image quality.

The adapter features anti-reflective coating on interior surfaces to minimize flare and ghosting, and includes a protective storage pouch for transportation. Weight is approximately 45 g, making it lightweight for inclusion in camera bags without adding significant bulk. This filter adapter represents a practical solution for photographers seeking to standardize their filter collection across lenses with different thread sizes while maintaining optical performance and build quality.
