The William Optics 48mm T-Ring for Nikon F is a precision camera adapter designed to connect Nikon F-mount SLR/DSLR cameras to M48-threaded telescope accessories and correctors. Manufactured from high-quality aluminum using CNC machining and finished with black anodizing, this adapter combines durability with optical precision. The optical path length of 8.5mm pairs perfectly with Nikon's 46.5mm flange focal distance to achieve a total back focus of 55mm, eliminating the need for additional spacers when used with M48-threaded telescope optics like correctors and flatteners.
