48mm T-Ring for Sony E-mount - Black

The William Optics 48mm T-Ring for Sony E-mount is a precision-engineered adapter that converts Sony E-mount cameras to a standard 48mm T-thread, enabling compatibility with M48-threaded telescope optics and astronomy accessories. CNC-machined from high-quality aluminum with black hard anodizing, this adapter provides a secure, wobble-free connection between your Sony mirrorless camera and telescope equipment. With an optical path length of 36.7mm, it perfectly aligns with the Sony E-mount's 18mm flange focal distance to achieve the standard 55mm back focus requirement for correctors and flatteners, eliminating the need for additional spacers.
