T2-M48 Thread Adapter

Description

A T2 to M48 step-up thread adapter with M48×0.75mm male threads on one side and T2 (M42×0.75mm) female threads on the other. The adapter has zero optical length (0mm), meaning it adds no distance to your imaging train’s back-focus calculation.

Use this adapter to connect T2-threaded cameras or accessories to M48-threaded components such as field flatteners, focal reducers, or telescope back-focus ports. The zero-length design is particularly valuable when you’re tight on back-focus distance and can’t afford any extra spacing in the optical train.
