Check vignettingThe Starizona M48 to M54 Step Ring is a simple, robust adapter designed to connect two common but incompatible thread sizes in an imaging train. It features internal M48 female threads to accept filters or correctors and external M54 male threads to mount to focusers or other accessories, creating a secure, non-flexing connection.
This adapter solves a common problem: connecting an accessory with M48 threads, such as a 2" filter or a field flattener, to a component that uses the larger M54 standard. The ring steps the thread size up from 48mm to 54mm. This version includes a physical lip, which acts as a hard stop when threading the adapter into a female port, ensuring it seats fully and squarely without being threaded too deeply.
The adapter has M48 female threads on the inside and M54 male threads on the outside. This allows you to connect a component with male M48 threads to another component with female M54 threads.
The lip serves as a mechanical stop. When you thread the adapter into a component, the lip ensures that it stops at a fixed position, preventing it from being screwed in too far. This provides a consistent and secure connection.
It acts as a "step-up" ring. You would typically thread your M48 accessory (like a filter cell or reducer with male threads) into the female side of this adapter. The entire assembly then presents a male M54 thread that can be connected to your focuser, camera rotator, or other M54-threaded accessory.
