This adapter provides 5mm of fine adjustment, from a minimum length of 15mm to a maximum of 20mm. This range is ideal for closing small, specific gaps in an M48-threaded imaging train, ensuring your sensor is positioned at the precise focal plane dictated by your flattener or reducer. For larger spacing requirements, Starizona also offers 20-30mm and 30-40mm versions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the adjustment range of the Starizona Variable M48 Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis version of the Starizona Variable M48 Adapter is continuously adjustable from a minimum length of \u003cstrong\u003e15mm\u003c\/strong\u003e to a maximum of \u003cstrong\u003e20mm\u003c\/strong\u003e, providing a total adjustment travel of 5mm.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat thread type does the Starizona Variable Adapter use?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe adapter uses standard \u003cstrong\u003eM48 threads\u003c\/strong\u003e (male on one side, female on the other).
