This is precisely the scenario the Wide T-Ring is designed for. A standard T-ring would act as a bottleneck for the light cone from a fast refractor, clipping the light before it reaches the corners of your Canon R5's full-frame sensor. By using the native S52 connection (and appropriate adapters to connect to your flattener), you maintain a wider light path, which significantly reduces vignetting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI have a 2\" nosepiece with T-2 threads.
