48mm Canon DSLR 廣角T接環 (SFFTCANON)

The bigger 48mm thread made all the difference for my astro setup—edge stars stay round with the flattener attached. It threads on smoothly and locks tight without any play. Exactly what I needed to kill the vignetting on my Canon.

This 48mm ring fits my Canon perfectly and the wider thread on my flattener made assembly super easy. I’ve noticed way less vignetting in my shots compared to the standard size ring I was using before.

Threaded onto my flattener without any binding, and the larger 48mm opening completely eliminated the corner darkening I used to see with standard t-rings. It's a solid, precision-machined piece for anyone doing wide-field astrophotography with a Canon DSLR.
