48mm Nikon DSLR 廣角T環 (SFFTNIKON)

The 48mm thread on this t-ring mates perfectly with my field flattener, eliminating any wobble I had with smaller adapters. Build quality feels solid, and it locks onto the camera body with a satisfying click. Just what I needed for clean, round stars across the frame.

My SVX 70T field flattener threads perfectly onto this ring, and the oversized 48mm aperture means zero vignetting on my Nikon. The anodized finish feels solid and precise during setup.

Had no trouble threading onto my field flattener—the 48mm diameter is exactly what was needed for a secure fit. It locks down tight without any wobble, which makes a big difference in keeping stars sharp across the frame.
