حلقة تخفيض 2"i / T-2a بطول بصري 1.5 مم (BPR2T2-15)

This tiny adapter solved my spacing issue between the camera and corrector perfectly. The 1.5mm optical length is barely there, which is exactly what I needed to reach focus.

The 1.5mm optical length is exactly what I needed to squeeze my camera sensor into the right spacing, and the low-profile design keeps everything rock solid with zero play. It threads on smoothly and feels machined well, so my setup finally looks clean instead of a stack of spacers.

Finally got the backfocus down to exactly 1.5mm with this ring, which cleared up the star elongation I'd been fighting for weeks. The low-profile design threads on smoothly and it feels solid once torqued down. Really glad I swapped out the bulky adapter for this one.
