Customer Reviews (4.8 / 5 · 5 reviews)

Madison P. ★★★★★

The CNC machining is spot on—threaded on perfectly with zero wobble. Adding that 1mm gap between my flattener and camera made all the difference in my corner stars.

Joseph D. ★★★★★

Was having trouble with star shapes in the corners until this 1mm spacer got the back focus just right. The CNC machining is clean and threads on smoothly without any binding. Exactly what I needed for fine-tuning my imaging train.

Amelia Z. ★★★★★

Took a chance on this to fine-tune my backfocus, and the machining is spot-on—edges are clean, and it sits perfectly flush against the flattener and camera. That extra millimeter made a subtle but real difference in the corner stars.
