Customer Reviews (4.4 / 5 · 5 reviews)

Owen S. ★★★★★

For astrophotography, the precision of the 0.5mm increments makes fine-tuning back focus incredibly easy. The set covers the full 13.5mm adjustment range, and the through holes align perfectly with my gear.

Sophia ★★★★★

The five-step adjustment range is exactly what I needed for dialing in back focus—the 7mm shim alone solved my spacing issue. Machining is clean and the through holes lined up without any fuss.

William R. ★★★★★

The five adjustment shims let me dial in the back focus precisely for my camera and reducer setup, and the 13.5mm total range saved me from buying multiple spacers. The through holes made installation a breeze since I didn't have to disassemble the entire train.
