Emma ★★★★★ Oct 21, 2026

Needed the 3.3" to dial in back focus on my CDK20, and it threaded on smoothly with no slop. The anodized finish matches my other gear perfectly.

Julian B. ★★★★★ Oct 19, 2026

I was worried about getting the right spacing for my setup, but the 3.3" version fit the CDK20's 5.8" back focus perfectly. The threads are smooth and it holds the camera securely without any play.

The 2.8" spacer was exactly what I needed to hit the correct back focus on my setup. Threads are smooth and it holds my camera square to the optical path without any slop.
