Customer Reviews (4.6 / 5 · 5 reviews)

George D. ★★★★★

The 4mm thickness is perfect for my imaging train, keeps everything tight without adding bulk. No light leaks at all thanks to the adapter, which fixed the gradient issues I kept getting on long exposures. Threads are smooth and it screwed right onto my camera without any play.

Emily ★★★★★

The six through holes made mounting my filter wheel way easier than the single-threaded adapter I had before. Threads are machined cleanly and the lightproof piece actually seals — no more faint glow creeping into long exposures.

Emma R. ★★★★★

Even with a small spacing budget, the 4mm thickness kept everything rigid, and the lightproof adapter completely eliminated any stray glow from my setup.
