Customer Reviews (4.4 / 5 · 5 reviews)

Joshua N. ★★★★★

Finally, an adapter that lets me use my Canon glass with my 2-inch filter wheel without any wobble. The M54 threading is precise and locks on perfectly. My first test image showed noticeably sharper stars compared to my old setup.

Riley ★★★★★

Snug fit on my 2" filter wheel with zero wobble, and the M54x0.75 thread cut is clean enough that it spins on smoothly. I was worried about tilt with the added lens weight but stars stay round right to the corners.

Edward ★★★★☆

The M54 thread fits my 2-inch filter wheel perfectly, and the build feels solid enough for long exposures. Only wish the instructions were clearer about the exact backfocus distance.
