Customer Reviews (4.8 / 5 · 5 reviews)

Aurora E. ★★★★★

This adapter fit my setup perfectly—the clear aperture of 65mm lets plenty of light through for my camera sensor. The threading was smooth and precise, no wobble at all when attached.

Thomas F. ★★★★★

The 3.5x24tpi to M72x1mm threading aligned perfectly with my Tak mount—no wobble at all. The 65mm clear aperture is generous enough for my setup without vignetting.

Ryan E. ★★★★★

Finally an adapter that fits precisely—the clear aperture of 65mm lets my full frame sensor see the whole field without vignetting. The threading matched up perfectly on the first try, which saved me a lot of frustration.
