The Pro Brass 67-52mm Step-Down Ring from Sensei allows 52mm-diameter threaded filters to be mounted onto lenses with 67mm filter threads. This ring removes the need to stack multiple filters for each lens thread size increasing the capability across a range of available lenses. The stronger brass construction is less likely to bind or become jammed, and with the large edge knurling, it's easier to grip and remove from equipment.

Step-Down Capability
The Sensei PRO Step-Down Ring allows 52mm threaded filters to be used on lenses with on 67mm filter threading. This is a great way to get more functionality out of smaller filters and use them on larger lenses.

Brass Construction
Brass is resistant to warping and is less prone to jamming or binding, and knurled sides making it easier to grip and remove from lenses, filters, and additional step-down rings. The matte-black anodized finish resists corrosion and reduces reflections to maintains image quality.
