A Step-Down Adapter Ring enables you to use smaller size filters on lenses with a larger diameter thread. This allows you to maximize the use of your existing filters and lenses.
The '77mm to 67mm' specification indicates the lens and filter sizes the adapter ring is compatible with. The first number (77mm) is the size that screws into the lens, and the second number (67mm) is the filter size it can accommodate.
Vignetting is a reduction of an image's brightness or saturation at the periphery compared to the image center. It can occur when using step-down rings. However, this can often be mitigated by adjusting your camera settings or cropping the image in post-production.
Yes, the Step-Down Adapter Ring is designed for easy installation. Simply screw it into your lens, then attach your filter to the adapter ring.
Yes, this adapter ring is designed to be universally compatible with any 77mm lens and 67mm filter, allowing for versatile use across your photography equipment.
Review Summary

I simply ordered a step down ring when I should've ordered a step up ring. I want to adapt a larger ND filter to a smaller lens. I have since reordered the correct adapter & everything on that review will be 5-stars. Since my mistake is so inexpensive I'm not bothering with a return. (BTW who'd want to attach a smaller filter to a larger lens, anyway???) Adorama makes it very easy to order.

sorry but, I had to give this a 2 rating because, the 67mm side did not fit. It was too big, and I had to order another one. I did not send it back because the 77mm side fit, and I just may be able to use it in the future on another lens.
