Universal 77mm to 72mm Step Down Ring

This step down ring adapts a lens with a 77mm filter thread to accept 72mm filters. It is designed for photographers who own larger-thread lenses but want to use smaller-diameter polarisers or other accessories without buying duplicates.

Polariser filter type

The ring is specified as a polariser type, meaning it is intended to hold a circular polarising filter in the smaller 72mm size. Buyers who need a plain mechanical adapter for neutral density or colour filters should verify compatibility before ordering.

Simple screw-on installation

The ring threads directly onto the 77mm front of the lens and the 72mm filter screws into the ring. Over-tightening can bind the threads, so tighten only until snug. Vignetting may occur on wide-angle lenses because the adapter adds thickness to the filter stack.

Questions about this item

How does the 77mm to 72mm step-down change what filters I can use on my lens?

It lets you mount 72mm threaded filters onto a lens with a 77mm front thread, so you can reuse smaller polarizers or other filters without buying new 77mm versions.

Does the polarizer type affect how much light the ring blocks or the rotation feel?

The ring itself is a passive adapter; the polarizing effect and rotation stiffness come entirely from the 72mm filter you screw into it.

Will the 77mm male thread on this ring fit my lens without vignetting on a full-frame wide-angle?

The ring adds about 5 mm of thickness, so on ultra-wide lenses you may see corner darkening; test at your widest focal length before critical shoots.
