Stepping rings

A stepping ring enables a lens to be fitted to a camera with a different thread size (or a filter to a different size lens).

Not all filters come in all thread sizes, but you can still use the filter you want, even if not listed as available to fit your camcorder. Simply order the nearest larger size filter together with the appropriate stepping ring.

Just in case you're wondering whether you need a step-up or a step-down ring, the first ring measurement in the lists is the CAMERA thread diameter, the second is the LENS thread diameter (or first, lens, second filter)
