NiSi 75mm System M75 Adapter Ring 72mm

These rings allow you to adapt the 67mm main ring included in the NiSi M75 Holder with lenses having a frontal thread from 39 to 67mm. The adapters can also be used as 67mm step-up rings, for example to use 67mm circular filters on other lenses. Choose the size, from 39mm up to 67mm*.

There is no need to over-tighten the ring. As soon as you feel resistance the ring is secured.
