M75 adapter ring (40.5mm)

The NiSi 40.5mm adapter for the NiSi M75 75mm filter system allows the use of the NiSi M75 filter holder on lenses with a 40.5mm filter thread. The adapter is simply attached to the 67mm adapter ring included in the M75 filter holder kit to ensure seamless integration.

Made from a durable aluminum alloy, the adapter offers high stability with low weight. It is the ideal addition to use the NiSi M75 system with lenses with a smaller front diameter, creating maximum flexibility when photographing.

Note: Our adapter rings provide a reliable and secure connection between your filter holder/filter and your lens. Please tighten the adapter rings only so that your fingers can easily slip through – this ensures optimal hold while preserving the material. Tighter fastening is not necessary.
