NiSi 111088 52mm Adapter for M75 System

The NiSi 111088 52mm Adapter is a step-up ring that connects lenses with 52mm filter threads to the NiSi M75 75mm filter system. It threads onto your lens and adapts it to the 67mm main adapter ring on the M75 holder, giving photographers with smaller-threaded lenses full access to NiSi's compact 75mm graduated ND, polarizer, and specialty filters. This is especially useful for landscape and long-exposure photographers who use a variety of lens sizes but want to standardize on a single filter system.

Constructed from aluminum alloy, the adapter is built to withstand the demands of outdoor shooting while remaining light enough to carry without adding meaningful weight to a filter kit. The machining is precise, ensuring the ring threads on smoothly and holds securely without cross-threading or play. As a system component, it works exclusively with the NiSi M75 ecosystem — it is not a generic step-up ring — so buyers should confirm they already own or plan to purchase the M75 holder and main adapter ring to complete the setup.
