NiSi Square Filter M75 II Professional Kit

NiSi Square Filter M75 II Professional Kit – 75mm holder with True Color CPL and a set of ND/GND and specialty filters

This NiSi M75 II Professional Kit gives filmmakers and photographers a complete 75mm square filter solution. It includes a rotating holder with an integrated ultra-slim True Color circular polarizer (CPL) and a selection of neutral density, graduated and specialty filters. The kit suits mirrorless camera systems and accepts 75mm wide square filters (2 mm thick) from NiSi and other brands.

Designed for mirrorless cameras

The kit was made especially for mirrorless cameras. It supports 75mm wide square filters that are 2 mm thick, whether they come from NiSi or other manufacturers. Consequently, you can combine NiSi filters with compatible third‑party 75mm filters you already own.

Holder design and operation

The NiSi M75 II holder rotates a full 360 degrees and locks in any desired position, so you can precisely position graduated filters or the polarizer. The holder is constructed from aviation-grade aluminium and features a new locking design for the filters. This updated locking mechanism makes inserting and removing filters very smooth.

Polarizer operation without removing square filters

The kit includes an ultra-slim circular NiSi True Color Polarizing filter (CPL). Thanks to a unique design, you rotate the polarizer via a small wheel on the back of the holder. In practice, this means you do not need to detach any square filters to adjust the polarizer, which speeds up workflow on set.

Adapter compatibility and options

The holder ships with a standard 67mm main adapter ring. In addition, the holder can accept adapter rings for camera lenses with filter threads between 40.5 mm and 62 mm. Adapter rings are sold separately; the kit lists the available additional adapter sizes for quick reference.

• Standard main adapter: 67 mm
• Available additional adapter rings (sold separately): 40.5 mm, 43 mm, 46 mm, 49 mm, 52 mm, 55 mm, 58 mm and 62 mm
