NiSi Filter Holder Kit M75-II True Color – 360° Rotatable Holder with Ultra Slim CPL

This NiSi Filter Holder Kit M75-II is a metal filter holder designed for mirrorless cameras. It accommodates up to two 75 mm square filters and includes a NiSi True Color polarizing filter (CPL). The kit also includes a semi-soft storage case for the holder and filters.

Key features

• Fits two 75 mm square filters (75x80 mm or 75x100 mm, 2 mm thick) from NiSi and other brands.
• 360° rotation with locking — rotate the holder fully and lock it in any desired position.
• Aviation-grade aluminium construction with a new locking design for smooth insertion and removal of filters.
• Integrated ultra slim True Color CPL that installs and removes quickly and conveniently.
• Polarizer adjustment via rear wheel — rotate the CPL using a small wheel on the back of the holder without detaching square filters.
• Standard 67 mm main adaptor with support for additional adaptor rings to fit other filter threads.
• Includes semi-soft pouch for safe storage and transport of the holder and filters.

Compatibility and lens use

The NiSi M75-II is made especially for mirrorless camera systems. It fits NiSi square filters sized 75x80 mm or 75x100 mm with a thickness of 2 mm, and it will accept compatible filters from other brands that meet those dimensions.

On APS-C cameras, use the holder with lenses as wide as 11 mm without vignetting. You can also use it on 10 mm APS-C lenses, although slight vignetting may occur when the holder is rotated to a 45° angle.

For Micro Four Thirds cameras, the holder supports lenses down to 8 mm focal length without risk of vignetting. These compatibility notes help you choose lenses and filter setups for wide-angle work.

Adapter rings

The standard mount supplied with the holder is a 67 mm main adaptor ring. You can expand compatibility using additional adaptor rings (sold separately) for the following thread sizes:

• 39 mm
• 40.5 mm
• 43 mm
• 46 mm
• 49 mm
• 52 mm
• 55 mm
• 58 mm
• 62 mm

What the kit includes

FAQ

Question: Will the holder cause vignetting on my wide-angle lens?
Answer: It depends on your camera format and focal length. On APS-C, the holder works down to 11 mm without vignetting and can be used at 10 mm with possible slight vignetting at certain rotations. On Micro Four Thirds, it supports lenses down to 8 mm without vignetting.

Question: Can I adjust the polarizer without removing square filters?
Answer: Yes. The CPL rotates via a small wheel on the back of the holder, so you can fine-tune polarization without detaching any square filters.

Question: Are adapter rings included for all filter threads?
Answer: The kit includes a standard 67 mm main adaptor ring. Additional adaptor rings for 39–62 mm thread sizes are available separately and can expand compatibility to smaller lenses.

Question: How easy is it to insert and remove filters?
Answer: The holder uses a new locking design and is made from aviation-grade aluminium, which makes inserting and removing filters smooth and straightforward while keeping them secure when locked.

Question: What is included in the kit and how is it stored?
Answer: The kit includes the NiSi M75-II filter holder, the NiSi True Color CPL, the standard 67 mm adaptor ring, and a semi-soft NiSi M75 pouch for the holder and filters, providing convenient storage and transport.
