NiSi M75 Starter Kit 75mm System

NiSi M75 Starter Kit 75mm System – Rotating 360° holder with integrated ultra-slim CPL

The NiSi M75 Starter Kit 75mm System is designed for mirrorless cameras and compact cameras. It supports 75mm wide square filters (2 mm thick) from NiSi and other brands. The kit combines a compact, robust filter holder with a selection of graduated and neutral density filters plus practical accessories for everyday use.

Key features and construction

The filter holder rotates a full 360 degrees and locks in any desired position. You get precise control when composing and balancing light. Additionally, the holder uses a new locking design that secures filters while making insertion and removal smooth.

NiSi manufactures the holder from aviation-grade aluminium. This material gives the holder a durable feel while remaining suitable for on-location work with mirrorless and compact systems.

Integrated polarizer and operation

The kit includes an ultra-slim circular NiSi Polarizing (CPL) filter. Instead of removing square filters to adjust polarization, you rotate the polarizer using a small wheel on the back of the holder. This setup saves time and keeps your filter stack intact while you fine-tune reflections and contrast.

Mounting and adapter options

The standard mount fits a 67 mm filter thread. However, the holder also accepts adapter rings for smaller threads, so you can use the M75 system on many lenses. Adapter rings are sold separately; see the full list below.

Lens compatibility and vignetting

The NiSi Filter Holder M75 suits APS-C lenses with focal lengths as short as 11 mm (ultra-wide-angle) without producing vignetting. You can also use it on some 10 mm APS-C lenses, but slight vignetting may occur if the holder is rotated to a 45° angle.

For Micro Four Thirds cameras, the holder works on lenses down to 8 mm without risk of vignetting.

FAQ

Question: Which cameras and lenses is the M75 Starter Kit designed for?

Answer: The kit is made for mirrorless cameras and compacts. It supports 75 mm wide square filters and fits APS-C and Micro Four Thirds systems within the compatibility ranges described. For APS-C, the holder works down to 11 mm without vignetting; for Micro Four Thirds, down to 8 mm.

Question: Do I need to remove square filters to adjust the polarizer?

Answer: No. The included ultra-slim circular CPL is adjustable via a small wheel on the back of the holder, so you can rotate the polarizer while leaving square filters in place.

Question: What if my lens has a different filter thread than 67 mm?

Answer: The standard mount fits 67 mm threads, but you can use adapter rings (sold separately) for threads from 40.5 mm up to 62 mm. See the adapter ring list above for available sizes.

Question: Will the holder cause vignetting on ultra-wide lenses?

Answer: On APS-C lenses, the holder avoids vignetting down to 11 mm. It can be used on some 10 mm lenses, although slight vignetting may occur when the holder is rotated to a 45° angle. On Micro Four Thirds, it is suitable down to 8 mm without vignetting.
