NISI IR / UV CUT Slimline 39mm filter.

NiSi IR/UV Cut Filters.

These are from a special production run made by Nisi for Mainline Photographics.

They are only available in 39mm and 46mm. They are in a slim mount with front threads.

This filter is essential if you are using a Leica M8 or M8.2.

The NiSi IR/UV Cut Filter is designed to deliver the clearest, most colour-accurate images possible by blocking both ultraviolet (UV) and infrared (IR) light before it reaches your camera sensor. While modern digital sensors are highly sensitive to UV and IR light, these wavelengths can cause unwanted haze, colour shifts, and reduced contrast—especially when shooting with today’s high-resolution lenses.

Crafted from optical-grade glass with multi-layer nano coatings, the NiSi IR/UV Cut Filter ensures exceptional light transmission across the visible spectrum while effectively cutting UV and IR contamination. The result is sharper detail, improved colour fidelity, and cleaner files straight out of the camera.

Eliminates UV and IR pollution for natural, accurate colours.

High-quality optical glass with precision nano coatings.

Ultra-thin frame design to minimise vignetting on wide-angle lenses.

Protective filter doubles as a front element safeguard against dust, scratches, and fingerprints.

Ideal for photographers who demand maximum image clarity—whether you’re shooting landscapes, portraits, or technical photography where colour accuracy is critical.
