NiSi UV filters
UV filters protect the lens from knocks and the elements and stop UV light reaching the sensor: below 395nm it can cause a slight blue cast in daytime shots in strong light.
NiSi makes several lines of UV filters, from 37mm up to 105mm, in top-quality optical glass: they differ in construction, coatings and visible light transmission.
What’s your lens diameter?
You’ll find it on the lens barrel or behind the cap, next to the ⌀ symbol. Or search for your lens or camera.

What to look for when choosing a UV filter
The glass
The glass in front of your lens has to be up to the job: all NiSi UV filters protect without affecting optical quality.
Strength
A UV is a sacrificial filter: it breaks instead of the lens. For the most extreme use, the Armor FX PRO protects without breaking, even against hard impacts.
Construction
Aluminium (UHC, Armor FX PRO, Air Protector) or brass (HT HUC MC, Air ULRC): they differ in lightness, smooth threading, strength and durability.
Coatings
All have anti-reflective coating against flare and ghosting. The HT HUC MC is also water- and oil-repellent; the Air ULRC has 48 layers, 99.9% lower reflectivity and handles sensors above 100 megapixels.

Screwing several circular filters on top of each other isn’t recommended: compatibility between stacked filters isn’t 100% guaranteed. If you use an ND, a polariser or a Black Mist, take off the UV: you avoid vignetting with wide-angle lenses, and the other filter protects the lens. To stack several filters choose the magnetic JetMag Pro: they attach to each other in a second and lock.
