NiSi 39mm Armor FX PRO Nano L395 UV-beschermingsfilter

Swapped this onto my wide-angle lens for a mountain landscape shoot, and the glass is so clear I forgot it was even there—zero color cast. The nano coating repelled water droplets beautifully when a sudden drizzle hit.

The knurled ring is grippy enough that I don't fumble when swapping it out on a cold morning, and it sits flush on the lens with zero vignetting. Mounted it on my 40mm and forgot it was there — shots stay crystal clear even with the sun low in the frame.

The coating on this thing is a beast — it shed a splash of saltwater at the coast without a single smear, and the glass stayed crystal clear. Mounted it on my 39mm lens and forgot it was there, which is exactly what I want from a UV filter.
