Kolari Vision Kolari Pro 52mm IR ND 4-Stop Filter

We are proud to announce that we are entering the ND filter game. Anybody who uses our products knows that we put quality and customer support above all. So we used high quality materials, bleeding edge technologies and years of experience to make this the best filter there is.

Color Perfection
Optically engineered to be the most neutral filter in the visible light spectrum and beyond into the infrared range. This filter delivers the most neutral darkening in every wavelength, and at every angle. Ultra-wide angle tested and approved for excellent vignetting and color cast performance. Designed for whatever you can throw at it.

Ultra Strong Gorilla Glass
Built with premium ultra-thin, ultra-strong Corning Gorilla Glass, this filter is more than two times stronger than Schott B270 glass to direct impacts, and more resistant to scratches for better long term durability, all while also boasting a high internal transmission and lower refractive index than Schott B270 for sharper images.

Premium Coating
We topped off the perfect glass with premium coatings to make the already durable glass water, oil, and scratch resistant, while reducing reflectivity.

The Perfect Grip
We added a two stage knurling to the edges to make the ultimate high friction grip for easier handling with gloves or dry hands in any weather.

Ultra Thin Brass Ring
We housed our filter in a precision machined 3.4mm slim brass frame for reduced vignetting and a smoother installation than aluminum, reducing cross threading and jamming. High friction knurling provides an easier grip with gloves or dry hands in any weather. This filter just feels great.
