We stand behind every filter we make with our 25 Year Ironclad Guarantee. Our team spent years developing each aspect of the filter to maintain optical performance and reliable function for a lifetime of use. So we guarantee that our filters will remain free from manufacturers defects for 25 years from the date of purchase.

Increased average transmission also leads to better performance. Higher light transmission allows more light to pass through to the sensor, which translates into faster shutter speeds, sharper images and the ability to use a lower ISO when shooting video. The X4 CPL features the highest average light transmission - 47.18% - of any available CPL without sacrificing polarization efficiency.

Spectrometers are optical instruments used to measure the properties of light across a spectrum. Wavelength and intensity are detected to determine the percentage of light that a filter transmits or blocks. The data are displayed as line graphs with light transmission % values for each wavelength measured.
