Breakthrough Dark 6-Stop Circular Polarizer Magnetic Filter

Breakthrough Dark 6-stop Circular Polarizer Magnetic Filter

The Breakthrough Dark 6-Stop Circular Polarizer Magnetic Filter features a developed CPL film, state-of-the-art coatings and a precision-machined brass traction frame making it a sharp and colour neutral polarizer. This filter is a real must-have for outdoor photographers.

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 passes or blocks a filter. The data is displayed as line graphs with light transmission percentages for each measured wavelength.

A perfectly flat light transmission curve would produce a perfectly colour neutral result. Although this is technically impossible, the X4 CPL is guaranteed to have the flattest transmission curve of any polarizer on the market. This translates into a more colour neutral performance with no colour cast.
