ND filter test
Comparison of ND 10-stop filters showing color and transmission quality.
Test performed by Progrey-Filters Corporation in 2014. Comparision of glass ND filters. Genesis achieves extremely minimal color shift with a pleasant natural color and adds no extra vignetting aside from the lens vignetting. High density ND filters normally add strong dark corners around the image (vignetting), but not Genesis and Aurora Extreme series filters. Genesis ND filters are made with a very strong anti-reflection and anti-static (anti-dust) coating.
None of the Genesis square filters create objectionable light leaks when used with Progrey holder systems.
