Decided to try this out after seeing someone do it. The result???
1) Video overall looked better and softer compared to original
2) Lesser “white washing” when look straight at sun
3) Contrast on the ground is better with better clarity
1) Some lens flare
2) Can see some of the edges of the filter which i think can easily be improved
The test setting: Sunny morning and clear skies!
Filter used : ND16
Verdict? I love it! Its gonna be a must have add on for my Caddx on a bright sunny day!
