Going ahead with reviews we have finally received ND filter. It’s not tested yet but I would try to show you my very first lookup. ND filter As discussed in the previous post, it is an alternative complement to sports cameras, different from the UV filter. Remembering UV one, it doesn't affect the images or logs at all, but I have noticed it's very useful in protection performance. ND filter, instead , set some slight changes to video records. Protection performance is the same as UV, but introducing some improvements, such as jelly effect narrowing, for example. As is known, jelly effect is the feeling of keeping the trembling in the video recordings. First lookup Contrast inbetween is very evident in first view after checking these filters (ND and UV), due ND filter present a smoked plastic cover while UV it’s totally transparent. ND filter (left) vs UV filter (right) Manufacturing instead it’s almost the same. Both filters are almost twins...
