I see there are ND filters like ND4, ND8, etc... and I see there is variable ND filter which can be adjusted.
My concern is....how separate ND filters can be compared to this one variable ND filters. Is it for sure the same effect, or it is better to use separate ND filter for every situation you need ?
One more thing...how about ND/CPL filter in one. Is this good thing ?
