Looking at the PolarPro and Freewell ND filter offerings for the A3s, (price and overall quality aside), noticed their offerings are for split ND filters both have a different strategy in the amount of split for the 2 cameras.
With the 2 cameras having 2 different apertures, (1.8 and 2.8), I like the idea of the split ND filter to help balance out the exposure when switching back and forth during a shoot. In my limited understanding of the numbers, maths, etc, at these apertures there are no exact ND exchanges for exact same exposure for both cameras, and these splits are what are available...
Freewells splits are; ND8/16, ND16/32, ND32/64, ND64/128.
PolarPro splits are; ND4/8, ND8/32, ND32/128.
Am I right in seeing the PolarPro strategy might be a little closer to optimum on the conservative side vs Freewell? Or am I trying to split hairs too close on a camera system that's not that optimized to get that far into the weeds begin with?
