Depending on the lighting conditions: bright sun really needs an ND16, on overcast days or late afternoon an ND8 is enough. I use only these. You want the shutter speed to be about double the frame rate (25 fps => 1/50 sec exposure). When shooting photos instead of video don't forget to remove the filter. As for a polarized filter, you've got a fairly wide-angle lens; the polarization varies across that field, so personally not sure that its so useful in this case. |
