Or both?? lol. This mavic has really bad lens flare or glare. What have you all tried with success? I was thinking of a polarizer or ND filter. Rather just get the CP filter to block out any light if possible. I know PP has a ND4 and Polarizer in one but the 2 stops of light is a big hit at dusk......Or maybe a lenshood? Whats your experience?? TIA, Dave
