Thanks for the replies. I hesitated to buy the Polar Pro because it appears to only come in a 3-pack for the
P4P and only combined with ND (it seems you could buy only the polarizer for previous versions, but I don't see a polarizer only from Polar Pro for the
P4P.)
For DSLRs I've been accustomed to choosing a polarizer that has the least light loss to maintain fastest auto focusing, etc.; my Nikon CPs have a Filter Factor 2.3 - 2.8 (1.2 - 1.5 Stop).
It appears the Polar Pro set for the
P4P includes:
- ND4/PL Filter (2-Stop)
- ND8/PL Filter (3-Stop)
- ND16/PL Filter (4-Stop)
So the ND4/PL at 2 stops loss appears the closest to what I'm accustomed to on other cameras as a polarizer (different ballpark, granted.) Suspect I won't get much use out of the bundled ND8/PL or ND16/PL, but maybe they will be useful for me for video later if I get into more video...
