CPL not just for landscape, can use for product shots also.

I too have a CPL, but it is almost never left on my lens. Usually put on when I need it, and it is always a UV on it all the time.

CPL could help bring out detail in cloud...but not all UWA accept it well.
some will hav hot spot...and u'll end up having rainbow effect.
else it could use on any lens to cut off reflection on non metallic surface...etc
ND are use to increase the shutter thus longer exposure.
not sure bout usage on potrait...

ND can be used for portrait, example is when you shoot at f/1.4 1/8000s but still overexposed, that is when an ND comes into play. Of course you can step down to f/2.8 or something, but if you really want the f/1.4 then no choice to use a ND filter.
Thanks guys your input pretty much conclude my question.
conclusion:
Grab 77mm filter for ND and CPL, don't go for 52mm and 67mm?
for the rest use UV, but don't use cheapo uv? am I correct?
