Hi guys,
Dunno if its the rite places to post these..... i'm just curious abt 2 question:
1) What is a WIDE BAND circular polarizer?? as we know what does a circular polarizer did already.
2) Is there certain relationship between focal length and polarizer filter? i heard there is some relationship between focal length and ND filter, but not too sure abt it.
Can any kind soul point point to any link or explain?? maybe that had been discussed but i no see in recent posting anywhere.. ;p
thks for enlightening....:thumbsup:
