  1. If I use a Polarizer does that negate the need for a UV Filter?
  2. If I use a Variable ND does that negate the need for a Polarizer?
  3. Is there a negative effect from using several different types of filters let say a UV, Polarizer and Vari ND all at once or is there a net positive effect from using all 3?
  4. What is the best pattern to organize the filters on the lens if using a variety of filter types. ie. Vari ND 1st, then Polarizer, then UV?
  5. Is it best to buy the best SET of filters from the same brand or the best individual filters from different brands.
  6. Is there some kind of rating system for Filters that can be used to compare their effectiveness? ie effect on sharpness, color etc. How would someone actually choose one filter from another to find the best one if there is no rating system? Is there a really reliable resource on the Web?

Sorry if there is some thread that covers this, but I haven't come across any that concisely address this topic.

But now I need for any hack to shoot Corals in blue and UV light to show the fluerense of them. The simple Pentax wp making it easy,to improve the white balance The film made Pentax WG3 the fluerense of coral at the end fim

But I can not do it in Panasonic GH2 or any other DSLR camera, the white point must be higher then 20000K and improve the white point in dark blue. If you have some idea, or any patch for this problem...

The bad news, my PA dropped it out of the bottom of the mattebox with the tray and two of the corners are damaged. It doesn't show up in any footage but it's there. Check out the pics. The rest of the glass is perfect. $150+Shipping. I'm in the US.
