I am sort of confused on this issue. Supposedly you cannot use linear polarizers on most digital cameras since it affects, among other things, the autofocus. Is the FZ20 an exception to this rule? Has anyone used both linear and circular polarizers with this camera. Any comments w/b appreciated.

I would presume it would work in your manual focus mode?
Funnily enough I was looking for soem for my FZ5 today and leanred that I must get the more expensive circular one!

FZs do not require a Circular Polarizer.

Both Polarizers work on the FZ. The FZ does not have split beam mirror focus which requires a CPL. But why spend the extra money for nothing. Check out ebay. They have Linear Polarizers in 55, 58 and 62mm.

I have recently bought a 62mm LP (Prisma) in Italy for 20 Euro.

It works fine and fits on top of the FZ20 lens (with no adapter) but It will fall if you leave it on.

Fixed on the 72mm FZ20 adaptor it vignettes up to c. 2,5x zoom, but I plan to take a Phayee or Pemaraal for that, cause I already have a 6T.

No problem with focussing and it can be turned to vary the polarizing factor from 1x to 3x.

Great for enhancingclouds shapes and for dealing with high contrast and wide dynamic range scenes.

Sounds like a good price and the adapter changeshould solve your problem.

I second the recommendation of sticking w/ a Linear Polarizer, it works fine w/ the FZ20. I myself use a Raynox 52mm LP, i got mine as a package...LP, UV, Adaptor, lens cap and pouch for $49.99 (incl tax and ship of Ebay). So far I have used friends circular polarizers, and the effect is not as dramatic as linear, it could be my preference...but if you can use both use the LP its pretty straightforward and gets you the maximum effect for a cheaper price.

the only reason to really get a CP, is either cause you already have one or got a great deal on one...thats it

You have discovered the truth, PLs work better then CPLs. The added film for split image mirror focusing systems degradespolarizer performance.
Did you know that you can use a polarizer as a variable ND. Stack two PLs and you can achieve an ND 6.
