Re: Circular Polarizers, A Filter You Need

Both polarizers work the same way, just the circular has a second layer 
to depolarize the resulting light. The polarizing part does the same 
thing, so there should be no difference, all other things being equal. 
However there are different materials used and so they can vary 
significantly between brands and even within brands if the manufacturer 
has changed process.

Some cameras will be more sensitive to linear polarization than others, 
but if you were buying now it is probably not worth the risk and just 
get a circular one.

Cheers,

Wayne
