Joel,  
	I could understand the restriction on the distance a polarizer is supposed
to be from the taking lens if it were a lens itself, but seeing as how
Polarizers are not lenses, but filters, I cannot see the justification.  I
have used a 95mm circular polarizer and a linear polarizer successfully on
every lens I own by employing step-down adapter rings. No problem. I have
never seen any scientifically based information on the distance a
polarizing filter is from the lens, other than referring to possible
vignetting.  If you have any information I'd be interested......
