Many thanks for all previous advice - and Merry Christmas to everybody.
Finally managed some shots on the water this morning in full sunshine with my 500D with 18-200mm f3.5-5.6 IS. The shots look quite good, however, I suspect I should be using a polarized filter ??
What is a UV filter for ?
Assuming you recommend the polarized than is a Hoya OK and if so do I get the CPL or pay more for the Pro1 Digital CPL, or even more for the Super HMC CPL ??
I know you usually get what you pay for but whats realistic for my current set-up ?
