Polarizing Filters

I got the B+W   77mm Kaesemann Circular Polarizer MRC Filter  before my trip to Hawaii in September last year and loved it. It was my first time using it. It really did a great job on the skies and water.

If you've got cheaper lenses, probably not necessary to spend $100 on one, but I was using my 17-55 2.8 and wanted a nicer one on there.
