Hey gang, I'm about to take the plunge and plunk down some serious $ on a polarizing filter. A question, and then some options: Since you need to adjust the polarizer, can you still use a lens hood? All from B&H 1. 77mm Circular Polarizer Multi-Coated (MC) Glass Filter ($145) 2. 77mm Circular Polarizer Multi-Coated (MC) Slim Glass Filter ($165) 3. 77mm Kaesemann Circular Polarizer Glass Filter ($165) 4. 77mm Kaesemann Circular Polarizer Slim Glass Filter ($175) Variables: Kaesemann filters are sealed for harsh conditions and the slim line helps with wide lenses but won't accept a lens cap. Since the cost difference is negligible between the 4 options, do you guys have any recommendations?
