I recently got a Polarizer as a gift from someone and decided to read a little about them on the forum. I never even thought about the fact that all polarizers weren't created equal and since mine was $20 i am pretty sure it's not all that great. Now i am curious though, are all UV filters created equal or do i need to get different ones?Thanks and if you could link a good polarizer and UV filter from B&H photo? I am assuming they ship to APO addresses but my connection here is horrid and it takes me about 5mins per page.Ps. Random wide angle question Sigma 10-20, or Canon 10-22? which is better?
