Everything else is garbage, including the Canon “sharp cut” filter that costs less than fifty bucks. No kidding, no conjecture. If you use cheap filters, you will never see what your lens can really do. Ever. No doubt that many will respond with claims that their twenty Dollar filter works just fine, but they simply don’t know any better, and have never used their expensive equipment to it’s full potential. It’s akin to a Chevy owner passing judgement on a Mercedes Benz. The Chevy might feel real good, but until you own the Mercedes, you just have no clue.click here
