Title: Really Helpful For Skies and Water
Review: I use the circular polarizer extensively for landscape shots. In fact, I leave it on my lens (Canon EF-S 17-85mm) instead of a UV filter because I use it so much.Pros:- good value.- darkens skies, controls glare on wet surfaces, makes colors pop.Cons:- vignetting at widest focal length (but then again, you shouldn't use it at the widest end due to uneven darkening of skies at widest angle).- doesn't play nice with cokin filter holder (spins when you screw on the filter holder, can be annoying to have to reset it).Overall, this is a good deal for a filter that will really help your photos look better.
