Best Circular Polarizing Filter

The polarisation effect can be controlled by turning the filter itself, so if your front element rotates the polirasation effect is sort of out of (your) control. I think you need to read little more on this, still doable with manual but not conveniant since the focus ring on the 18-55 is already pretty small. Double check this if this works for you, just my 2cents ok, trying to help.
