Quick qn; do all Hoya CP filters easily rotate/spin, or do they need to be screwed in and out to adjust the polarisation?
Been looking at them on certain sites but can't see any which say they freely rotate, though I recall seeing on here a bit ago that at least some of them do.
Have also seen a Kood one that rotates; anyone got any experience of these vs the Hoya?
