Apologies if this topic has been done to death, but have spent all morning reading reviews/posts/etc and feel like I'm going round in circles.
Am wanting to purchase circ polarised filter for Canon 10-22mm. Have been playing with Cokin P series nd & ndg filters for waterfalls & seem ok so far (am just novice to the filter world)
From what I'm reading, I should probably stay away from Cokin P series CPL due to vignetting - correct?
Can also see advantage of Hoya screw-on CPL rather that Cokin drop-in filter when I'm moving from place to place - correct? (should also mention that other lenses are 77mm so use on them is not an issue)
Am I better to go with the thinner Hoya Pro1 when using wide angle as opposed to basic Hoya CPL? (again to avoid vignetting?)
If I go Hoya Pro1, should/could I stack onto UV filter (which i'm using mainly for lens protection) or remove UV?
Any help and advice gratefully received.
