I used a smal saw to simply cut off the front two slots, making the risk of vignetting much smaller. I use that slot for a graduated ND filter. > >Also, I'm curious as to whether it's possible to use a (screw on) SinghRay >thinline gold/blue polariser together with an nd grad on a Cokin P, since I >understand the thin g/b doesn't have an outer thread? If that filter does not have an outer thread you won't be able to mount the Cokin-P holder properly. It needs a small metal ring that screws into the lens (or filter) thread. You then slide the plastic holder on that ring. There are rings in several diameters to accomodate different lenses. You can't mount any filter to the front of the Cokin either. (would cause massive vignetting anyway :-) > I haven't used the >Cokin P holder before, and I apologise in advance if all this sounds overly >silly. No problem. There are no dumb or silly questions :-) Regards, JvW ------------------------------------------------------------------ Jan van Wijk; http://www.dfsee.com/gallery
