Can you explain the dif. between the Cokin A series and the P series filters to me? My main concern is this. If I have a P series filter holder, will A sereis filters fit in it, or will I need a special adaptor of some sort? Or if I have an A series filter holder, with P series filters fit in it or will I need an adaptor for that? Is there a size dif. between the A and P filters?
I have checked the Cokin website, but I didn't see any filter size info...
Any help you can give me would be greatly appriciated.
