I was attracted to the cokin sytem since I like to make landscapes and HDR's. I
read a lot of
information but there's one thing not clear: I use a Sigma 10-20 mm lens with a
77 mm filter
diameter. Would the cokin P holder fit? My question is because I saw a diagram
of a cokin P
holder where the inner diameter is only 73 mm. Or would I have to get the Pro or
other
sytems? Thank you and regards, Bo
