I have a pair of lovely Heliopan filters, 67mm thread mount in orange and red. Perfect for black and white photography. These are solid in the hand and obviously of good quality. Unfortunately I don't own 67mm cameras or lenses anymore so these have to go. $50 shipped in US or Canada, paid by Payal. Canadians can pay in CAD if they use Interac transfer. International shipping possible. Will post pics if required.
