I have 3 Tiffen 3.25" x 5.65" Graduated Neutral Density (ND) filters, in graduated densities of .3, .6, .9.
These are OPTICAL GLASS not resin. New prices depending on where you look and the density go for $170 - $300 each. I'm not sure they are even made any more, as the usual dealers only had a smattering.
Could be the price
I'll sell for $100 each or all three for $250 $199 net to me. Free shipping to lower 48.These are in great condition, used lightly. I have 2 black canvas fitting cases which will go to the first and second filters sold, free.
I have a Cokin filter holder for these filters with one 67mm adapter ring--other sizes available on line--$25 or I'll give this free to anyone that buys all three filters at the same time.
