For sale, 4X5.650 Pancro Mitchell Diffusion set "A"' "B"' and "C". Excellent condition, no pits or scratches. $675.00 for the three filter set, sells new for $1050.00, see link http://www.pancro.com/#/storecontact/4529714635. These filters work great (subjective!) with film and digital. This is my third set and don't need that many sets. No filter pouch, free shipping. Thank you.
