I'm offering up for trade a Hama branded, multicoated KR 2 (Wratten 81 A equivalent) filter. When enspected very closely, the coating does have some hard to see blemishes, but I wouldn't hesitate to use it for critical applications. I'd like to receive a 39 mm medium or deep yellow or orange or green filter, or a 49 mm ND or medium or deep yellow or orange filter, or a cable release or a roll of film (B&W or E6) in exchange. Don't hesitate to PM me if you have something else around you don't need. Thank you.
