For Sale: two Tiffen 4.5" round filters, old stock, like new in box. 85B-POL & FL-B, $95 for both, shipping included to lower 48. PayPal preferred.
Filters are in their original tissue, inside their original Tiffen cloth/velcro pouches, in their original boxes. Filters are +/- 20 years old, but have been stored, unused, in my equipment closet at 8500' in the cool, dry Colorado climate. No scratches, no cleaning marks, no rim dings.
I am a retired still photographer, and had rigged the mat box for my 8x10 view camera to accept 4.5" rounds. Had quite a few, but I've sold most of them with the camera. Since tungsten-rated sheet film has disappeared, these two were 'orphans'.
85B-POL combines daylight conversion filter for tungsten film with polarizer in one filter. FL-B is for shooting tungsten stock under fluorescent lighting. Tiffen's current 4.5" 85B-POL is $414 at B&H, (http://www.bhphotovideo.com/c/product/367434-REG/Tiffen_412SR85UPOL_4_5_Round_Combination_85.html). Their current FL-B is $196.
