Here is what I have in the way of Ektar 25:
- Four rolls 35mm, emulsion matching and identically stored, expired 05/1998
- Four rolls 120, emulsion matching and identically stored, expired 01/1998 (One box is splayed, but the spool itself is still wrapped.)
All are from the collection of a local commercial photographer (Todd Johnson) who a friend used to work for. Knowing Todd's level of technical obsession, I am assuming he stored them properly until I got them in 2006. They have been frozen since I got them. I have shot the 35mm and it seems OK for the most part, but perhaps a slight bit muted and with a very slight color cast. I shoot this film when I want that look, not when I want absolutely perfect color.
Here is an example (a pic of my own 3-print series on the wall at a group show, with my and my father's reflection) shot unfiltered in tungsten light hand held with my IIIc Leica, scanned with a Nikon scanner, and color corrected in the computer. I happen to have this example scanned because I needed to send it to a family member at the time.
I'm not so sure I want to get rid of the 120 just yet, but make me an offer on the 35mm if you want it. I don't think I need the lens you are offering, though. But I shoot Canon and Nikon manual focus cameras, and Mamiya medium format stuff. Or make an offer of money.
