I bought 60 rolls of CHS 25 in 120, a few rolls of 820 Aura in 120, and a couple of 50 sheet boxes of the CHS 25 in 4X5. I wish I could buy more, but that's going to be it for now. If I get a crack at 35mm bulk rolls of the Efke 25, I'll pick up a couple of those too.
What about 25 iso film from Ilford? The marked for it it's bigger than for IR, see how popular is Adox CHS 25 (Efke 25), many photograhers love it and buy it, including me. There are not many 25iso emulsions to choose, now Efke/Adox 25 is gone! Make please classic 25iso emulsion and I believe you will have many orders.
Then produce it in sheets, LF & ULF. Like its got a snowballs chance in h***.
Everytime I find a film or paper that I like, they discontinue it. - Paul Strand - Aperture monograph on Strand
It's sort of pointless to stockpile it if you aren't going to use it, but I do understand the feeling, and I'm just as guilty. I still have four rolls of Tech Pan in 120 and 10 rolls in 135, plus a couple rolls of APX 25 in 120. I ought to go ahead and use it.
