Efke 25 was unique - very long scale, relatively high contrast, very fine grain, orthopan sensitivity.
No other fine grained film had these characteristics. ACROS is about the closest. Pan F, but comparison,
is ordinary pan and has quite a short straight-line to the curve. And so-called micro-films are really soot
and chalk when it comes to the toe and shoulder, and often have poor edge effect. So I don't see any
direct substitute on the horizon yet. I still have quite a few rolls of Efke 25 120 in the freezer. I liked it
under strong lighting in the mountains. But you gotta be carefully loading it - it edge fogs easily.
