    Tom,
    Another choice brought from the old past is a developer researched and considered by Altman and Henn as the maximum practical limit of high acutance. It was called AH18. They compared with D76 1:1 acutance. AH18 was 40% superior.

    Personally I find the grain on APX 100 on 4x5 to be so small it makes the grain focusser a chore to use. Of course APX is allegedly going away but that's a different issue.

    AFAIK, Agfa has discontinued 4x5 APX 100, not the 35mm or 120 versions. I just received a batch of 120 APX 100 from B&H.

    BTW, I don't consider APX 100 to be grainy. It's just that TMX is virtually grainless, making all other 100 films *seem* grainy.
