    I had a same problem, I develope apx 400 in rodinal 1:50 and 1:25, but whole time a was not satisfied. So I as read something and find that is D 76 (the main developer) is best for little grain for that kind of film. I try and the results are great. Contrast is normal and grain is normal for that kind of film. I was develope in dilution 1:1.
    Does anyone have some details for developing apx 400 in higher sensity (like 1600 iso), if You have some experiments do You have results? In my book from agfa I have only developing times for apx 400 on 800iso.
    Thank You

    I am not crazy 'bout the APX400, but used with Rodinal you'll get great grain.
    I like Rodinal with 400 ISO films as the grain is so distinct vs. other devs that gives fluffy grain, and less sharpness.

    Grain is what we live for

    What time did you use for D76 1+1? The massive development chart only lists a time for stock D76 for the new version of APX400.

    I have two times 14 min and 14,5 min. I have good results on 14,5 min on 20C

    It's really not that grainy. Not nearly as grainy as Tri-x/Rodinal. I am of course talking about the "new" APX 400. I would recommend Rodinal 1:25 with this film, at 1:50 it starts getting quite flat. I've pretty much given up on this film, though it is beautiful in Pyrocat HD, and quite nice in Diafine under very contrasty lighting.

    What time have you used for APX400 in Rodinal 1:25? The Massive Development chart lists a time of 30 minutes for APX400/Rodinal 1:50 which, from my experience is about double what it should be. Hence, I do not completely trust their value for 1:50.

    The time of 30 min for 1+50 on the Massive chart is Agfa's own recommended time. Agfa also recommends 11 min for the same dilution, so take your pick. They (Agfa) don't tell you if the times are for the old or new APX 400. The newest bottles of Rodinal I have say 11 min for 1+50.

    As far as the times on the Massive chart go, a great many of them are manufacturers recommended times. The rest are just what someone has decided they liked, and wrote in to suggest it be included on the list. At best, they are a place to start.

    Agfa's pdf files have had some errors in the last couple of years. I have downloaded and saved them, because I was looking at choosing a 400 speed 120 film. Now that Agfa's supply of 120 size film is a matter of doubt, I have chosen another film.

    From my reading of their files, and ignoring really obvious typographical errors, it seems that their recommendation for Agfapan 400 (new*) in Rodinal 1+50 is:

    Rotary Processing:
    gamma 0.55 15min
    gamma 0.65 30min
    gamma 0.75 no entry for this value

    Small tank, tray
    gamma 0.65 30min (same as rotary? seems a bit odd to me, since for 1+25, there is a big difference between inversion and rotary, i.e. 15min as against 10min)
    no times for other contrast levels.

    Since 0.65 is rather higher than most of use would aim for, it seems strange to offer a time for 0.55 for rotary, but not for small tank (inversion etc). For normal contrast, I would try something like 15min.

    * new emulsion started with manufacturing batch number 450 for 35mm, and 260 for 120 roll film.

    What all of this means is that one needs to do some testing with this combination!

    (The 11 min time was their recommendation for the old emulsion of Agfapan400 in Rodinal 1+50 in small tank (not rotary). If the new bottles of Rodinal still have that time, they are either not new (not a problem, of course) or Agfa's labels are not updated very efficiently.)

    This is what my new Rodinal Bottle instructions tell me:

    AGFApan APX100. ASA100. Rodinal 1+25 at 8 min. Rodinal 1+50 at 17 min. 20°Celcius
    AGFApan APX400. ASA400. Rodinal 1+25 at 7 min. Rodinal 1+50 at 11 min. 20°Celcius
    Agitation: Continuous agitation during first minute. Afterwards every 30 seconds.

    This is what my up-to-date TAFE College handout tells me:
    AGFA APX100. ASA100. Rodinal 1+100 at 20 min. 20°Celcius
    AGFA APX400. ASA400. Rodinal 1+100 at 17 min.
    Continuous agitation! 24°Celcius

    AGFA APX400. ASA200. Rodinal 1+100 at 15 min. 20°Celcius
    AGFA APX100. ASA100. D-76 1+1 at 13.5 min. 20°Celcius
    AGFA APX400. ASA250-400. D-76 1+1 11 min. 20°Celcius
    Agitation: Continuous agitation during first minute. Afterwards every 30 seconds.

    This is what the new AGFA film box instructions tell me:
    (Attention: New developing times!)
    AGFA APX100. ASA100. Rodinal 1+25 at 8 min. 20°Celcius
    AGFA APX400. ASA400. Rodinal 1+25 at 10 min. 20°Celcius
    Agitation: Continuous agitation during first minute. Afterwards every 30 seconds.

    I have also heard that developing AGFA APX in Ektol is supposed to give beautiful results. Anyway, I'm about to find out in the next week or two. I'll be developing in both Ektol and Rodinal.
