    For Rollei Pan 25, Pan F+ and Efke 25 you can use each High Definition and high acutance developer.

    Some good examples:
    Rodinal 1+50 (or even higher in dilution)
    Beutler developer (Tetenal Neofin Blau), Metol based
    AM50 (Amaloco) high definition pyrocatechine, non staining

    I just was finding out a replacement for AM50 due to the fact this Amaloco developer is discontinued and Neofin Blau/Blue is rather expensive.

    So I tried the Beutler original fomulae after some specific recommendation and information from Tom A. (from the RF Forum) who has a lot of Beutler experience.
    It's a very easy to make yourself developer which is for me a perfect replacement of the AM50.

    Here an example of Rollei Pan 25 in AM50 1+29:



    and here an example of Rollei Super Pan 200 in Beutler 1+1+10:



    Both images shot with the M7+Summicron 2,0/50mm

    The Fomulae:
    Solution A:
    1g Metol
    5g Sodiumsulfite
    fill up till 100ml (water).
    Solution B:
    5g Soda (Sodiumcarbonate)
    fill up till 100ml (water)

    Beutler produces a raisor sharp image with acceptable grain. In the 50's the Beutler formulae was very often used on the Dr. Schleussner/Adox films, with are the actual Efke 25-50-100 single layer films from now.

    Some pricing (in the Netherlands):
    Tetenal Neofin Blau/Blue 5 small bottles / 5-10 films: Eur. 11,50
    Amaloco AM50 60ml (for 3-4 films): Eur. 2,70
    Rodinal 500ml (for at least 50 films): Eur. 12,00
    Beutler see above receipt : Eur. 0,05 / film

    I have the following list:
    1. Ilford Pan F 50
    2. EFKE 25
    3. Rollei Pan 25

    However, I am not sure what developer should I use for these films. I am also not sure about the development time for these film, cause there are so many versions online. I am looking for some recommendation for B&W developers and developing time for these film.
    By searching the Internet, Diafine looks like the easiest way to develop these films. Only need 3 mins in two develop bath. Anyone have good results using Diafine? Any other Suggestions? What about stop bath and fixer?
    Hope someone can give me some hints, and helps on this.

    Many Thanks in advanced.

    I've used a 1-3-3 formula with film. That's an Ansco 120
    print developer formula ratio minus the 120's bromide.
    I break all formulas into ratios. FX-1, 1-10-6.

    Very good Dan, never thought of it that way. Makes sense and allows quick mental comparisons of Beutler type devs.
    I always lump them together but that way seems more informative as to the probable outcome.
    Thanks.

    Dan,

    Does 1-3-3 mean 1 Solution A, 3 Solution B, and 3 water?

    Diafine will probably work fine. I've seen some excellent Pan-F work developed in Diafine. But to get to know the film, I would recommend using one of the developers the manufacturer recommends for the film, particularly if you already have experience with it. D-76/ID-11 (usually 1+1) is frequently one of the recommended developers. Once you know how the film works with the standard developer, you can experiment with others and have some basis for comparison.
