    Adox chs 50, ilford panf 50 or fuji across 100?

    Which one would you prefer?

    I guess PanF has more tonal range but which one is sharper? Across 100 or chs 50?

    Which one has better result with colour filters?

    The Adox is the one made by Efke, if I remember right, and its discontinued, so I'd not bother with it.

    I've used a lot of Pan-F and Acros. Acros is sharper and has less grain. That said, Pan-F is a much more beautiful film. I've never liked the flat midtones that Acros gives. Acros is my choice for dim light, long exposure work, because it has so little reciprocity failure. I've used it for exposures up to 5 minutes in length with only 1/2 stop compensation needed!

    For normal work, Pan-F is a nicer film in my opinion.

    Pan F is sharpest of the 3, it's slower by a stop as well. Adox CHS 50 is closer to being a 100 EI emulsion the 50 in it's name refers to it's Tungsten light speed.

    As Adox/EFKE 50 is no longer made I'd personally go for Acros of the two as Pan F is limited to 35mm & 120, however if I only shot miniature formats I'd standardise on Pan F.

    One of my friends shoots Pan F and develops in Perceptol diluted 1+2 - the results are outstanding.

    Strange that Chris and Ian have opposite views on which us sharpest, I still think PanF is sharper as Acros just seems to have edge blur but I know there must be user error as I feel it's worse than even Tri-X/HP5 so there must be something I'm doing wrong but I still can't figure out what.

    PanF processed properly is sharper, but it's not as forgiving as Acros, it's also finer grain.

    I have used across developed with radinol and it looks very sharp to me. The blacks are nice and deep in studio. i get a very nice dark sky with red filter.

    But PanF seems to have more shalow blacks and less contrast and not as sharp. Maybe if I try with a different developer?

    Which developer whould you recomend for sharper results with PanF?

    I guess the sky doesn't get as dark on PanF with red filter because its higher tonal range. Does ut makes sense?

    To get the best from Pan F it's important to do your own film speed/development time tests. These will affect the shadow detail as well as the contrast and it's important to get the balance right.

    Slower films need careful handling to get the best sharpness, you have to use slower shutter speeds and wider apertures and that doesn't help. So a good tripod and mirror lock (if you can) makes a huge difference.

    Way back in the early 1960's Geoffrey Crawley wrote about getting the ultimate in sharpness & resolution with Panatomic X (but applicable to Pan F as well) and he commented that you needed good lenses, no vibrations, optimal exposre etc.

    I repeatedly found Acros to be finer grained than Pan-F+. Of course it's tonality is quite different. Different curve shape. Different type of film and I don't think comparing the two makes a lot of sense.

    As for which film is "sharper", I highly doubt anyone on APUG is in a position to make any such assessment. It is very difficult to do. It also depends on the developer and processing.
