    They might make only one size, because they have the base for 135 from Agfas stock left. So there are no more costs for the base. That's why the film is so affordable. Since the base is very expensive it might be too risky to order bases for other formats.

    The base is not bought or coated in 35mm but in larger sizes, you can use the 35mm base in medium format cameras, in LF it might become a problem. The Impex argument is BS sorry. If they said we only coat and sell 35mm because that's what people buy okay, the base argument is pardon the pun of base. Even Kentmere 100 and 400 are available in 120 size as Rollei RPX.

    I am still not saying that the new Silvermax is not a new film. But I am pissed that they only offer it in 35mm.

    Dominik, are You sure Rollei RPX and Kentmere 100 135 and 400 135 use the same base?
    Adox might have a better outlook about whats selling faster and they might want to sell some 135 in order to finance larger formats operation.

    Thomas, here is the original Agfa APX 100 data sheet which includes the gamma - time curves:

    http://www.maco-photo.de/files/images/agfa_apx100.pdf

    Reading all the "conspiracy theories" here I have to smile and can only shake my head .
    I've used this film. As I have very clearly said, it is similar to APX 100 and Scala 200X, but not completely identical.
    I've already tested it in two reversal processes, the Wehner and Scala process.
    For example Scala 200X in the Scala process gives a light warm tone, but Silvermax has a neutral tone in this process, and a bit less speed.

    Best regards,
    Henning

    Then indeed it is a pity they do not offer other sizes. But Impex surely has a better insight which formats sell well than us.

    I do not understand how you come to the conclusion that it must be an old emulsion, because it is only offered in one size. You still think that it is an old film with new label?

    Hello Dominik,

    No, Kentmere 100 / 400 and Rollei RPX 100 / 400 are definitely not the same films, but different emulsions. If you compare them directly side by side you will see it.
    Independant developer manufacturers like Wolfgang Moersch ( www.moersch-photochemie.de ) and Heribert Schain from Spur (www.spur-photo.com ) have intensively tested both the two Kentmere and the two RPX films and say that the emulsions are different (and therefore also different developing times in the Moersch and Spur developers).
    Another friend of mine has also tested these films in direct comparison and has confirmed the results from Moersch and Spur.

    The RPX films are coated by Harman/Ilfordphoto.
    But as Simon Galley always very clearly has said, they will not offer their original Ilford and Kentmere products to other companies.
    But they do manufacturing for other companies with different products.

    Best regards,
    Henning

    Thank you georg16nik for pointing out the obvious they are not coated on the same base.
    According to Adox the Art series CHS 50 (Efke 50) was coated on the same 100 micron base. According to the Rollei/Maco Datasheet their Retro 100 Tonal was also coated on the same base in both 35 and 120. So using one base for two sizes is possible.
    "they might want to sell some 135 in order to finance larger formats operation" is answered by Mirko on the Impex site "SILVERMAX is only available as a 35mm film and will not be manufactured in other formats."

    Henning I've never used either film but according to the maco-direct site they are the same film:
    "....Sobald die Bestände des Retro 100 verkauft sein werden, bietet Maco den RPX 100 statt dessen an.
    Im Detail:
    Als 135 Kleinbildfilm gemeinsam mit Ilford als Kentmere 100,.." Source: http://www.macodirect.de/rollei-120b...ar-p-2272.html

    Flux: No I am not sure that this is a new film, but I certainly hope that it is.

    I wish Mirko and Foto Impex the best of luck but until it's 100% certain that this is not the old APX/Scala but a new film I won't be ordering any.

    Thanks, Henning. I saw that the SILVERMAX developer is already available http://www.fotoimpex.de/shop/fotoche...75-liters.html
    Whats the smell like?
    Dominik, You know that Efke changed from acetate to poly and that might explains it for CHS and the Tonal films.
    Thanks, Bundesphotograph., last year I shot a few rolls RPX100 120 batch#0331 exp 01/2016 but haven't checked the pdf files in much detail..

    Henning if you follow the link to the Maco-direct (german not english site) this text should have appeared,:

    "Maco stellte bei der Photokina 2010 den RPX100 als einen sehr geeigneten Nachfolger zum Rollei Retro 100 vor. Sowohl als 135 als auch 120.

    Sobald die Bestände des Retro 100 verkauft sein werden, bietet Maco den RPX 100 statt dessen an.
    Im Detail:
    Als 135 Kleinbildfilm gemeinsam mit Ilford als Kentmere 100,
    als 120 Rollfilm unverändert als RPX100."

    Georg I am well aware that they are on a Polyester/Estar Base but even when coating on Polyester one usually uses a different thickness for different film sizes. In case of Tonal and CHS LF Formats are on a different base but not the smaller Formats.
