    .
    My understanding is that the changes of speed rating which applied to all films at the time (was it the late 60's of 70's?) were the result of changes in measuring definitions by the relevant Standards Organisations (probably ASA and DIN ratings at that time). There were no actual changes in the emulsions.

    I think it has been said that it was to allow for the more accurate meters and cameras which were becoming available, which made the previous allowance to avoid the risk of underexposure no longer necessary..

    Perfectly right. That change for ASA and DIN took place in 1960 rsp. 1961.

    According to the Macodirect newsletter I just read, RPX 25 is being introduced in both 120 and 135 formats.
    Also the existent RPX100 and 400 get a "face-lit" by being packed in boxes! Great to see boxed rolls again!
    The entire RPX family in new boxes will be available from January 2014.

    Given that both RPX100 and 400 are coated by Harman/Ilford Photo, I wouldn't be surprised if RPX 25 is made by the same people.

    One could think so. And that packaging leads in the same direction. But not the colourless base.

    What is meant by "nominal sensitivity"?
    As far as I am concerned it is a 25 ISO film. They always say there is a speed reserve. Otherwise nobody would buy it.
    You know all developers are "fine" grain working.

    Could be. The times in Rodinal are the same and going by memory, the D-76/ID-11 times are the same, too. However, Ilford says they will no longer rebrand their films. Ilford will make a new emulsion for someone, though. I'm as curious as the rest of you and wait to try this film when it hits the US and also await others findings.

    Brand new emulsion ? That's a good sign. It looks, like demise of Efke films made a hole and it is very smart by Harman to fill it up. Just wonder, if they will make enough of it, for some of it to reach Canada.

    This has been discussed to death with the previous RPX films, if they were the same as Ilford Pan 400, or Kentmere 400, or Kentmere 100...and the answer (has been) is that it's not. They are new emulsions. I think the same goes for this new film.

    Anyways I'm really curious and will try this new film next time I place an order to mack. Not sure how to use it in our dark winter here, but I will find a way

    Ok. 10 rolls of Rollei RPX25 120 on the way from MacoDirect. I'll see how it compares with my EFKE R25. Maybe this will be the film I have been waiting for.
