Rollei RPX 25 - Light Leakage?

  1. I just picked up some Rollei RPX 25 in both 35mm and 120. For the 35mm version, I'm wondering if this film has to be loaded in subdued light. With Rollei's previous generation of B&W films, even the non-IR films, there would always be some light leakage into the sprocket holes of the negative, which usually wouldn't reach into the area of any of the individual frames, but sometimes would.
    So long as I loaded the film in a changing tent, or inside of a backpack, things were alright. I suspect there was leakage because of the plastic canisters Rollei was using. I'm just wondering if the RPX films behave the same way.
     
  2. I think it would depend on the base that the emulsion is coated on. I noticed some slight sprocket fogging with a roll of Rollei R3 that I shot a few years ago.
     
  3. After I first noticed sprocket fogging with Rollei film, I always took to loading it in subdued light or total darkness. I'll just keep that up for now.
     
  4. Also noticed a few fogged sprockets on a roll of Rolleipan 25 I just developed. It's from a bulk roll. Maybe I need to load
    that in reduced light as well.
     
  5. Yeah, I've gotten fogged sprockets on Rollei Pan 25 as well. I now load all Rollei film in the dark, or subdued light. I've never had leakage issues with their 120 films tho.
     
  6. Rollei RPX25 is made by Harman/Ilford
    it should be a high quality product and
    you are less likely to suffer light piping.

    Many Rollei films are based on Agfa
    aerial film material which has a clear
    pet base and is very prone to light
    piping.

    The old Rollei Pan 25 was made by Efke
    and they had questionable quality
    control. Sadly Efke are no more hence
    the replacement with RPX25.
     
  7. Thanks for the info, Simon. I wonder if anyone will pick up production of Efke's IR films, or is there just not enough of a market for that?
