Missing Metadata infos

cwort
The metadata shows me informations about the focal length and aperture from the used lens. What I can't find is the field "Lens type". The fantastic tool GraphicConverter shows these information in the metadata field "Lens type" (or "Objektiv Typ" on my german version), in my case "SMC PENTAX-FA 1:2.8 135mm IF" as an example. Is there a possibility to find these infos in C1 9 too?

    I can see information about my Canon lenses in the metadata.
    The information is shown under Vendor specific --> Lens e.g. EF28-70mm f2.8L USM .

    So this might be a Pentax specific problem.

    May be it is a Pentax problem. But I don't think so because of the fact that other apps (GraphicConverter, Aperture, ExifTool on a Windows machine) can show these info. What I see under Vendor specific --> Lens (Herstellerspezifisch --> Objektiv on my german system) is just the focal length in both cases, supported and unsupported lenses. I should ask the support.

    It is a Phase One Problem! Even Apple's Photo app which is for free, shows lens info. For several years phase One refuse to solve this.

    Maybe not.

    Even if some cameras may provide lens name in clear text, it is apparently not the case for all cameras. A recent thread over at Camera Bits (http://forums.camerabits.com/ , "General Discussion", subject "Lens Variable") covers a similar issue as this thread does.

    I think the Photo Mechanic guys (Kirk Baker and Dennis Walker) correctly explain how lens information is kept in so called maker notes in metadata. Depending on camera manufacturer, information is more or less scrambled. Unscrambling (decrypting) maker notes may not be difficult, but nevertheless raise legal or perhaps ethical questions. In said thread Dennis Walker writes: "To be clear, it is not a technological issue but a legal one."
