Recent upgrades to Aperture have resulted in the EXIF data no longer identifying the Leica lens used. EXIF only identifies "50mm" for example, whereas it previously identified the lens as "Summilux-M 50mm f/1.4 ASPH."

Apple professional support was unable to figure this out and never contacted me, despite promising to do so.

Has anyone solved this problem?

    Look at this thread for a work-around

    Re: Leica lens names don't show up in metadata. Any suggestions?, also at William Lloyd's post in the thread for an explanation.

    Thanks, Leonie. Aperture displayed all Leica lens info in the EXIF data until a recent update, then it stopped doing so. That is the problem.

    I'm seeing the same thing.  I just ran exiftool on a RAW file and see this:


    ExifTool Version Number         : 9.12


    Lens ID                         : Summicron-M 35mm f/2 ASPH.

    Red Balance                     : 0.583497

    Scale Factor To 35 mm Equivalent: 1.0

    Shutter Speed                   : 1/16

    Circle Of Confusion             : 0.030 mm

    Field Of View                   : 54.4 deg

    Focal Length                    : 35.0 mm (35 mm equivalent: 35.0 mm)



    I don't really know the EXIF spec so I don't know whether "Lens ID" is the standard field that should be used.
