  • Support for OM System (former Olympus) OM-1 RAW files

    Hello, I used Canon for 40 years. Switched three years ago to Sony and Olympus, so far so good. I use ACDSEE mostly for browsing and sorting my files and choose which to keep and delete. I use ACDSEE for a very long time. Early this year I upgraded my Olympus camera to the new flagship OM-1 for specific use. I asked ACDSEE to add it to the supported cameras several times now. All my editing software has been updated adding this camera, unfortunately ACDSEE still hasn't. I can't believe I'm the only one using that camera in ACDSEE.

        Adobe DNG converter is available as a free download. You don't need Photoshop.

        The current version (at time of writing) is 14.4.0.1121 and it is able to process the 5184 x 3888 ORF raw files from the OM-1 camera, however it does not apply lens correction (at least for the OM 12-40mm F2.8 II lens used in the images I tested), and the Lensfun correction used by ACDSee doesn't currently support that lens, so correction has to be applied manually in ACDSee Develop mode.

          Re LensFun: alternatively one can copy paste the older 12-40 profile within the olympus lensfun XML data file and change the lens name (to that shown in exif). The lenses aren't so different that it would make much of a difference (and having created my own lens profiles, I learned that lensfun data isn't all that accurate anyway). I am still hopeful ACDSee will some day support embedded lens correction data like other apps do.

            You're not the only one, but the cameras aren't coming out very fast either. I've submitted a ticket also as a reminder. Did you provide sample images to ACDSee as suggested?

              Yes, a couple of times. Unfortunately nothing yet...

                I use DxO PhotoLab for RAW conversion.

                  I only use ACDSEE for image browsing, sorting and managing. I do have PS, DxO PhotoLab and some other software to edit. That's just my workflow.

                    For those who want LensFun support for the OM-1 and see their lens profiles automatically recognized when using converted ORF to DNG (until ACDSee publish a RAW model for the OM-1), replace the original mil-olympus.xml file located in the LensFun sub-folder of the main application folder (recommend that you keep a backup copy of the original file) with the corrected file in the attached zip (it need not be renamed). Once Ultimate is launched again, the lens profiles will be recognized (see image below). This file adds the OM-1 to the list of supported cameras, AND also fixes a few bugs that prevented some lens profiles from appearing (I've sent the corrected version to ACDSee and LensFun but they never used it). Disclaimer: USE AT YOUR OWN RISK (though there isn't any risk really it's just an xml file; if it doesn't work, simply put the old file back if you kept a backup copy). I didn't add the new 12-40mm MkII since I don't have access to the exact EXIF data. I can if someone does provide me the exact EXIF Lens Info, but it will be using the original 12-40mm correction data, which is probably close enough until a new profile is created.
