Originally posted by 77me I wouldn't count on PhaseOne to do anything no matter what Ricoh does. They don't support pentax exif information very well and they can add support for all kinds of other cameras, but not the K-1mII. I gave up and moved on.
I was one of the first buyers of the K-1 and used Capture One Pro although it didn‘t support the K-1 officially. Simply shoot DNG. I guess you‘ll be able to work on this raw basis. - I was happy with the K-1 DNG results I could achieve. For Pentax DSLRs DNG is a native raw format like PEF (no discussions about that). It should work. I didn‘t try DNG files from the K-1 II but some DNGs of Ricoh GR III that also isn‘t supported officially. I downloaded the DNG files from the web. After Import in C1Pro ICC Profile „DNG File Neutral“ is set automatically. On this basis I got nice results and if you are familiar with C1Pro Editing you should too - IMO. ;-)
I'd like to add something concerning exif-data in Capture One Pro:
If you want to see the name of the lens of your captures, you have the option to install exiftool. Then create a batch file (windows) or bash script (mac, linux, unix) as a workaround containing the following line:
exiftool -overwrite_original '-exif:LensModel<${Composite:LensID}' .
This copies the pentax specific field to the general exif LensModel field for all images within the folder where you are. If you want to preserve the original file untouched then delete tag "-overwrite_original" from the line.
The exif tag LensModel is shown in Capture One Pro. This is the only "problematic" exif tag I remember.
