Thank you Kirk,
I changed to Adobe settings, but it didn´t had any effect on the files when using CaptureOne. Still missing datas and also some words changing the spelling (e.g. n instead of b). I usually convert files within C1 and C1 now doesn´t tranfer the data properly. XMP sidecars are also not very appealing to me, as I have now more and more files in my folders. All of this wasn´t the case before, with my older 5D´s.
Any thought´s?
Thanks
Ralf
