Affinity does not have a DAM or even one seriously planned. Photo Raw has sort of a DAM, but without import features. Macphun/Skylum will release their Luminar DAM in early 2018. I don't think Macphun/Skylum needs the other two.
Fully understood. I was turned off when Dan promised m43 lens corrections via raw file processing. But they dropped that and try to do with with tables from LensFun. LensFun still does not have the Old 300mm Pro lens that was introduced around 18 months ago.
