I have been using darktable for quite some time now for my NikonD300. I have gotten quite used to it, and the development has been impressive the last year or two.
I recently got an Fujifilm Xpro-1 that I am very impressed with. I do want to work with the RAW(RAF) files also from the Fuji.
I don’t think that I can claim to have a working solution yet, that I am happy with. What I did was to take one arbitrary picture where I had both RAW and Jpeg
