Convert in camera gives definitely good results, but I find it too awkward. Good to quickly load a pic in the web.
:-) What is missing is an application fuji, for PC, with the conversion algorithm used in camera. :-)

I think that right now it is absurd to discuss what is the best raw converter, I tested several, but for convenience ACR is second to none. I find great RFC, so I bought the older brother, pro studio 6. Excellent results.
