Interesting what Briot said as well:

"Of the two, the Iridient conversion is the smoothest. The capture One shows a more grainy image. These differences may be real or they may be due to my lack of experience using these two converters. I normally use Lightroom and this one my first attempt at using Iridient and Capture One 7. "
"While these tests were interesting to conduct, the best results, which are those obtained with Iridient, are not different enough from those obtained in Lightroom to justify changing my raw converter and giving up the other advantages offered by Lightroom. Another reason for continuing to use Lightroom is that I heard Adobe will be introducing an upgrade that will make it possible to process Fuji in-camera variants in Lightroom. These variants provide users with the possibility of giving Fuji film looks to raw captures and include presets for Fuji Velvia, Fuji Provia, Fuji color negative and more."
