Fujifilm's customers have several different choices of software available with the purchase of their camera. There's the in-house developed Fujifilm X Raw Studio, the Silkypix-based Raw File Converter EX 3.0 and Capture One Express Fujifilm. (Note that there's also a similarly named and also Fuji-specific version called Capture One for Fujifilm, but since that's payware it's beyond the scope of this piece.)
