The FinePix X100 is aimed at the professional photographer or keen enthusiast looking for exceptional quality pictures from a compact camera. It is designed to appeal to the millions of DSLR users who need a slim back-up camera for high quality in-fill shots when the use of a bigger SLR system is either inconvenient or impractical. Or, of course, it can be used as a professional's only top-end camera, if size and versatility are the primary considerations.
