The pricey Fujifilm FinePix X100 is a bit of an oddball. Though we traditionally call models like the Panasonic Lumix DMC-LX5 or Canon PowerShot G12 "large sensor" compacts, their CCDs are relatively tiny compared to the APS-C-size CMOS in the X100. ILCs like the Sony Alpha NEX or Samsung NX series have APS-C sensors, but they're higher resolution with smaller photosites. The X100 also sports a prime lens with a 35mm-equivalent focal length, while the less expensive, more mainstream-focused compact models incorporate zoom lenses; no matter how short the zoom range, a prime will usually deliver superior sharpness and clarity. But you can stick a nice prime on those ILCs as well.
