The Fujifilm X100S Digital Camera features a 16 megapixel APS-C-sized X-Trans CMOS II sensor and an EXR Processor II image processor to provide high quality imagery and exceptional camera performance. The combination of the sensor and processor enables a native sensitivity range from ISO 200-6400, which is further expandable to ISO 100-25600. Fujifilm's proprietary X-Trans sensor uses a unique randomized pixel array in order to avoid the use of a resolution-reducing optical low-pass filter, therefore providing images with the utmost sharpness and clarity. This imaging system is benefitted by the Intelligent Hybrid AF system, which uses both contrast- and phase-detection methods to acquire focus quickly and accurately. The EXR Processor II also delivers fast performance speeds to all aspects of the camera, ranging from quick startup and shutter lag times to a fast 6fps continuous shooting rate.



The X100S incorporates a unique Hybrid Viewfinder that blends the capabilities of both optical and electronic viewfinders into a single entity. The optical viewing benefits include a clear, natural method of composing your scene with the added benefit of exposure and camera settings being displayed in the perimeter of the frame. The electronic viewing method utilizes a 2,360k-dot LCD monitor to provide clear, sharp live view monitoring with the ability to previsualize focus and exposure settings. You can toggle between both viewing methods quickly and easily using a lever located on the front of the camera body. Manual focusing capabilities are greatly enhanced when using the electronic viewfinder in connection with either the Digital Split Image function or manual focus peaking; both of which aid in acquiring exacting focus. In regard to auto focusing, a unique Intelligent Hybrid AF system employs both contrast- and phase-detection methods to focus accurately and as quickly as 0.08 second.



A built-in 23mm f/2 fixed focal length lens is used and provides a 35mm-equivalent focal length of 35mm, which is ideally suited as an everyday-use wide-angle lens. The fast f/2 maximum aperture benefits both low-light shooting as well as control over the focus in the image. The lens has been intentionally designed as a non-interchangeable, non-collapsible, and fixed in focal length in order to provide the highest quality optical performance possible. Its construction includes a single double-sided aspherical lens and features a Super EBC (Electron Beam Coating) to reduce lens flare and ghosting. A three-stop neutral density filter has also been built-in to allow greater control over your exposure settings and selective focus applications.



Full HD movie recording is supported up to 1920 x 1080 at 60fps with a 36Mbps bit-rate for clear, fluid-looking videos. Focus can be manually controlled during recording, while audio levels, white balance settings, and Film Simulation modes can also be applied to refine the overall appearance of your movies. Film Simulation modes make use of Fujifilm's history of producing both negative and slide films, and allow you to apply those films' characteristics to your digital imagery to better suit your intended look.



Surrounding the camera's technology is an elegantly designed camera body that features die-cast magnesium top and bottom plates, precision-milled metal camera controls, and a durable synthetic leather body wrap.
