The black 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 1080p 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.
The X-Trans sensor also pairs well with the EXR Processor II to provide highly effective noise reduction and a clean signal-to-noise ratio. This enables smoother-looking imagery that becomes especially apparent when photographing in low-light situations with an expanded sensitivity range of ISO 100-25600.
Three focus modes are available (AF-S, AF-C, and M) for greater control over how the X100S achieves sharp focus. When working with autofocus, the AF area is divided into a 49-point matrix in order to gain clear focus of any type of subject matter. Additionally, a built-in AF assist lamp is available for aiding the focus system when photographing in low-light situations
The simple lens construction is comprised of just eight elements within six groups, including a single double-sided aspherical element to reduce aberrations and improve sharpness. Lens elements also feature the Super EBC to reduce lens flare and ghosting while maintaining image contrast and color fidelity.
A three-stop neutral density filter is also incorporated into the design to allow for more control over exposure durations and promote the use of wider apertures. This allows for a more fluid rendering of moving subjects as well as greater control over your focus plane. A nine-blade aperture diaphragm benefits the ability to shoot with wider apertures by producing a more aesthetically pleasing out of focus image quality. Additionally, this lens is capable of focusing on subjects as close as 3.9" / 10cm for macro-like shooting.
A conventional bright frame viewfinder is used as the base construction for the Hybrid Viewfinder, and from which the LCD monitor was incorporated into. A viewfinder shutter can be opened or closed in order to use either the OVF or EVF, and with this method the highest clarity is attainable using both viewing methods. An approximate horizontal apparent field of view of 26° and 0.5x magnification offer comfortable viewing conditions that best suit the built-in 35mm wide-angle lens. High-refractive glass, a high-precision prism, and Super EBC coatings also contribute to producing a clear view for both the EVF and OVF.
While the optical viewfinder does give crisp natural viewing abilities, it is also aided by an LCD projection of customizable shooting information along the border of the frame. This information is useful in that it allows you to continuously use the OVF without having to check settings on the LCD or with the EVF setting.
The EVF provides you with 100% frame coverage by way of the 0.48" / 12.19mm 2,360k-dot LCD monitor. This monitor is able to provide a high resolution live view and is useful for confirming focus , exposure, depth of field, and white balance accuracy. The EVF can also be used for menu navigation and review of imagery.
An eye-sensor is located on the viewfinder to automatically turn off the rear 2.8" LCD monitor during eye-level viewing. These settings can further be adjusted to always keep the LCD off (and only use the viewfinder) or to always keep the viewfinder off (and only use the LCD).
The Hybrid Viewfinder also gives way to efficient and effective manual focusing performance. By using the phase-detection pixels located on the imaging sensor, Digital Split Image is able to assist in acquiring precise focus by showing comparative in and out of focus areas of the image. Also contributing to manual focus accuracy, focus peaking has been integrated and enables a more objective system of focusing by way of highlighting sharp edges and lines of contrast in a clear manner.
An efficient graphical user interface promotes greater intuitiveness for menu navigation and monitoring. The Q Button gives a one-touch solution to modifying commonly used camera settings quickly and easily. All of the menus and setting navigation is done on the rear 2.8" 460k-dot LCD that also provides high definition playback of still images and video. This monitor can be used to display an exposure histogram, an electronic horizon leveling gauge, and focus point zoom, too.
While recording video you can manually control the focus settings via the lens, and, additionally, you can control the audio level in four steps. A 3x digital zoom is available during movie shooting to effectively triple the lens' focal length to 105mm (35mm equivalent). White balance settings and Film Simulation modes can also be applied to movie recording to fine-tune the appearance of your videos.
