The clarity of the signal achieved by the optimization of every aspect of its processing circuitry. The enhanced image quality produced by the powerful EXR Processor II.

The advanced APS-C X-Trans CMOS II sensor features embedded phase detection pixels and an optimized AD converter for faster signal readout and accelerated operations, while the new EXR Processor II more than doubles processing performance compared with the previous generation processor(*1). From the world's fastest AF of 0.08 sec.(*2) to a near-instant start up, the X100S's response times are an absolute delight.

Depending on the subject and scene, you have the power to instantly switch between two viewfinder views: optical or electronic. The visionary Hybrid Viewfinder that reinvented the essential pleasure of looking through the eyepiece and capturing each moment, has evolved with new levels of enhanced performance.

The superb performance of the bright lens is cleverly integrated into the slim compact body, ensuring it is perfectly pocketable. The versatile focal length of 35mm (35mm format equivalent) delivers an angle of view ideal for a diverse range of subjects, scenes and whatever captures the photographer's eye.

Advanced technology transfers the power of the lens into true-to-life photos.

X-Trans CMOS II incorporates an original color filter array with a highly random pattern, eliminating the need for an optical low-pass filter (OLPF). These filters are used in conventional systems to inhibit moiré at the expense of resolution. The X-Trans CMOS II array lets the sensor capture unfiltered light from the lens, achieving an unprecedented level of resolution.
In addition, utilizing the enhanced performance of the EXR Processor II, Lens Modulation Optimizer (LMO) factors are calculated to compensate for aberrations and diffraction blur that occur when light passes through the lens and then are applied to produce images with amazing sharpness.

Setting new standards in low noise performance
X-Trans CMOS II & EXR Processor II
In the X-Trans CMOS II sensor, the optimized circuits elevate the S/N ratio and produce a clean signal that is enhanced by the powerful new EXR Processor II for a further increase in image quality. The original signal processing of the X-Trans array featuring advanced noise separation technology combines with a newly developed noise reduction process that exploits the color differential to suppress chromatic blur, resulting in image quality far beyond its sensor size.

Auto-switching between phase detection and contrast AF. New Intelligent Hybrid AF brings your scene into focus in only 0.08 sec. (*3)

Equipped with both the super fast phase detection AF system, and contrast AF for accurate focusing in dark scenes, Intelligent Hybrid AF instantly switches to the optimal focusing system. Applying the fastest algorithm depending on the subject and scene, Intelligent Hybrid AF can bring your subject into focus in the blink of an eye - only 0.08 sec(*3). at its fastest speed so those priceless moments will never escape your lens.

EXR Processor II
Double the processing speed of the previous generation.

The image processing power of the newly developed EXR Processor II not only produces images with increased resolution and higher quality at higher speeds, but also accelerates operational responses. Adoption of a dual CPU and increased clock frequency elevate performance to about twice the processing speed of the previous generation processor(*4). These improvements also speed up operation, reducing cold start-up time to only approx. 0.5 sec.(*5) Working in tandem with the high-speed signal readout of the X-Trans CMOS II sensor, the processor reduces the shooting interval to 0.5 sec. and raises the maximum High-Speed Continuous Shooting Speed of 6.0fps (max. 29 frames).

Optical Viewfinder (OVF) or Electronic Viewfinder (EVF). With the X100S, you have the choice.

Optical Viewfinder (OVF)

Electronic Viewfinder (EVF)

Optical Viewfinder (OVF)

Select the Optical Viewfinder when you want to see the subject in the same bright clarity that you see with the naked eye, or when time lag is an issue. Framing shots with the sharp edge-to-edge definition of the bright frame is a joy. In addition, the freedom to customize the information displayed in the viewfinder lets you confirm key settings.

Electronic Viewfinder (EVF)

Select the EVF to visually check focus, exposure, white balance and depth of field while you compose your shot. You can also take advantage of the “Live View” in the EVF when you require precision framing for macro shots.

Optical design with a priority on performance

Optical design with a priority on performance The simple all-glass lens configuration (6 groups/8 elements) is designed around a single high-performance double-sided aspheric lens. Uncompromising image quality is assured by the application of multi-layer HTC-EBC(High Transmittance Electoron Beam Coating) coating and other technologies. The result is perfectly balanced optical excellence promising low aberrations, sharp resolution and faithful color reproduction.

Capture superb “bokeh” effects with the 9-blade aperture diaphragm.

Providing a circular opening at the largest aperture, the 9-blade aperture diaphragm lets you capture perfectly defocused background effects. Even with a slightly wide angle, the background is softly out of focus while the foreground is sharply defined.

Get closer with 10cm Macro Photography

The X100S lets you bring the edge of the lens as close as 10cm from your subject. Outstanding shooting range and exceptional performance in a variety of scenes set this lens apart.

“Digital Split Image”, the world's first manual focus system to exploit the power of phase detection pixels.

Tapping the power of the phase detection pixels integrated in the X-Trans CMOS II sensor, Digital Split Image helps you manually focus your shot with greater precision. While checking the split image displayed in the LCD monitor or EVF, you can manually adjust for pinpoint focus, especially helpful when working with an open aperture or macro shooting.
