Leading the way to the ultimate image quality, the X100s features the new APS-C 16M X-Trans CMOS II Sensor & EXR Processor II. 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.
Also the unique integration of phase detection pixels in the array contributes to the dramatic leap in AF speed. Fujinon 23mm F2 fixed focal length lens, quality without compromise was the goal when the FUJIFILM X100S was being developed. While featuring the generous brightness of a maximum F2 aperture, the large-diameter rear lens group is integrated into the body for an ultra-slim profile.
In addition, the optimization of the sensor for this special lens fully exploits the advantage of a fixed focal length lens for superior edge-to-edge image quality. The new Hybrid Viewfinder offers expanded freedom in a range of challenging shooting conditions. When you want to view the subject with maximum clarity or keep shutter time lag to a minimum, the Optical Viewfinder (OVF) impresses with stunning optical quality. For confirmation of focus, exposure, white balance and depth of field while shooting the scene, just move the lever to Electronic Viewfinder (EVF) featuring an integrated 2,360K LCD.
Using 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 viewing 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. Focus Peak Highlight For pinpoint manual focusing highlights high contrast areas of your subject for smoother and more accurate focusing.
