The World’s fastest Auto Focus and High-speed EXR Processing

The X100S offers the world’s fastest AF speed of just 0.08 seconds plus a variety of manual focus assist modes

Intelligent Hybrid Auto Focus (AF)

Auto-switching between phase detection and contrast AF, new Intelligent Hybrid AF brings your scene into focus in only 0.08 sec*.

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 just 0.08 sec*.

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**. These improvements also speed up operation, reducing start-up time to approx. 0.5 sec***. 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 continuous shooting speed to 6fps.

High-speed continuous shooting

Maximum high-speed continuous shooting speed of 6fps (max. 29 frames). Shoot at a maximum burst speed of 6 fps at full 16 megapixel resolution to capture a series of exposures of moving subjects and other challenging photographic scenes.

High Performance mode

From instantaneous auto focusing in as little as 0.08 sec*, to faster start-up; you can take the performance of the X100S to its limits. Also after turning OFF the power, the X100S enters a "sleep" mode (for a maximum of 24 minutes). Turn ON the power during this time, and the X100S "wakes up" instantly, reducing the normal start-up time from about 0.9 sec, to approx. 0.5 sec, ready for you to frame and capture the moment.

Focus mode selector

The focus mode selector on the side of the camera lets your fingers smoothly find and switch between AF-S (Single AF), AF-C (Continuous AF) and MF (Manual) while looking through the viewfinder.

Selectable AF with a 49-point metering matrix

Within the 49-point matrix of the autofocus area on the screen, AF accurately recognises the primary subject and brings it into crystal clear focus. It also lets you freely select the position of the AF frame. Using the LCD monitor, you also can change the AF frame size for pinpoint focusing.

0.01-sec. shutter lag

The shutter time lag is only 0.01 sec., so you can capture the precise instant you wish to.

AF assist lamp for low-light scenes

In low light settings when even the subject is hard to see through the viewfinder, the AF Assist Lamp illuminates the subject and assists Auto Focus.

Manual focus assist modes

Digital Split Image

Making use of the built-in phase detection pixels, the X100S is the world’s first** camera to offer a Digital Split Image feature to help 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 a wide aperture or shooting focus-critical macro images.

Focus Peak Highlight

When manually adjusting focus, this function emphasises the outline of the subject focus plane allowing smoother and more accurate focusing.

Fast and accurate manual focussing

In the viewfinder, the distance index bar is displayed together with the depth of field scale and aperture value, providing helpful guides for focusing. For pinpoint precision in manual focus mode, just press the Command Dial and confirm sharpness with a 5x zoom view of the focus point. And at a touch of the AE/AF Lock button, you activate the built-in Focus Aid function for automatic focusing of the subject in the focus frame.
