The Fuji X100s is the update to the very popular Fuji X100. Key features include:

Improved Sensor. The X100s features a second-generation 16MP X-Trans APS-C (crop) sensor, allowing the removal of the optical low-pass filter. It still features a fixed 23mm f/2.0 lens, providing a 35mm focal length equivalent after sensor-crop factor.

Improved Autofocus Performance. While the X100 suffered from lagging autofocus, the X100s has Fuji’s Intelligent Hybrid Autofocus system that uses both contrast- and phase-detection methods for much faster performance.

Improved Resolution, EVF, and ISO. The X100s still uses a 460k-dot, high-resolution LCD like the X100, but has a much improved 2,360k-dot electronic viewfinder. The camera captures images in both RAW and JPG formats, but it offers even better native ISO performance than its predecessor, with an ISO range between 200-6,400 (expandable to 100-25,600). The camera’s video features also see substantial improvement, with Full HD capture at up to 1,920 × 1080 at 60 fps with a 36 Mbps bit-rate.

Improved Optical Design. The improved 23mm f/2 lens has a six group/eight element design with one double-sided aspherical element to reduce aberrations and improve sharpness, while its Super EBC coatings reduce lens flare and ghosting. It still has the X100’s nine-blade aperture diaphragm and its built-in three-stop neutral-density filter.

Improved Controls. The control layout on the back of the camera is also improved, with a few buttons gaining new functions for improved ergonomics while shooting.
