The Sony Alpha a7S Mirrorless Digital Camera features a full-frame 12.2MP Exmor CMOS sensor and BIONZ X image processor to enable notable video and still image quality with an expansive dynamic range, low noise, and extended sensitivity to ISO 409600. At the sensor level, this full-frame sensor features a unique on-chip gapless lens design, which incorporates small lenses between neighboring pixels in order to increase light-gathering efficiency and promote greater image quality across the entirety of the sensor plane. The sensor and processor combination also avails a wealth of speed throughout the camera system, including a top continuous shooting rate of 5 fps, support for 4K video recording, and a fast 25-point contrast-detection AF system with sensitivity to -4 EV.
The Sony FE 28-70mm f/3.5-5.6 OSS Lens is a versatile, compact, and lightweight wide-angle to portrait-length zoom lens designed specifically for full-frame E-mount cameras. It is also compatible with APS-C-sized image sensors and will provide a 35mm-equivalent focal length range of 42-105mm. In regard to the optical design, three aspherical elements and one extra-low dispersion element help to reduce aberrations and distortions while contributing to notable image sharpness and clarity.
