Making strides in the video arena, the a7S II Mirrorless Digital Camera from Sony offers an impressive blend of sensitivity, dynamic range, resolution, and speed to benefit a versatile multimedia workflow. Revolving around a full-frame 12.2MP Exmor CMOS sensor, the a7S II is capable of internal UHD 4K recording at 30 fps with full pixel readout as well as 1080p recording at up to 120 fps, all in the XAVC S format. For both stills and video recording, the BIONZ X image processor also pairs with the sensor to enable expanded sensitivity to ISO 409600, continuous shooting to 5 fps, and fast intelligent autofocus with low-light sensitivity to -4 EV. Further enabling working in difficult lighting conditions, 5-axis SteadyShot INSIDE image stabilization compensates for vertical, horizontal, pitch, yaw, and roll camera movements for sharper, smoother handheld recording. Complementing the 4K recording capabilities is a redeveloped recording setup, including the ability to utilize S-Log3 Gamma and S-Gamut3 in addition to S-Log2, for increasing dynamic range values by up to 1300% to better match high-end post-production workflows. For clearer monitoring potential, an enhanced Zebra function better supports working with S-Log gamma settings and a Gamma Display Assist helps to preview imagery with natural contrast by converting S-Log2 and S-Log3 settings to the ITU709 gamma for easier on-camera viewing. The a7S II is also characterized by a compact, yet robust, magnesium alloy body design that incorporates a high 0.78x-magnificatio n Tru-Finder OLED electronic viewfinder. With a resolution of 2.36-million dots and a Zeiss T* anti-reflective coating, this finder benefits working in a variety of lighting conditions and is capable of previewing exposure and settings adjustments prior to recording. A rear 3.0inch 1,228,800-dot LCD screen is also available, and features a tilting design to support working from high and low angles. Additionally, built-in Wi-Fi connectivity with NFC allows you to pair mobile devices to the camera for wireless sharing and remote camera control. Full-Frame Exmor Sensor and BIONZ X Image Processor A 12.2MP full-frame Exmor CMOS sensor and BIONZ X image processor work together to enable an expansive dynamic range with minimal noise and notable sensitivity from ISO 100-102400, which is further expandable to ISO 50-409600. Coupled with the large individual pixel size the 12.2MP sensor affords, this camera is well-suited to use in low-light conditions. The sensor's design also features a new-generation RGB color filter array, as well as a gapless on-chip lens design. Together, these two technologies enable truly efficient light-gathering abilities that further reinforce the low noise, high-sensitivity design. Furthermore, an anti-reflective coating has also been applied to the seal glass of the image sensor to minimize surface reflections, glare, and ghosting for contrast-rich, color-neutral imagery. The sensor and processor combination also avail a wealth of performance- related benefits to still shooting, including a Speed Priority continuous shooting rate of 5 fps, or a 2.5 fps shooting rate with continuous AF. The Fast Intelligent AF system employs 169 AF points, which is comprised of 25 contrast- detection points and nine central AF points that have been split into 16 segments each, in order to provide both speed and accuracy in low-light conditions down to -4 EV. Internal UHD 4K Recording and Full Pixel Readout Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and, based on the 12.2MP resolution, full pixel readout is possible that is void of pixel binning for higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow
