Sony Alpha A7SII Body

Sensitivity Mastered

The α7S II delivers an awe-inspiring sensitivity range of ISO 50-409600 , thanks to the combination of its 35mm full-frame 12.2 megapixel image sensor and BIONZ X image processing engine. The sensor optimises the dynamic range across the entire ISO range and broadens the range of tonal gradation in bright environments and minimises noise in dark scenes meaning that it delivers impressive results even in the most extreme conditions. The upgraded image processing algorithm of BIONZ X maximises the sensor’s capabilities and improves depiction throughout the full sensitivity range with particular emphasis on the mid-to-high range. This means that the resulting stills and movies demonstrate extra-fine detail with minimal noise.

Video Master

The impressive video credentials of Sony’s new α7S II camera include the ability to record movies in 4K quality3 internally through use of the advanced XAVC S codec4, which can record at a high bit rate of up to 100 Mbps.  Because information from all pixels is utilized without line skipping or pixel binning, the camera can maximize the expanded power of the full-frame image sensor and produce 4K movies with higher image clarity and negligible moiré.

This full pixel readout without pixel binning is also employed when shooting Full HD video (24p/30p), where the camera collects information from approximately five times as many pixels that are required to generate Full HD 1920×1080 and oversamples the information, producing movies of extremely high quality and detail.

Also, in a first for the α7 series, the α7S II can record Full HD at120fps at 100Mbps5 in full frame format, which can be immediately reviewed on the camera screen and eventually edited into appealing 4x/5x slow motion footage in Full HD (24p/30p) resolution.

Video functionality has been further enhanced with new picture profile settings; S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3, delivering wide dynamic range and simple color correction.  The α7S II even offers impressive 14-stop latitude in the S-Log3 gamma setting, while also supporting other popular profiles for cinematographers including S-Gamut/S-Log2.

Other enhancements include the addition of Gamma Display Assist, a new function that allows users to monitor images or check focus when recording S-Log movies, and the improvement of the Zebra function for even greater control.

5-Axis Image Stabilization

The new α7S II is equipped with the innovative, highly acclaimed 5-axis image stabilization system from the α7 II and α7R II cameras. The system corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) which has the greatest impact on image quality and tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects night shooting and/or video recording.

Autofocus Accuracy

The autofocus system on the α7S II has been upgraded and now offers 169 AF points for fast, precise focusing with greater accuracy compared to the original model.  The low noise image produced by the image sensor of the new camera enables the Fast Intelligent AF to detect contrast more easily and react speedily even in low-light situations (as low as EV-4), when it’s even tough to check focus with the naked eye.  The AF performance is also twice as fast as the predecessor model during video shooting.

Electronic Viewfinder

The XGA OLED Tru-Finder in the α7S II has been upgraded and offers the world’s highest viewfinder magnification7 of 0.78x (roughly 38.5 degrees in diagonal field of view) and shows clear images across the entire display area.  The use of ZEISS T* Coating ensures sharp reduction of reflections on the viewfinder.  Unlike an optical viewfinder, the OLED Tru-Finder can be used to instantly show how exposure compensation, white balance and other selected settings are affecting the displayed image.

User Upgrades

A number of enhancements have been made to the look and feel of the α7S II to make it more user friendly, reliable and intuitive.  Its magnesium-alloy body is both α7S II_rear (3)light and highly robust and the grip and shutter buttons have been re-designed so that the camera feels more natural in the hand.   Additionally, silent shooting mode can be activated at up to 5 fps continuous shooting8 and there is reduced-vibration shutter movement9.

The lens mount has been further reinforced to ensure greater rigidity, particularly when attaching third party lenses and users can now charge the camera via a USB power supply while the camera is in operation, thus extending battery life.  The α7S II is also Wi-Fi® and NFC compatible and fully functional with Sony’s PlayMemories Mobile application available for Android™ and iOS™ platforms, as well as Sony’s growing range of PlayMemories Camera Apps, which add a range of fun creative capabilities to the camera.
