About
An interview from the 2015 PhotoPlus Expo in New York City with Kenta Honjo of Sony Electronics. Sony Electronics is a leading manufacturer of audio, video, game, communications, key device and information technology products for the consumer and professional markets. In this interview Kenta talks with us about the newly announced Sony Alpha a7S II Mirrorless Digital Camera.
The a7S II can record 4K movies internally in the XAVC S format meaning that content is wonderfully detailed. Because information from all pixels is utilised without line skipping or pixel binning, the camera can maximise the expanded power of the full-frame image sensor and produce 4K movies with higher image clarity and negligible moiré. Full pixel readout without pixel binning is also employed when shooting Full HD movies which means that it collects information from approximately five times as many pixels that are required to generate Full HD and condenses the information to produce extremely high quality movies.
In a first for the a7 series, the a7S II can record 120fps at 100Mbps with full pixel readout without pixel binning in full frame format which can be edited into wonderful 4x/5x slow motion footage in Full HD. The a7S II also has the ability to shoot 4x/5x slow motion footage internally which can be immediately reviewed on the camera screen.
The a7S 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 functionality has been further enhanced with new profiles; S- Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3. These new profiles deliver wide dynamic range and colour correction is easier to perform. The a7S ll even offers impressive 14-stop latitude in the S-Log3 gamma setting. The camera also supports S-Gamut/S-Log2 which is very popular among cinematographers and videographers. GammaDisplay Assist is a new function that allows users to monitor images or check focus when recording S-Log movies and the Zebra function has been improved for even greater control.
The new a7S II is equipped with the innovative 5-axis image stabilisation system that is proving extremely popular in the a7 II and a7R 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 or video recording.
