Sony α7S II full-frame mirrorless 4K camera with 5-axis optical image stabilisation

Posted by Charbax – September 16, 2015

Sony releases the new Sony Alpha 7S Mark2 for ultra-high sensitive, wide dynamic range, 5-axis image stabilisation, 4K video with full pixel readout and no pixel binning in full-frame format. The Sony α7S II delivers a sensitivity range of ISO 50-409600 using its 35mm full-frame 12.2 megapixel image sensor and the Sony BIONZ X image processing engine, optimising the dynamic range across the entire ISO range and broadens the range of tonal gradation in bright environments and minimises noise in dark scenes. The Sony α7S II can record 4K movies internally in the XAVC S format where 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 FHD video. The Sony α7S II can record 120fps at 100Mbps with full pixel readout without pixel binning in full frame format which can be edited into 4x/5x slow motion footage in Full HD. The new Sony α7S II offers 5-axis image stabilisation that 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. The autofocus system on the Sony α7S II offers 169 AF points for fast, precise focusing with greater accuracy. The power of the image sensor means that the absence of noise in images generated, 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 with the naked eye. When shooting video, the AF performance is twice as fast as the predecessor model. The XGA OLED Tru-Finder in the α7S II has been upgraded and offers the world’s highest viewfinder magnification 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 and 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. The Sony α7S II also has Wi-Fi and NFC to work with Sony’s PlayMemories Mobile application available for Android and iOS. The Sony α7S II full-frame interchangeable lens digital camera will be available in Europe in November 2015, priced at approximately €3400.
