The α7S II has evolved in both Stills and Movies adding internal 4K video recording (1), uncompressed 14-bit RAW, 5-axis image stabilization, High-speed AF while maintaining its legendary low-light capability.
The innovative α7S II features a 12.2 effective megapixel full-frame Exmor CMOS sensor paired with a powerful BIONZ X image processor, allowing it to shoot at a sensitivity range of ISO 50 – 4096004(2) with unprecedented dynamic range. The extra-large pixels on the α7S II collects dramatically more light than traditional cameras to produce beautifully detailed low-noise images in even the most challenging lighting situations.
The α7S II is the world’s first5 camera to offer internal 4K movie recording1 in the full-frame format with full pixel readout and no line skipping or pixel binning - resulting in images that exhibit higher resolution and less moiré and jaggies than typical 4K movies. It also provides you the option of shooting 4k in the super 35mm format and the ability to capture uncompressed 4:2:2 Full HD or 4K QFHD output via HDMI to optional 3rd party external recorders6. Enjoy the improved autofocus with 169 AF points and let every lens benefit from the 5-axis SteadyShot INSIDE image stabilization.
The α7S II has been upgraded from the α7S and now offers 169 AF points for fast, precise focusing with greater accuracy compared to the original α7S. The low signal-to-noise ratio produced by the image sensor of the α7S II 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 on the α7S II is also twice as fast as the α7S during video shooting.
The 5-axis SteadyShot inside image stabilization system is fine-tuned for 4k video capture. It accurately compensates for blur caused by camera shake from five different directions—vertical, horizontal, pitch, yaw and roll—as opposed to only two in previous systems. The 5-axis image stabilizing system excels during video recording and even compensates for blur caused by the user walking or running. It’s a true marvel of engineering. You can even monitor the stabilizing effects of camera shake compensation in the viewfinder or LCD screen while shooting still images by pressing the shutter button halfway or magnifying the image, and while shooting movies by entering movie mode.
