Sony has unveiled an updated version of its full-frame digital SLR camera Sony Aplha 7. Model ingeniously named A7 II. The camera has received 24.3-megapixel matrix with five-axis stabilized by shear matrix that can compensate for camera shake up to 4.5 CIPA standard stops. Also, the device is equipped with a system that synchronizes stabilization system in the housing with built-in stabilization of the E-series lens with optical image stabilization. Parameter ISO can vary from 100 to 25 600, and through image processing achieved Bionz X 117 pixels for detecting a phase 25 of measuring points and contrast. At the same time, the increased productivity enabled Sony engineers talk about a 30% increase in speed autofocus and a 50% improvement opportunities object tracking. The shutter can operate at speeds up to 1/8000 of a second, and in the mode serynoy speed shooting up to 5 frames per second. Video Unlimited 1080p at 60 k / s with the AVCHD codec and XAVC S.
