image processor and is compatible with A-mount lenses. GPS has been dropped in favour of Wi-Fi and NFC. The focus area is wider and denser, with a class-leading 79 AF points including 15 crossing sensor combined with subject tracking and eye-focus capabilities. The SLT design avoids the need to flip the mirror out of the way with every shot, allowing a rapid 12 fps burst speed for up to 60 frames in full resolution. Unlike most DSLR cameras, the phase-detect focus unit is operational during live-view and video (which is Full HD at 60p/50p and 24p/25p). The resolution of the camera is 24 megapixels. Sony's A-mount cameras feature in-body image stabilisation and the α77 II is the first of such to also stabilise the viewfinder when taking still images. ISO ranges from 50 to 25600.
