Sony has announced the A7S II, the latest iteration of its video-oriented, full-frame A7S camera series. The new model adds a range of pro-style movie functions including the ability to shoot 4K video internally with full pixel readout and no pixel binning. 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[v] movies which means that it collects information from approximately five times as many pixels that are required to generate Full HD[vi] and condenses the information to produce extremely high quality movies.
There's also an expanded ISO range from 50 to 409,600, a new in-body 5-axis image stabilisation system and the option to shoot Full HD video at a fast frame rate of 120 fps. The autofocus system on the A7S II has been upgraded and now offers 169 AF points and viewfinder magnification has been increased, up from 0.71 to 0.78x (roughly 38.5 degrees in diagonal field of view), to show clear images across the entire display area.
The new A7S II will be available in November 2015. Australian pricing has not been announced, though in North America the A7S II is expected to sell for around US$3000 body only.
