A first look at the Sony Alpha 7S 12MP full-frame with 4K output
Unveiled: The Sony Alpha 7S
The Sony Alpha 7S is the first full-frame camera able to read out its entire sensor fast enough to output 4K 30p footage from its entire sensor. Or, at least, the full width of its sensor: it only outputs the 16:9 region of its 3:2 36x24mm sensor. Importantly, though: no pixel binning or line skipping are employed.
