IBC 2015: The Brand New Sony A7S Mark II Provides 4K Internal Recording and 5-Axis Image Stabilization

It seems that Sony is going to dominate IBC again. Out of nowhere, the company announced the brand new and long-awaited Sony A7S II mirrorless compact camera. It provides the highly-demanded 4K internal UHD 4K recording at 30 fps with full pixel readout as well as 1080p recording at up to 120 fps, all in the XAVC S format  along with the relatively new 5-axis in-camera stabilization.

The new S-Gamut3.Cine/S-Log-3 and S-Gamut3/S-Log3 profiles are also available on the camera enabling up to a 1300% wider dynamic range for smoother tonal and color gradations, along with enhanced sensitivity and clarity in shadows and mid-tones. These profiles also lend themselves to greater compatibility within a professional workflow and are well-paired to the Cineon Log gamma curve for versatile post-production grading and color control.

Here are a bunch of promotional videos of the A7S Mark II provided by Sony.

    I wander how long can it internally record 4K before overheating?
