The Atomos Shogun is the perfect companion to the Panasonic GH4, which already shoots 4K internally on SDXC cards, however for those wanting to upgrade their footage to a 10bit 422 chroma sampling – the Atomos Shogun will provide such recording capabilities via HDMI. The Sony A7s with its full frame super-sensitive sensor can currently record 1080p internally, however the Shogun can unlock the true potential of this phenomenal camera giving it the 4K (UHD) treatment.
