We've been delivering the Atomos Shogun to professional cameramen and entusiasts alike for the past few months in droves, as it has proven quite popular month the GH4A7s crowed and FS700 and FS7 users as of lately. The Shogun is really 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. The Australian gear maker recently announced their firmware update schedule for the Shogun and today AtomOS 6.21 firmware is available to download. The company advises Shogun owners to update to 6.21 firmware immediately as it fixes some bugs that were found in 6.2. See details below. Atomos Shogun 6.21 Firmware Update Release Notes
