Though the Shogun has not yet been released you can still obtain one of the best HD signals available on the market from the GH4’s HDMI port. This is 10bit 4:2:2 and oversampled internally from 4K, a bit like on the Sony FS700 but for only $1699. The video above shows how to setup the camera for recording 10bit 1080p onto the Atomos Blade.
In the next few days I should receive my Atomos Ninja Star which is a tiny low-profile recorder with no screen, for when you want to use the screen on the camera but benefit from the higher image quality of 10bit 4:2:2. Check EOSHD soon for a review.
