A new Firmware update is available for the killer Atomos Shogun, which is a device that can take advantage of the clean HDMI output that the most of the newer Sony cameras offer. It can then store and convert the video data to your preferred high quality format of choice. It's not exactly cheap @ ~$2000 US @ BHPhoto, but the alternative is a much more expensive camera body for sure! You can get the update here: http://www.atomos.com/support/

Check out this killer video rig that I just posted a little while ago using the Sony A7s and Atomos Shugun as well as all the other goodies needed >>

Thanks to SonyAlphaRumors for the heads up on this...

Enhancements and Fixes:
* Fixed occasional 1/2 blue frame chroma swap (Yr Yb) when recording 4K 30p on A7s and GH4.
* Implemented user feature request. WFM to automatically minimise from full screen or bottom 3rd to mini in order to monitor the display.
Delayed Features:
* Playback – Unfortunately we have experienced some difficult issues, which are being solved now. We now estimate end of January for this release. It could be sooner if solving these problems goes well. We apologise once again for these delays and appreciate your patience.
* DNxHD – We expect Avid DNxHD to be available mid February
* 3D LUT’s – Expected March
* Cinema DNG – Due to the delays in releasing playback and DNxHD, Cinema DNG will also be delayed until March. However we can let you know that the following are planned to be implemented for RAW support: FS-RAW (FS700, FS7), C500, Arri RAW, Panasonic V-RAW
Known Issues (Atomos):
* Rolling timecode trigger does not work at 1080p50/60.
* RED & C500 SDI 1080p50/60 bug found.
Known Issues (3rd party):
* Transcend media only works if inserted with unit already turned on
* OCZ media not recommended
* BMD 6G-SDI products not compatible in UHD4Kp30. Shogun is compliant with the current SMPTE 6G-SDI standard, the HyperDeck Studio tested was not compliant. Until BMD update to the current SMPTE provisional 6G standard ST 2081-1:201x (Version 4, 2014-06-04) on their 6G products, Shogun will not work with these devices.
Anybody using one of these yet?
