Perhaps it'll happen for us in 3.00

the sensor stabilization is the selling point for me! The GH4 still have better battery life and 4:3 aspect ratio over the A7sII but I can live with the battery especially because you can use a dummy battery/charge through USB port.
I'm sure a firmware update will bring 4:3 to this camera

People....you cannot complain about the way this looks when you know that their key light was 238,900 miles away

I've used Dropbox because of how simple it is. Drawback are that you have less space than sites like Google Drive so I've had as many people as I can sign up to get me more space.
Of course if you pay for storage then you aren't limited

Worth the upgrade if you use a GoPro often but I think I'll wait until the 5 or 6 so the battery life improves and they reach Full 4K.
