Buy your a7sII at = http://amzn.to/2r46zDK
I go through my custom menu settings on the Sony A7sII after one week of use. With this setup I can quickly change AF, ISO, IBIS focal length, AF/MF, MF zoom, start and stop video clips, F-stop, and all the settings I need to access for portraits and video use.
This video was shot with my Panasonic FZ1000 with the Giant Squid mic plugged direct into the 3.5mm mic input jack.
