The pesky little video button on the NEX-7 is taken care of!

I used a tiny washer (careful application of epoxy- avoid superglue!) to cover the outside of the video button so that accidental touchings will not trigger the video. A tiny press/snap button is tacked onto an end of the strap that is needed to push on the video to activate/deactivate it (a pen or pencil also would do but having this in close proximity all the time is handy).
Also in the picture is the Gariz case plus a trimmed off plastic flash holder complete with a Novoflex miniconnect coupling. The height of the camera now is ~85mm. Perfect for my handling.
