We've greatly benefitted from the Open-Source community, especially with APM/Pixhawk and Mission Planner. Part of keeping this community together and advancing is to share our experiences and solutions. To be honest, I haven't had much time to do this but I'm doing my best to help. Today, I'd like to share with you our solution to triggering a camera via a wired remote shutter release cable WITHOUT needing third party hardware. I hope this little guide is useful to some of you!
A special thanks to all the developers involved with Ardupilot and Mission Planner.

@Bill and @Asim, so the suggestion @Oliver made doesn't work?
I have been using the same home made cable for over a year on a A6000, QX1 and Nex 3N. The voltage on the sony cameras is 3.3 volts which is the same as a Pixhawk so you don't need a logic level converter. I checked and the current to trigger is very low much lower than the 40mah max of the Pixhawk. I have taken thousands of pictures and have had no problems.
Oliver, thanks for sharing as I never got around to creating a guide.
I got a Sony Nex5 camera I assume the same trigger cable can be apply to it. I will try it soon. Thanks Oliver Volkmann
