Sony QX10 mod for remote wire shutter trigger
The Sony QX10 is a nice lightweight 18 MegaPix camera for very little money (costs less than 100$ online, shipping included). It looks like a good one for aerial mapping missions. Unfortunately, it does not support USB cable remote triggering (unlike the much more expensive models in the QX family). Also, a smartphone app allows to trigger the camera via Wifi but that does not allow a direct shutter trigger control via Pixhawk, which was the purpose for getting this camera.
