Hi guys! Thank you for your wellcome. I hope to keep contributing to this great project.
Rough-tuning the PID controller is quite easy. First, increase the value of Kp (in steps of 5 units) until setpoint is overshooted. Then, come back to the previous value. Now we must have a stable control, but setpoint is not reached. Then increase the Ki value in steps of 0,05 until setpoint is reached. By now, I don't see as neccesary to use the derivative term.

I think that you can safely use a value of 40 to start tuning the Kp. When Kp is tuned, a starting 0,2 value for Ki can be used. Of course, these values can be too much for your camera, use with caution and at your own risk ;-)
