Upon initially poweing up the P4P and testing the focus in manual mode in a controlled enviroment with a back focus chart at about 50 feet away, focus is about 2-3 lines from infinity. After having the P4P powered up for 30 minutes to maintain focus the infinity slider is 1 line to or all the way to infinity to have focus. If I cycle the power on the craft the slider goes back to 2-3 lines from infinity to be in focus. How are we going to focus this in low light conditions in manual mode if the focus point to infinity keeps changing and not consistant?
Cheers

This happens for me as well. I have not tried waiting 30 minutes, but infinity is definitely on line 7 or 8 in manual mode. 9 is ??? slightly out of focus.
