I have been flying my p3p now for about 50 flights and have yet to figure out how to get the exposure to maintain an ev of 0. Why do I always have to constantly fumble with the shutter speed knob to maintain the ev at 0 manually. I know I'm doing something wrong but for the life of me I can't figure it out. Is there any way to set the exposure to automatic so when I'm flying I don't have to manually change the shutter speed? I have tried pressing the ev lock but it doesn't seem to do anything.....
