Nikon D5600 / Nikon 25-140 lens
I have noticed sometime when I press the button half way the auto focus does not work. I have to push it a few times and then it will work correct. I thought maybe it was just me, then last weekend I was going to take a picture of my granddaughter by a helicopter and she was scared so the pilot said he would take one of both of us. He mentioned the auto focus seemed to not be working, the he said it was.
The battery was low, not sure if it has ben low the other times but will be paying attention to it now. I know when the battery gets to a certain point it will not let you take pictures, it locks the shutter but you can still access the camera.
Could this be the battery?
