My E-M1 Mark II is mounted on a tripod and I have a remote trigger cable attached. I have it aimed at my hummingbird feeder. My lens is the 12-100 f4. The camera is in manual focus and doesn't move. However, if I walk away from it for a while it is out of focus when I return and I often miss my shot. Can someone explain why I lose my focus and how to avoid this. Thank you.
