I'm trying to set up for a focus stack session. I autofocus focus on the nearest point and click the left lock icon. When I try to auto focus on the farthest point it tells me that autofocus is locked and cannot complete the task. I unlock the left icon, auto focus the farthest, then lock the right one, but then nothing seems to want to stack.
I'm sure I'm missing something fundamental here. I am a newbie. Any help would be greatly appreciated.
