Thanks for your responses! I'm using single point AF with face detection turned off. Often when I aim the camera, the focus point will jump to a particular area of the frame, for example in the lower left quadrant of the frame. I want it to stay still (I have it set to the center of the frame,) allowing me to move it or leave it where it is. I can't get the darn thing (the focus area) to reliably remain stationary.
Ideas? And thanks.
