I recently bought a new camera, a Panasonic FZ1000, and noticed on more than one occasion when I was photographing my wife in a posed situation, and I choose to zoom in a little for the shot, the camera struggles to focus on her face (AF).
Is this because the elements around her in the shot, (darker, more defined lines) have significantly more contrast to them than her face, which is of course normal skin toned? Trying several times to refocus (AF) did not work brilliantly, although it eventually achieved a reasonable result.
I have become confused reading my manual and various discussions on this. It all seems to get very complicated. Can anyone give me straightforward advice, i.e., techniques to improve focus in this specific type of situation, please?
