The e520 has 3 focussing points available in normal view. I assume this is the same for the other e4xx and e5xx models. If, for instance, you have composed your image and you have an object/person covering each AF dot and these objects/people are all different distances away, how does the camera choose what to focus on? Am I correct in assuming that in Auto, A, and S modes it will try to alter the depth of field to get everything in focus. Is that correct or does the centre spot (if selected) get priority? I'm historically a centre spot focus on half shutter depress and re-compose merchant but when using a tripod this is not so easy. I appreciate you can use focus lock and recompose on a tripod but I would like to understand the logic behind the AF Area.
