Focus points for E5
I have been using the E5 for a year now and am still learning all its abilities. I love the camera and its uses and have some super pics from it. Had the E510 before. I have been studying all the functions and have a question for users of the E5.
When you are working with setting the focus points there are 3 modes indicated at the bottom of the screen-----an all points (11 position) focus, a single middle dot focus point and a third which looks like a plus sign focus.
I have worked with the first two well, but the plus will never light up on my camera and has never lit during my experience with it. Am I doing something incorrectly (or maybe do not know how to use it) or could it be a fault with the camera? I can work the other 2 focus areas fine and they light up when indicated.
I have David Busch's book on the E5 but can not find anything about this in it or in researching.
Thank you for you help in advance.
