That's brilliant - I've been trying to work that one out by combinations of buttons for months!
How does that compare to Flex Point Focus??
Basically I am the same - I want it to focus in the middle.
However - I would prefer the Exposure to average the whole image (think I can do that one - 256 segment) Got confused as the exposure uses the word Flex Point as well. So I think I have been trying to set the focus in the centre and setting the exposure in the centre instead.
Thanks for the helpfull pointer.
