With my RX1 coming I was thinking, what settings make the most sense for you? I know from reading that the functions that can be set/assigned are very flexible so there is a lot of latitude but some make more sense than others. So far I've deduced that for me, flexible spot focus is my preference for what I like to shoot a lot (people with critical focus on the eyes)...but that's all I've decided on so far. On my previous cameras I tended to change ISO a lot but the auto here seems very good so that's probably not something that I'd set. I'm sure I won't be quickly toggling between "effects" and things like that. What settings did you settle on that made sense to assign to a function button that you need/like to switch easily?
