For those who have handled both cameras, can you describe the customization differences? I'll assume that the EP3 has more buttons and dials, therefore, more ways to customize the camera settings. However, with the EPL3, do you wish you could customize the settings more? Also, for the buttons (and directional pad presses) that Oly allows you to customize, can you assign any function to the customizable button (or directional pad press)? Or does Oly restrict you on functions that you can assign? The restrictions have always been one of my pet peeves about customization settings for a lot of difference cameras. For example, I wish I could assign ISO to one of the upper customizable buttons on my GH2. But I'm stuck with ISO as assigned by Pany to one of the lower non-customizable buttons. Thanks!
