Before I got my E-PL5 I was a little worried that its control logic was slightly annoying. I primarily use aperture priority, and the default setup of pressing the exposure compensation button to unlock adjustments, and then having to adjust aperture with the arrow keys instead of the dial, seemed really counterintuitive. I read through the slightly horrible manual before buying and it looked like there might be the ability to change these around, so I took the plunge. Upon playing with the camera I changed a couple of settings, which you can find on p. 72-73. Dial function - I switched this so aperture is the default adjustment and exposure compensation is accessed by (shocker) pressing the exposure compensation button. Dial lock - I switched this to off. So if I want to adjust the aperture, I just spin the dial. This seems like how the camera should have been set up from the factory but hey now that I changed the settings around, all is well. The other setting I recommend changing as soon as you get the camera is to disable the Auto White Balance "keep warm color" option which is turned on by default and gives an ugly red/yellow cast under incandescent or CFL with incandescent-like color temperature. It's on p. 76 of the manual.
