White Balance (WB) vs. Exposure Settings on Outside
Okay, one thing I should mention is that I think that the exposure settings should be on the outside, on the joystick button, like the flash and white balance settings are. Actually, since it is more likely that you would change your exposure more often than your WB (for instance, if you are outside on an overcast day, how many times will the WB have to be changed?), then it would make sense, IMO, to swap out the WB setting on the joystick for the exposure setting.
For the past several times I have shot on overcast days, I have needed to change my exposure settings more than my WB, due to the differences of available light in the various settings when I was in outside.
So I just think that they could have thought about this more deeply. It would be great to know if this could be an option for a firmware update.
