Well, it's a mystery to me at least! To my eye, the recently introduced simulated OVF feature in the E-M5 mkII does a remarkably good job of matching the white balance of the image displayed in the EVF to the colours of the scene as I perceive them naturally, which of course is how one would expect a real OVF to behave. Naively, I'd have thought that there are many situations in which it would be really useful to be able to apply the S-OVF white balance to the actual exposed image, not just the EVF display. It seems like the perfect default setting - to record the image the way you actually see it at the time. Leaving aside the question of whether or not the 'correct' white balance is that which renders a perfectly white object white, I'd say that given a choice between this magical, mysterious 'S-OVF' auto white balance and the conventional 'average colour = grey' auto white balance, many people would opt for the first one. I wondered for a moment whether perhaps the S-OVF white balance might be simply 'auto' + 'keep warm colours', but having checked, it doesn't look that way. Perhaps I've simply overlooked a setting which does precisely what I've just described? Any thoughts?
