Is it possible to set the GX7 so that in live view the histogram shows the effects of adjusting aperture, shutter speed, EV compensation? Comparing the GX7 histogram with that of Olympus (EM5 and EP5), in live view it doesn't seem to offer much help to the user in determining the correct exposure. The histogram just seems to show what live view is showing, I.e a fairly unchanging value irrespective whether the aperture or SS is wound up or down. The histogram displayed during review is a different matter, it reflects under or over exposure. I'm finding the out of the box setting pretty useless, what do I need to do to make it mimic the Olympus way of doing things? Hope someone can help me on this. Many thanks.
