Thank you very much Spyro! It was really my pleasure to answer your questions, not annoying at all.
I'm a bit surprised by the glow you mention. The ZM is known to be too contrasty for some users. Just a guess, maybe the sensor has not been cleaned properly, leaving a film of shutter oil causing the glow, in which case a wet cleaning should clear it.
As for colors, I would recommend that you use the embedded profile instead of the adobe standard, in case you use LR. 5500/15 white balance is a good starting point that works well for most daylight shots.
