One thing I’ve learned since shooting micro four thirds… I really don’t like the 4:3 aspect ratio at all. It may have some uses… perhaps for people shots or certain portrait orientated shots, but for landscapes, cityscapes and most street shooting I just can’t work with it. I’ve grown to hate its boxy, dull, motionless character. I have no long 35mm film history that ties me to 3:2 either; I just prefer it.
I think I’m going to switch the GX7 to permanently operate at 3:2 even though it reduces the active pixels to just over 14M. I simply don’t ever use the extra height and would rather compose in the viewfinder than crop during post processing.
I was a little worried about the aspect ratio before moving to M4/3 and it seems my concerns were justified. It’s no big deal, quite a few photographers shoot m4/3 cameras in 3:2 ratio and at least I’ve learned what I do and don’t like.
Maybe at some point in the future I’ll come to appreciate the 4:3 aspect ratio, and in theory a photographer should use whichever aspect ratio is appropriate for the shot… but right now it simply isn’t for me.
