Same experience here. My guess is most people view their photos on their phones, via Instagram or Facebook. Rarely are photos looked at in full size on a high quality monitor.

I have no intention of giving up my Olympus mirrorless system. I'll probably add at least one more lens to my collection next year - I've been relying on my 12-40 f2.8 for portraits, but I'm liking what I've read about the Sigma 56 f1.4.
