I finally got around to try out A7, A6000, RX1 and RX100M3. I'm sure I'm the minority on this but my biggest problem with Sony cameras in the past has always been the ergonomics. The cameras often feel unbalanced and the buttons feel awful. I'm glad it's improving even if it is not quite at the point that I'd consider spending money. Between A7 and A6000, the A6000 feels nicer and more balanced in my hand. I just wish it is slightly taller and with a slightly deeper grip. Even though I only have a medium size hand, my hand was cramping operating the menus for a good 15 minutes. Not to mention RX1... It is nice in terms of specs but it's unusable for me without some kind of grip. Packing FF into such small body sounds nice on paper, but I think there's a point where it becomes too small for the weight of the camera.
I'm not a huge fan of EVF in general, at least not yet, even though it is superior to OVF in some ways. While EVF technology is improving, the lag still bothers me. A7's EVF is clean, nice, high resolution. On the other hand, A6000's is too low resolution, and the lag is worse than A7's. (understandably so simply from price point of view) The size of EVF is a bit too small on A6000, and of course RX100M3, to feel comfortable using all the time. I fear that I'd end up poking my eye with it had someone accidentally bump into me.
I think if Sony continues to improve ergonomics and EVF. I can see myself eventually picking up a FF MILC for travel purpose (if they ever release weather sealed body and lenses). One nice FF MILC with a high quality, f2.8 normal zoom would cover 90% of travel needs. For wild life and other things where timing is more critical, I think I'll still be relying on my DSLR for quite sometime in the future.
