Unscientific Impression: (based on jpg)
Color: Better than M240, Kinda between M9 and M240, still, M9's color inspire me more.
Resolution: Almost the best in SLR and mirrorless cameras
Focus: Thanks God! I finally know my Noctilux 0.95 can be so sharp, the dof is like a hair thin
Shutter sound: like a gun shot! But I don't mind.
Conclusion: I won't sell my M9, I won't buy M240 and I won't keep my Canons. I will keep my medium format and I will buy some more batteries for M9 and A7r. To me, just to me, it's a game changer for my leisure and travel time, but not for my works.
