Dear friends, just coming back to the title of this thread.. I have both, Sony A7s II and Samsung NX1, and I know very well both.
Yesterday I have tried for first time the Zeiss Distagon 28 f/2 Zf.2 on NX1, and my friends, in the screen of my laptop I've seen God. Great 3D, amazing colors, incredibly alive images, an interstellar trip. Never seen something like that on my Sony A7s II.
And the world still ignores this prodigious camera called NX1.
I know, I should get over it, but I cannot.
