When Sony announced their new A7r, I got excited and placed an order. I was going to use it with my Leica M lens collection.
But a week later I realized that what new camera is not really that much more than my old one (I use Ricoh GXR with M module). Tech is the same, I decided to wait out for something Revolutionary, not just evolutionary.
So the camera order got canceled, and the money will be saved for something more useful.
