.....It should be possible to make a small camera with a FF sensor and F mount.
I am only suggesting a FF Nikon version of the Sony NEX 3/5 preferably with a viewfinder like this Fuji.
What is more interesting than the Fuji is what comes after. Hybrid built-in viewfinder is great. And stabilization. Hope Nikon could do it and then Canon will follow?
But first, let's see how good the Fuji is...
