Switch from Nikon to Fuji X-E1?

Sell your Nikon stuff. Fuji adaptor plus Nikon lenses will not give you what you want. Unbalanced...

Buy a X10 as a stopgap (delightful camera!) and wait for the X-Pro2 ánd the 50-200 which is sure to follow. As a former Leica lover stick a red dot on your X-Pro and feel young again!
