I, practically, use my XT-1 all the time but have retained my wonderful Nikon D3. This is, mainly, due to my also having the marvellous Nikon 24mm PC-E Tilt and Shift Lens.
There are, I think, some Landscape scenes which can only be fully realised by using the T&S Lens as well as some architecture shots.
I, speculatively, bought a Novoflex Adapter. However, although it fitted reasonably well into the Fuji I had to use far too much torque when trying to fit the Nikon lens into it. The tooling was, at least on this particular adapter, very poor. I had to send it back.
So :-
a) Am I chasing a flight of fancy in trying to adapt the lens to my Fuji?
Would a far better option be to just lug my DSLR across moorland/stiles and rivers on an aging back and legs?
c) Has anyone achieved the adaption of T&S or other Nikon lenses successfully?
