I use full frame lenses on my Fuji using the Kipon tilt-shift adapter. I believe they make a shift only adapter that is cheaper if shift is all you want.

Here's a bit of advice when selecting a lens. Be aware that you will not get automated lens corrections when you attach a lens using these adapters. On top of that, when you shift a lens you cannot even correctly apply a manual lens correction profile since the distortion shifts when the lens is shifted.

I suppose this is one reason dedicated tilt shift lenses are so expensive. The optics have to be designed for almost zero distortion. So when adapting a full frame lens for shift purposes you need to use a lens with low distortion.

When you tilt a lens, the relationship between the focal plane and image plane change - that is they are not longer parallel. That is known as the Scheimpflug principle. Any lens distortions will be magnified because of this when the lens is tilted.  This is particularly true for field curvature.  View camera lenses (and tilt shift lenses) are expensive because not only do they need a large image circle but they also require minimal field curvature.
