In case you don't make it over to the medium format forums, I hope you enjoy my PDN PhotoPlus coverage which has a couple of interesting products for 35mm camera users. These are the Cambo Actus and the Arca-Swiss Universalis which offer a view camera experience (and features) to 35mm cameras, especially when coupled with powerful cameras like the Sony A7r / A7s these little view cameras can pack a punch and don't have to be used with expensive medium format digital lenses, but can get a lot out of relatively affordable medium format lenses (with their large image circles) for stitching and perspective control purposes.
Given that there aren't any compact tilt-shift lenses for mirror-less systems, and there are relatively few focal lengths available for standard tilt-shift lenses from Canon and Nikon these miniature view cameras could be worth a look. It's also nice that they have expandability into medium format without the need to buy a whole new system (simply changing the rear standard or mounting plate).
You can read more about them on my website AND watch full-videos presented by representatives of the manufacturers on my website;
