I would like to extend the OPs question:
What possibilieties does the GFX offer for tilt-shift shooters (expecially for architecture in my case)? What would we need to have a capable system with all the necessary focal lengths?
1. The announced adapter plate for view cameras (
http://www.fujifilm.com/products/digital_cameras/accessories/others/#vca) will only work for longer focal lengths. The grip of the GFX has some depth and would interfere with the adapter plate, so the adapter plate will have to have to have around 40mm or so distance to the sensor. So view camera lenses with wider focal lengths won't work because they are very close to the sensor.
2. The adapter for Hasselblad HC lenses is a great start, but it does not allow movements. BUT - if I was Cambo or Arca or Alpa, I would take the adapter apart and use the electronics (or ask Fuji if I can order it seperately from them). They could use that and combine that with their view cameras like Cambo Actus or Arca F-Universalis. Or even their pancake cameras like the Cambo WRS. They would need a cable connection between camera side and lens side of their view camera. Compard to the solution both Cambo and Arca have developed with their lens boards for Canon lenses this would have a big advantage: they could control aperture directly, from the camera, they have exif data in the files. Would be amazing. The HC 35mm would be about 28mm (in 35mm equivalent values) the HC 50mm about 40mm.
3. That are the widest usable Hasselblad lenses as far as I know - the wider ones have a smaller image circle and would not allow movements on the Fuji. So - what are the choices for wider focal lengths that I definitely need for my architectural work?
4. There are other great 645-system lenses that would work. Contax 645 or others, but the widest focal lengths are usually 35mm. Only the Phase One has an 28mm, but as far as I know itβs not that great on the outer parts of the image circle.
5. The Canon TS-Es have an image circle that allows for some movements - not as much as on the smaller sensor of a Canon full frame camera, but enough for most use cases. The TS-E 24mm L II would become a 19mm equivalent (in 35mm terms) on the GFX, the TS-E 17mm a 14mm equivalent. You could use the Canon TS-Es with a Cambo Actus or Arca Universalis. But the problem is the grip of the GFX which is quite deep. I combined product photos (scaled to the same size) to check this. Look at the attachments. It will work with the Cambo Actus with camera in landscape orientation, but not in portrait orientation. With the Arca Universalis it will probably not work at all, because the Arca lens board is wider (definiteyl not with portrait orientation). So to be able to use the TS-Es on view cameras Cambo or Arca would have to redesign their Canon lens boards. Should be possible.
6. What I would prefer is a smaller pancake camera like a narrower version of the Cambo Wide RS. Narrower beacuse it should not interfere with the camera grip. That would be the most amazing solution.
