A 35mm lens on a MFDB is not enough for professionel architectural work.
Better you use a Linhof Technar or Sinar artec, both have sliding backs and they can handle a 23mm.
With the Linhof you can use your lenses(changing plate).
The last days I used liveview with a laptop mounted on the tripod of the camera.
It was easier than I expected.

enought for me... anyway, if sometimes i need to go larger i can stitch !
in 4x5, my shorter end is 80, but i prefer to use the 110 if i can.
in 6x8, i use a superb 58xl linhof selected
in 24x36 5D markII i use 24 TS-E, ans few times i use stitching.
Anyway, i will be able to buy a 23 later, and use it without the sliding back !
