New Tilt-Shift Adapter

In the 1980s I designed a tilt-shift adapter that would mount medium-format lenses on 35 mm SLR. It was not really useful because on the tiny ground glass it was not possible to do critical focus, and I put it aside.
Focus peaking now solves the problem. The current version mounts full-frame lenses to Sony E-mount and other mirrorless designs, and the coverage circle is generally enough to allow 8-degree tilt and 12-mm shift, independently and in all directions. Lenses must, of course, have aperture rings.
I have made a working prototype. I have no manufacturing or marketing skills, and no money. I need to form a team to bring it to market.
Yes, I know there are other designs out there. Mine has some important advantages.
Interested persons, please PM me, telling how you might participate.

For funds.. Create a working prototype device.
Make a video that shows how it works and that it does work then use crowd funding with an estimate on how it will cost to produce it. Business plan if you like.
THEN you can hire folks to work out the details.

I have a plate that allows me to attach my Nikons (film,/ aps sensor / full-frame sensor,) onto the Sinar 5 x 4 camera. All movements possible on both front, and rear standards. Helps to keep costs down, instead of using a full sheet of 5 x 4 film, when shooting many individual small product shots.

This Kiron (and others like it) has a serious flaw: it cannot tilt and shift in independent directions. Mine can.

While this will give you tilt, I am almost sure you are in manual mode as the mechanism will need to have all the contacts per the specific manufacturer mount to be 100% compatible. Today's modern software like PS has new tools such as "perspective warp", which allows for correction of lens distortion.

There are already versions like that on the market, you probably need something special for yours to compete!

This is a Kipon, no the Japanese Kiron lens company. I use Nikon's PC-E lenses, and from experience, I will say that not having the ability to shift and tilt in the same axis only affects me about 10-15% of the time. Though it would be nice to have. It makes me jealous of Canon shooters.

I would not be promoting a new design unless it had something special. Mine does things that the others do not, and it is ergonomically superior. Not only does it tilt and shift independently, the image does not shift as you tilt.
