APSC2 (APS-C Squared) Rotate-and-Stitch Adapter

Hi ProfHankD,

I'm finally getting around to following this up after this recent thread that you kindly added you knowledge to.... https://www.dpreview.com/forums/thread/4614646#forum-post-65701757

I've been experimenting with the 4 shots rotated arrangement (without the rotating adaptor - just carefully handheld) to get a feel for the whole process, even if not the use of the whole image circle, and am keen to move onwards.

With your APSC2 adaptor being M-mount to E-mount and my needs being Pentax K to Fuji X, I'm thinking that I'd like to borrow the idea and do a cut and shut style modification to an existing K to X adaptor. Simply slice the adaptor midway along it's length somewhere and fit a rotator borrowed from somewhere else in the middle, obviously maintaining the FFD exactly and applying the required geometry in the rotator.

That's a lot more work than 3D printing, but sure.

How do you feel about me doing that? I don't know if this rotated stitch method is your idea or someone else's, however it came to me through you so I'm checking with you if I'm jumping on your (or anyone else's) toes by borrowing the idea and making my own hardware to suit?

This particular implementation is my idea, but there have always been people doing camera motions of all kinds to stitch images... certainly long predating digital imaging. There is also the commercial FF rotator RhinoCam Vertex for medium-format lenses. In short, nobody should have a valid objection even if you commercially marketed something.
