Konica C35 EFP flange distance?????

If you are pulling the camera to pieces anyway, it should be fairly easy to measure the flange distance yourself.

Measuring from the film plane to the rim that holds the rear element is quite easy. Set the lens to infinity and use a piece of glass or metal on the frame window near center and subtract its thickness of the measurement you get. It's not a flange film distance as there is no "flange" in that sense in a compact 135 camera. Conversion design should allow some tweaking for infinity calibration.

+1 again. There is NO FLANGE. The lens is an integral part of the body, so where the flange ends up is a function of how you slice it....

I suspect it's too short for tilt/shift on MFT, but maybe not?

On MFT it will be hard for tilt/shift I estimate, too short distance from the lens rear to the sensor to suit the MFT register distance of 19.25mm. Probably at most 5mm to fit a shift/tilt mechanism. The lens is sort of a Tessar design, fixed focus, aperture probably primitive as well as it is linked to two ISO settings.  Fixed 1/125 sec shutter time. No real exposure measuring but a low light warning.

It seems Andy Warhol was fond of a sister camera model, that usually says enough for me about the technical aspects.

Unfortunately, mine was stolen decades ago. However, I bought one a couple of years ago thinking that maybe it could be adapted in some way -- hopefully not as challenging a conversion as this . I was actually thinking about using it with a LED array as both a low-res sensor and a projector... I even had an undergraduate senior project team work on doing that, but they ended-up targeting a 6x6cm TLR and didn't get very far with the project....

Yes, I recall that Konica hybrid. Really fine tinkering. More as a challenge than going for a usable solution, like so many DIY projects.

Some years ago I salvaged the lens of a Ricoh FF!, the Color Rikenon 35mm 2.8.   3D printed parts to clamp it with and glued that to a reverse Sony FE adapter.  Today  I measured the distance of the rear element rim to the Sony A7RII body mount flange. Given that the register distance of the Sony is 18mm and that of an MFT body 19.25mm there is about 9mm to get a tilt/shift mechanism in between that also has to include the adapter flange thickness of say 1 to 1.5mm.

Older version of that lens adaption:
