Swebo TC24 24mm f/3.5 Lens


This may sound a little off the wall, regarding the Sweebo TC24, but I have a rather rare Leitz 2 part adapter #500935 that was included with my Leitz 25mm f2.5 Photar macro lens to attach the lens to my Leica R bellows. The outer removable portion of the inner ring is 40.5mm. The other inner portion of this adapter has an microscope RMS thread to mount the photar to the outer portion of this adapter. I also have a rather heavy custom made adapter ring that was made to mount my Rodenstock 75mm 1X and 2X Apo Radagon D lenses into a Copal shutter. As it turns out it has the same 40.5mm thread size that screws into the Leitz adapter (which has a Leica R mount). The other side of this custom made adapter is M39 size (same as all of my Apo Enlarger lenses) and also the thread size of the Sweebo TC24 lens.

Since the Sweebo TC24 lens appears to have the helicoid focus and the Cambo Actus Mini foucses via a bellows, with the possible exceptions of added vibration and not being kept parallel to the lens board, do you see any problems mounting the lens into the outer portion of the #500935 Leitz adapter and the special custom made adapter ring providing I can still focus the lens at infinity with the focus of the lens itself?

The reason that I am asking and suggesting this as a possiblity is because I believe that I could then mount the lens this way to my Cambo modified Leica R lens plate and mounted this way it would not interfere with releasing the lens from the Leica R plate. Don't forget the Sony camera bodies have an 18mm flange distance while the Leica R flange distance is 47mm. An advantage for me to do this is that I could carry the Sweebo LS24 unattached to a Lens plate and only attach it when needed; this would take up less of the precious space in my small backpack.
