i also found that the Alpa HPF ring for the SK43 does not quite fit the cambo mounted lens. this is a puzzler.
since my cambo lenses are T/S, it would interfere as I assumed, but I expected the inner diameters, where the HPF fits onto the lens rings, to match. They did not.
I spent the day diddling around with the HPF rings for the 70 and 43 to get them to work with the T/S cambo lenses. Had to machine off the knurled part, which ends up losing the clamping screws. This is to clear the T/S shafts. This required i make a little tie strap for locking the ring halves together. Next i have to make new extended knobs to clear the HPF. Almost there. Best part is no cambo parts have to be modified, just the knobs replaced.
