I'm not sure I'm understanding your issue exactly but I owned a TC many years back and regularly used it successfully as Dynachrome has described. My camera prior to that was a Zenit E (Russke rig w/M42 mount) and I had some accessories and lenses that worked well in this manner. I'm attaching a scan of the pertinent pages from the TC manual in case you don't have one. Forgive me if I've missed something and your application goes beyond the scope of the material..... I imagine that an aperture priority camera would possibly adjust shutter speed to coincide with the closed down, un-coupled lens while the Konica forces you to select a shutter speed for the meter to coordinate with?
