Thanks bojan.
I have the excellent Nikon 300mm f4 + 1.4 T/C for imaging.
@ Ken.... Thanks for the input and in particular to hear what I had in mind is feasible. I had to do a refresher on the designations for small sensor sizes, so thanks also for that.
I have an unused lens mount ring that I can get drilled and threaded to fit three alignment screws as per your illustrations.
This is what I love about forums, getting the right advice to turn ideas into realities.
Cheers
Kev
