Hello Scott:
Thanks for describing what you want to do. Obviously, the T-ring method
is not applicable to the Nikon lenses. I do not use nitrogen purge myself,
because I have not found it necessary with unhypered film at Mt. Pinos.
Except for Tech Pan, I do not hyper my film. I also get excellent results
without nitrogen with the Pentax 6x7, see:
