So, from reading Stephen Gandy's site, the issue is that the Nikon 5cm RF lens focal length is actually 51.8mm, versus the Contax 5cm f1.5 lens focal length is 50.0 mm, and the Nikon RF rangefinder mechanism is designed for the 51.8mm focal length.
And according to S.Gandy, the issue is NOT the lens mount flange distance; that is identical for both Contax and Nikon lenses.
Okay, I understand all that.
My question has to do with the wider focal lengths, namely using Contax IIa 21mm and 35mm Biogons on Nikon RF bodies. What were their focal lengths? And for the Nikon, what precise focal lengths did Nikon use for 21mm and 35mm? They same as Contax?
Are the 21mm and 35mm Biogons perfectly fine on Nikon RF bodies, and not just because the DOF effect accommodates the issues?
