If it was a Letus (or similar) then the adapter actually takes the image
from the lens and projects it onto a surface that the camera views -
hence you don't lose a part of the image like you would if you used a
(say) 35mm film lens on an APS-C body. Most professional use video
cameras have 3 chips in either 1/3 inch, 1/2 inch, or 2/3 inch sizes.

Might not have been exactly that one, but yes, something very similar.
It didn't have the offset rails. The rails on the one he was using went
all the way through both front and rear mounts.
I remember him saying something about a 1/2 inch sensor and a spinning
or vibrating ground glass.
Three chips? Separate sensors for RGB?
The guys at the camera store didn't know anything about his video
camera, and he didn't know anything about Nikon camera lenses, so they
were having a fairly interesting discussion.
One of the lenses he looked at seemed to be the Nikon equivalent of the
FAJ lens (i.e. no manual aperture ring) and it defaulted to fully
stopped down when he mounted it to the adapter. They were trying to
figure out how to force it to stay open all the time, because it was
just too dim.
