The LF lenses all split at the board and nodal point,
otherwise you couldn’t get them on boards an. I just got my 1972
Nikon FtN down and it has a 180 ED lens but there are no nodal
markings on the gold ring. An 85mm f1.8 is also bare, but it’s
not a gold ring lens. It’s missing on a 24mm f2.8 too.
The reason I no longer use Nikons is due to their lenses
turning from infinity the opposite way from all other
manufacturers. Nikon seems to have done that to avoid patent
infringement suits after WW2. When also carrying a couple of
Leica M3’s with 21/3.4 S/A and 28 f2 lenses, the Nikon lens
really messed me up. Soooo, the Nikons had to go. They got
replaced by Canon F1’s and AE-1’s and later T90’s.
I’ll go up to the studio tomorrow and look at the Aero Ektar
180 2.5 which is currently fitted to a Graflex 4x5 SLR camera
made by David Bailey for shooting the Beatles and others.

Jan your large format lens's all (few that

Your mamiya lens I don't think have them although my
Ukrainian fisheye 30mm does. (its wrong though because it
was made for different cameras and just change the mounts.
Its probably right for a kiev 6x6
my zeiss contax lens have them and my Nikor wide angles
lenes have them and in fact the big gold line is it
usually on ED lenses. They are usually not a mark like
NODAL point but a lens stamp of some other kind.
The zeiss contax G 's I found by accident when I was
solving for the nodal point on my 28 and discovered that
the stamp for the focal range was the same place.
