Jan your large format lens's all (few that don't) split at the nodal point no?
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.

I might be the lens and camera body king among private citizens on this list(37 cameras for some reason, most of which I haven’t uses in years), but now that I’ve been to the Lens-land box this afternoon, no lens has a nodal point marking on the barrel. I have Mamiya, Rodenstock, Schneider, Nikon, Canon, Voigtlander, misc view camera lenses like an Imagon, and some unknowns. I did not look at the Aero-Ektar, but it might have such a marking.On Jan 13, 2014, at 2:56 PM, Randy Little wrote:Depends on the lens and lens design and won't probably be on a ZOOM ever. Usually its the gold band on a nikon ED lens that sits behind the aperture ring. On my little Zeiss lens its the focal distance designator etched into the lens. On my Mamiya lenes there is non but its usually very close to the aperture ring. On my large format lenses is just usually the lens board. On a modern small format that is tele centric god only knows you have to solve. I don't own any.On Mon, Jan 13, 2014 at 1:56 PM, David Dyer-Bennet <dd-b@xxxxxxxx> wrote:On 2014-01-13 10:30, Randy Little wrote:I know about focal plane marks on camera bodies, and IR focus marks on

lenses, but I've never heard of nodal point markings on lenses. The
first two have fairly standard representations; is that also try of the
nodal point marking, and if so what does it look like? I don't recall
any mysterious markings on any of my lenses....
