Might want to look into the use of DB mounting of lenses for Sinars.

The lenses you looked at likely had aperture controls, but are intended for use of the Sinar Copal shutters.

It should be a much more clear if you research Sinar DB mount and Sinar Copal Shutter.

Hi Len,
Thanks or the direction where to start looking.
just read 3 pdf's for the DB Lens system, still in the fog,,,

Have you seen a Sinar Copal shutter and know how it works, and are you looking at buying one?

Are the lenses you were looking at DB mount lenses? DB mount lenses are essentially functionally barrel mount lenses, and need other means to control exposure duration, with them designed to work with the Sinar Copal shutter.

To use the Sinar Copal shutter, the rear of the lens cannot interfere with the large shutter opening and needs to mounted clear of it.

It might be a little more obvious if you saw the Sinar Copal shutter mechanism and how it mounts to the Sinar standards and DB lens boards.

Sinar re-branded Rodenstock lenses as "Sinaron'". These were often sold as part of an outfit along with a camera, case, and accessories.
They were offered both mounted in Copal shutters, or in the DB mount to sit in front of the Sinar/Copal shutter.
The DB lenses are less expensive on today's used market because they work only with a shutter-equpped Sinar camera.
Of course the Sinarons mounted in shutters can work on any view camera, so are more expensive today.
They are all very fine lenses, in numerous variations that correspond to the Rodenstock product line.

There are a few benefits of using the DB system. You have one shutter for all lenses, so you get consistent exposures. You can control the shutter (opening/closing/dof preview/setting ss and aperture) from behind the camera. There's also a so called interlock cable that connects to the shutter and the back of the camera. It enables automatic closing of the shutter when you insert a film holder.

Downsides for field use include complexity, reliance on one shutter, potentially weight. It depends on your alternative setup.

The system is most relevant for studio and close-up use in my opinion, but there are other benefits of the individual parts outside the system.
Having the shutter means you can use "any" barrel lens you can mount on a board (there are some physical limitations). They are often cheaper and often have more aperture blades. The regular lenses mounted on DB boards are also cheaper, because they don't have a shutter.

The Sinaron S lenses you mentioned are all relabelled Rodenstock Sironar-N series lenses. If you want to shoot them on the Kardan you need shutters and linhof boards for them. There is no difference between the Rodenstock shutter mounted version and the Sinaron versions you mentioned. For example the Sinaron S 240/5,6 will unscrew from the DB board and go in a copal 3 shutter without problems.
