Sinar Auto Shutter--Comments!

Is the Sinar Auto shutter a worthwhile device for barrel lenses? I have
several lenses that could be adapted to this MUCH cheaper than mounting in
shutters but are there any drawbacks to the Sinar shutter system
operationally such as speed limitations?

The Sinar Auto-Aperture shutter tops out at 1/60th of a second and has no
aperture. It relies upon Sinar DB boards/apertures for each lens. I suppose
you could simply ignore the DB connections.

I've used a Sinar Auto shutter for close to 30 years with barrel lenses.
The lenses all have built-in aperture diaphrams and I mount them on
standard flat Sinar lens boards. They are also really loud.

They work great, but be careful of the tendency to try to "hang" too heavy a
lens off the Sinar front standard. Many of the long focal length process
lenses are so heavy they really require an auxiliary standard to support the
front of the lens

Out of the studio the extra weight may be a concern. May limit the wide
angle bellows compaction. Usually 90 and under go better with mounted
shutters. Upside, although slight is that all lenses using this shutter
will not suffer diverging shutter error.

If ever you feel like getting racy, for a fee equal to the rest of your kit
you can get a cable to connect the DB shutter to the rear standard so that
whilst inserting a film holder the shutter will automatically cock. A real
must have, after the Ferrari that is.

Not quite.

An auto cable, like the ones for Sinar, Wista and Prontor Professional
shutters close the shutter when the film holder is inserted and stops
the lens down to the chosen aperture.

All of these shutters are auto-cocking shutters so the insertion of the
back has nothing to do with the cocking of the shutter.
