Sinar Copal Auto Aperture Shutter f5.6 for Sinar DB Mount Lenses

Sinar Auto Aperture Copal Shutter f/5.6

With the Sinar Auto Aperture shutter you can mount Sinar DB mount boards and have consistent speeds across al lenses, as well as enjoy discounted prices due to their lack of attached shutters.

I have tested that each speed is functioning and the the shutter blades close and open as expected.  The speeds sound consistent, though I have not professionally tested them.

There are NO CABLES INCLUDED with this shutter, however I performed the tests with my own cable.

The slightest issue worth mentioning is  when using the red button on the side for preview mode, sometimes the iris does not completely open and some assistance is required via the lever.  I wanted to post a picture of this, however, the shutter functioned properly each time I tried.  (camera shy I imagine :-)
