Ok, I have got a 2D Kodak as a "dedicated" portrait camera. I am going to use three lenses in barrel on it. I have lens No.1 with me now: a Dallmeyer 12" f3.5 Portrait lens with front diameter of 4" and back diameter of 3 1/2", 4 1/4 " in length and about 7-8 pounds in weight. The other two lenses on the way are 36cm and 42cm Heliars. I don't have their dimension yet. I will use these lenses in natural light.

A few days ago, I thought I would install a Packard shutter behind the front standard like Jim Galli did. I am still leaning toward that option. But I have read on this board that some users have good experience with Sinar auto shutter. I would like to have some advice from both sides, preferably with people who have used both shutters. I have a Deardorff with a dozen of Dagors and Artars in shutters for my landscape use. The shutter I am going to put on will be used for big and heavy barrel lenses only.

Thanks a lot.
