Tin Can, here is my solution for my arca. It wasn’t the best solution being mounting the shutter behind the lens.
The arca bellows are simply too small for 5’ hole packard shutter.
The machine work is done by Gidou-san of Toyo Camera Service in Tokyo.
Here are the samples of attaching a 5 inch hole packard shutter of Packard-Ideal Shutter Company to Dallmeyer 3A and Graf variable 14’-16’.
I wanted the packard shutter attachment system to be versatile to most of the large diameter lenses.
The system can use Lee filter SW150 system. I need a lens hood for this system now.
I bought 1, 2, and 3 prime numbered ND filters so I can use 1 ND filter or combine 2 of the 3 ND filters to reduce lights down from 1 to 5 stops depending on the ambient light intensity. The instantaneous mode speed of the 5’ hole packard shutter is 1/10 to 1/8. I use ISO 50 and ISO
100 color transparency films currently.
