Some of you guys are driving yourselves crazy trying to figure out how to cram a good petzval into a Copal 3 shutter to fit on the Arca Swiss.
The far better solution is something like this old dawg here. A platform, if you will, for barrel lenses of all types with a shutter built inside. This takes common 6X6 inch lens boards like the old Kodak 2D had, easy to make, for all of the ecclectic barrel lenses you've been wanting to experiment with.
Inside is a Packard shutter that I've serviced which is running flawlessly. Just find some 1/4" sprinkler tubing and a bulb, and it's ready to go. It has 1/25th instant speed with the pin in place, and without the pin, it can achieve anything from about 1/5th to forever. The back is an old fashioned slider that puts two 3 1/2 X 5" images on each sheet of 5X7 film.
The lens is a rebranded f5 Wollensak brass Petzval Series A 9". Perfect for this application. If soft focus is what you're craving, take the rear group out all together, and put the front group in the rear for a lovely 14 ish inch achromatic meniscus! The old Hyatt lens has no aperture blades. Wide open all the time, but trust me, that's the whole point!
Priced at the sum of it's parts. I may have to just part it out, but I hope someone will seize upon the value of the outfit. I figure camera with sliding 1/2 5X7 back 125, packard 60, and lens 225, so I'll ask $410 + shipping for this. My labor to assemble the pieces, and service the shutter is FREE
