I've seen this lens offered in barrel or in Studio shutter. Mine is the f4 version with diffusion control and is in the Studio shutter. I'll be honest. I despise these shutters, but I really like this lens. I've not had good experiences with these shutters in the past. On this sample, I have a Wollensak "Let the user judge" front cap and have used it as a barrel lens instead of with the shutter. I'm contemplating the thought of this in a non-Packard shutter that will sync with flash.
What are some shutters that you have seen this successfully mounted in, without losing any stops due to shutter size limitation? Copal 3 maybe? It looks like it would be tight, if possible at all. Maybe an Alphax?

Thanks,
Chris
