I have this quixotic idea of shooting with a late 19th or early 20th century lens. I don't have any expert to converse with in person, and I'm not very knowledgeable myself about these workings, but so far my Googling has taught me this much:
1. Barrel lenses do not have shutters. Unless you want to shoot slow speeds with a hat in front of the lens, get the lens remounted with a compatible standard shutter or a "Packard" shutter (which sits in front of the lens, I guess?)
2. Some antique lenses have apertures inside, but the Petzvals and some others accept external apertures.
3. A flange and retaining ring are required. S.K. Grimes can manufacture them for a good price.
Am I right so far?
1. When shopping for a lens, is there anything I should look for in the description or printed on the front of the lens that can give me a good hint about how difficult/costly it would be to remount with a shutter, and/or what size shutter might be compatible? Or do I just have to wait until it's in my hands to attempt to measure the maximum aperture myself?
Googling turned up this:
First, measure your lens's maximum aperture opening, as this is the most critical factor:
2. I emailed S.K. Grimes, who were very nice, but their email was a bit vague on whether a standard Copal shutter might fit any given antique barrel lens. I'm awaiting hearing back, but in the meantime, are there any substantial drawbacks to a Packard shutter? If they were invented to solve the very problem I'm facing with barrel lenses, it seems like they might be just right?
3. If I buy a barrel lens requiring external apertures that slide in the little notch, are such apertures in "standard" sizes? How would I judge which sets on eBay actually fit? If worst comes to worse, and I get a great deal on some barrel lens that is a strange size, can such aperture slides be manufactured or, I dunno, laser cut?
4. A lot of barrel lens look to be around 300mm. I like that angle of view a lot for 4x5", but I thought I first might attempt this quixotic project with a view camera configured for 6x9 cm, which would make something between 100mm-150mm more suitable. Do you suppose there are late 19th century or early 20th century 120-150mm lenses out there on the market? But are the vintage barrel lenses with antique rendering all designed for 4x5 and 8x10 cameras, and thus unlikely to be less than 150mm? I suppose 150mm exactly would be a good length for 6x9cm, but the barrel lenses seem to be often portrait lenses, and 150mm is merely normal for 4x5.
Thank you so much for your expertise. I'm very early in this project, and it's already stressing me out.

- If the maximum aperture is around 24mm, consider Copal #0
- If the maximum aperture is around 30mm, look at Copal #1
- If the maximum aperture requires around 45mm, you'll need Copal #3
