Mounting barrel lenses...

[PViapiano]

Hi all...

After reading posts by many using old lenses, I got to wondering how these lenses are mounted if you're not using a shutter?

I've read about "iris holders" but don't know what they are. I'd love to find out more...

Are there any sites showing how barrel mounting is done or sites where I can look at these iris holders?

Thanks...just trying to learn more!

Really mounting lenses is just a big exercise in making lensboards yourself, then drilling a hole just tight enough to fit to the threads of the barrel lens. At first I was using oak, but found the lens boards exploding along the grain from the stress of being stretched by the lens. I hear that plywood works better however. That's how I get them on the camera... after that, I've been currently using a 'Jim Galli shutter' (waving darkslides in front of the lens. But I will soon move up to using what's called a Packard Shutter.... mounted on the front of the lens.

Fuck all that. Just get an iris universal lens mount. It's a big iris that closes down over any lens, forming a light tight seal and obviating the need for individual lens boards. You can get a packard or luc shutter or a fucking hat and you are set.

Paul, most barrel lenses were supplied with a matching threaded flange. The flange is mounted on the lensboard with a set of small screws, and then the lens is screwed into the flange. Here are some crude little digisnaps I just made of an example from my collection - this one's a 6 1/2 x 8 1/2 B&L Tessar Ic on a 6" Eastman board.

Except you have to win the ebay auction... which means $$$$$. people have been jamming lenses for years and years, it's nothing revolutionary Having the universal lens mount is nice, but it's not necessary, and plywood is cheaper.

But why do without a shutter? Lens on board on Speed Graphic is one way to get timed exposures with a lens in barrel. Another is front mounting, but an adapter to hold a lens in front of a shutter is rarely cheap.
