Shooting with barrel lenses

Many of my potential LF lenses don't have shutters & often there's no aperture as well.
Having just started to shoot (rather than just collect) my 5x4 kit, I've found this causes more difficulties than adapting to digital bodies!
Looking on-line for shutters I see the range of sizes is limited & e-bay seems to want as much for an empty shutter as for a random lens in the same shutter. Either way the price is too much for me.

Restricting the aperture can be arranged with paper/card 'waterhouse stops' directly in front of the lens, or with a purchased iris if I have one the right size.

For longer exposures simply uncapping & recapping should work, but that's not an option below 1"
I have managed to get a few ancient Thornton Pickard shutters that might work & could be used with some of my lenses, but the speed range is limited even when they work well.

Things get particularly awkward with lenses like this 150mm f/1.2

Six inches across is actually bigger than any of the Thornton Pickard shutters made according to the old 1920's TP catalog I browsed, as well as any standard LF shutter...

My efforts with a 'Galli shutter' (usually 2 dark slides, but need to be bigger sheets for this beast) have so far not given usable exposures so I want to investigate other budget DIY options.
Any suggestions?

Does anyone else shoot with barrel lenses? If so your experiences would be most helpful!

Apologies for the late reply.

For barrel lenses in general, think Speed Graphic. These cameras have focal plane shutters.

I've had adapters made for hanging smallish -- not like your 150/1.2 monster -- lenses in front of Copal #1 and Ilex #3 shutters, also for hanging a Compound #5 in front of a 900/10 Apo-Saphir.

https://packardshutter.com/ will sell you shutters that open as wide as 5".

Thanks Dan, I have had a look at Speed Graphic (& the MPP equivalent) however both of these have lens boards too small for my lens (as does my Thornton Packard Ruby - which also has a focal plane shutter when I finally get it working again).
The packard shutters would solve things nicely but they cost considerably more than my 5x4 camera & lens combined - as a hobbyist I can't stretch to anything like that Sad

When winter comes I'll try using it in the dark with flash, then eventually I'll hopefully get round to building a crude falling curtain type shutter.

There's a trick for mounting large lenses on smaller lens boards. A stepped adapter. I've had several made for various big fat lenses.

One type is cup shaped, internally threaded at the front to accept the lens' rear mounting threads.

The other is externally threaded at the front to screw into the lens barrel's internal rear threads. I had these made for some TTH aerial camera lenses that were threaded internally to control stray light inside the lenses. The threads acted like baffles, were very effective.

A third type, that I haven't tried, is cup shaped but not threaded internally and with three radial set screws (I think these are called grub screws in the UK) to hold the lens in place. Ideally the screws are rubber tipped so they won't damage the lens' barrel. The adapter that holds a Compound #5 in front of a gigantic lens is made this way, but reversed.

Very clever idea - thanks for that!
Guess this is that adapter you were referring to (from your site): https://www.galerie-photo.com/1-lens-6x9-dan-fromm.html




Great to hear from you again, been quite some time we had contact... Wink

Adapting the lens to be mounted in front of a shutter, as described by Mr. Dan Fromm, is the most simple and cheap solution. That's what I did, too.
For larger lenses there are some other, even if more expensive, solutions.
- Sinar made a Copal behind-the-lens shutter;


- Linhof made an accessory focal plane shutter for 4x5 cameras, but it's scarce and expensive;
- Plaubel made an accessory focal plane shutter for Makina but, unfortunately, only for the 6x9 format.

That's it exactly.

Cheers,
