Shutter suggestions

[Topsy]

Hello

The magic lantern petzval I adapted to 35mm last year has become subject to another project.

It shall receive its own camera this spring. I'll be using 4x5 sheet and cut it down to size later (the lens has an image circle of around 9cm) in order to also be able to use the 4x5 holders for another project.

I'll most likely be using Rollei Ortho 25.
‎The lens is around f2.5 (very unscientifically tested) and since it has no shutter or aperture I'll inevitably need to solve a shutter speed issue.

Easiest would be a shutter infront of the lens I suppose? When focusing the lens protudes the lensboard so installing one behind the lens would be rather hard I think.
Some kind of focal plane shutter would be a possibility too and probably the neatest as I could "bundle" that up with the film/plate holder and re-use on different projects.

Another solution I can think of would be a strong nd filter (behind the lens? or would that introduce lots of unwanted reflections?) and then do the old 'hat infront of lens' shutter. However I suspect that won't be much fun for portraits.

I suppose I could throw a Thornton Pickard shutter onto the front of the lens together with an nd filter inside it, but that might look a bit silly..

Is there anything I'm overlooking?
Does anyone have different suggestions From the above, what would you go for, and
what shutters would you recommend?
Age doesn't matter (but price does, I'm trying to do this on a budget), though the camera will mostly be wood and brass. Retaining a degree of portability would be a plus too.


In looking forward to hearing your suggestions!

You might consider a guillotine shutter. That's something you could DIY fairly cheaply. Or check eBay for an old shutter big enough to work. Sometimes you can find old compound or Compur shutters that come with unwanted lenses that you could remove for not crazy money. But finding a large enough opening may be hard since the shutter would go in front of the lens. Or maybe find an old Graflex Speed Graphic and use the rear standard and focal plane shutter. Or even pull the focal plane shutter mechanism out and reinstall it into your camera. They're fairly simple devices and not hard to work on.

Have you considered a Speed Graphic?
Aside from that, a Packard shutter might work, but could cost you as much as a Speed with no lens (as might a Thornton Pickard).

I hadn't thought of a guillotine shutter.
I think I'll try that, I've got an idea for a compact adjustable one.

I also had not considered these.
Speed Graphics seem harder to come by in Europe though. At least I don't ever remember seeing one before!

If my guillotine idea won't work I'll try my luck with a Packard shutter, I didn't realise these existed (or forgot about them entirely!).

Thank you!

A front mounted Packard shutter is not difficult to arrange. I have several of the Packards and I don’t think I paid more than $100 for any of them. I have a barrel mounted Kodak portrait lens and with a old lens board and some foam tape came up with a front mounted shutter: simple, inexpensive and reliable. It is, however, kinda ugly.
