    4X5 FOOT Simple Camera

    Found this on Pinterest

    I don't know how to copy to here, so this is owner's website from 11 years ago

    I know I can do that!

    Re: 4X5 FOOT Simple Camera

    I have access to a 2500mm Boyer lens, the bloke wants to sell it but no matter how I word things the post gets knocked back on this forum.

    That said I thought maybe I should just buy it myself as it might be good for such a camera obscura. But I would make it from a small (6x4' I guess) pan trailer and drive it around the countryside looking for something to point it at.

    Something I've meant to do for years, long before this lens poppped up, and realistically a pinhole would do almost as well.

    Here's a pic of it from that link.

    Just buy it, I think you know what to do with it

    I am definitely not a Civil War reenactor but did read up today, Civil War Howitzers and it struck me how they took them apart and moved them with mules could be applied to my needs, sorta

    I have a camera cart for E-bicycle, but...it's a high theft toy that cannot haul what I want

    I also volunteer as Docent close to home at a 1818 Historical Village and told them Friday I want to use old cameras at our events. I have already done this twice

    My new idea is a long handle big wheel cart this old man could slide out of my 8' pickup bed and get it back in myself or use a winch. I have 2

    Leverage

    Still doodling

    This is the lens



    It's EIGHT INCHES across

    Projects a 1m circle I'm told, 2500mm focal length so presumably that's at approx 2.5m back from the lens, I doubt that it's a tele.

    Mounted in a box the size of a trailer it might work, then drive around the district looking for something I can point it at. Maybe using 30x30" paper as a neg.

    I'm only dreaming, I don't even have a darkroom these days and not sure I want one again anyway. But it would be soooo cool.

    Don't know, it's about 200 wide so 2500/200 = 12.5, maybe f12.5 ish.

    It seems I was bang on.

    EB adds that the 2500/12.5 Apo Saphir “ was built for the military. It was used, among other purposes, for filming nuclear tests (whence the front cover) and one is (was ?) used for wide field photography at the Meudon astronomical observatory. This should give those acquainted with astronomers’ demands for quality an idea of how well corrected the lenses are.”

    So if wet plate: Coat and process while you are actually inside the camera body?

    That could be made to work if the camera-built-into-trailer concept is used.

    Back into scenic overlooks and shoot at fixed infinity. Panoramic formats might be easier to physically handle the glass plate; smaller yet still "big".

    There are only three types of mounting flanges; too big, too small and wrong thread!
