    Film holders for old 5x7 plate cameras?

    Will modern 5x7 film holders work in the old Pony Premos & Century Grands?

    Would the registry be right? I don't think so; plates and film have quite different thickness. But you could check and adjust if necessary.

    Thanks Kieth,

    Shimming or grinding for the ground glass/film plane registry seems doable.

    So am I to assume that 5x7 film holders have essentially the same exterior dimensions as the plate holders?

    hi mark

    the outter dimensions of plate holders are pretty much the same as film holders.
    i use film holders in a plate camera all the time without problems ...

    as long as you are stopped down a little bit you probably won't have trouble with
    the whole thickness-thing. don't forget that film sheaths / septums were traditionally
    installed into plate holders when sheet film started to appear on the market. the septums
    do not bring the film to the same focus plane as a glass plate. stopping down a little bit
    will probably correct for this problem.

    have fun!

    hmmm

    after reading the link, maybe i better say,
    that the plate and film holders *I* use in my
    cameras ( manhatten wizard and delmar )
    can use modern film holders without a problem
    and the modern cameras i have ( graflex/graphic, toyo and szabad )
    use wooden plate holders without any problem.
    i never saw that thread keith referenced, and i didn't realize
    that they weren't interchangeable ... sorry about that !

    i love this place, where else would one learn such random and obscure information !

    I've used a modern 4x5 filmholder in a little 4x5 pony-type plate camera. It fit perfectly. At some time in the past, a previous owner flipped the ground glass around so the matte side faces out. This would move the focus about the thickness of a glass plate. I had no trouble making a sharp image on film at about f/11 or 16. I did the same with a 5x7 Seneca Black Beauty I own and have been able to make good, sharp images on film.
