    This is also true of the Linhof. The 56x72mm format has more image area than 6x9 sheet film and has the same proportions as 8x10" along with the convenience of rollfilm, and 3 backs will give you plenty of development control (bearing in mind that you have 10 exp/120 roll).

    6x9 sheet is narrower and longer, and you get the advantages of sheet film, being quicker operation with groundglass focusing, individual development control, and more flexible neg filing. In theory there should be a film flatness advantage with sheet film but the film flatness of the Linhof backs is so good, I don't think this is a big issue.

    Mamiya I think made a 6x8 120 back for the RB. Not sure about the RZ. They even list the coverage of the various lenses. Or at least I remember they did.

    OTOH I'm still not sure what the OP is looking for A smaller 4x5 camera? A camera using smaller sheet film?

    If she wants a smaller camera not much point suggesting a big RB over a light weight 4x5

    "6x9" sheet film is made to fit in 6.5x9cm plate holders, and the image area in a 6.5x9cm plate camera with film sheaths is 61x87mm. That's a lot more than 56x72!

    I guess I should qualify that. If you use Graphic, Lisco or Fidelity 6x9 sheet film holders the area is smaller (I don't have any handy at the moment, but I'll measure when I get home), but if you use a Linhof 6.5x9 sheet film holder (which uses a slightly larger sheet of film, but fits in the same back), I think it's larger, and then Ole's plate holders with film sheaths may be something else yet.

    Um, David, there's not quite a standard for nominal 6x9 roll holders (not relevant, but usually with smaller gates that sheet film holders) but the ones I've measured are on the order of 56-57 x 79-82 mm. In other words, larger than your 56x72.

    Are you sure that you didn't mean to say that 6x7 is larger than 6x6?

    Cheers,

    Dan

    Let me check when I get home, but my sense when I started shooting 2.25x3.25 sheet film was that the image size was surprisingly smaller than I had expected, and didn't offer much advantage over 56x72mm, except that it was narrower and longer. I'll measure everything and report back.

    The 'window' of my Graflex holders are 52mm x 78mm. So 2x3 sheet film is narrower than 120 rollfim.

    Ulrich, please check. I have one each RH-8 and RH-12, both have gates around 56 mm high. With both, exposed films have an unexposed strip about 2 mm wide top and bottom.

    I have negative carriers for my enlarger - one will accept 2x3 sheet film but is too narrow for 120. I'm not at home to actually measure them.

    I have just measured the exposable region. The outer Window is 54mm x 81mm. my holders are made of wood. May be there are newer ones of plastic or other material with different dimensions.
