    Graflex Roll Film Holder Not 6x7?

    I just received a Graflex RH10 "6x7" roll flex holder for my 4x5. I purchased it from KEH on EBay as a Buy It Now. Shipping was fine, and it's in almost new condition. But, the frame is 2.25x2.625. That's off by an eighth of an inch, which I consider significant.

    Is this only true of the Graflex holders, or is it also true of the more expensive Horseman, Toyo, holders, etc.

    I like the quality of the images that I get off the Graflex holders. But, I would like to have a full-frame 6x7 image.

    My math that's almost 67mm wide. That's 6x7 by any measure.

    I don't believe you will find any roll film back a full 60x70 mm.

    Graflex RH holders are notorious for having a shorter "7cm" length than other rollfilm holders, say the Linhof Rollexes. No one knows why; it wasn't significant for me.

    Most 6x7 cameras that actually list the image size, like the Mamiya 7 or RB/RZ (http://www.mamiya.com/mamiya-7-ii.html#Specifications etc.) are in the neighborhood of 56x69.5mm, so expecting 70mm or so isn't too far off. Horseman doesn't list the exact dimensions: http://www.horsemanusa.com/pd_acc.html , neither does Toyo: http://www.toyoview.com/Products/Acc...s/45ACFac.html but they both have email addresses listed off their web pages.

    I just measured a frame from my RB67. It's 2.25 x 2.625...the same as you're getting from your RH10.

    Neil, you could make it any size you wanted with nothing more than a file and a little time...

    Yes, and risk overlapping shots. And if the casing has the famous pin rollers, lose whatever benefit they provide.

    I'd think that if the size was that important to the OP, then simple math, measuring the pitch across an entire roll, and calculating how much additonal you could gain, probably a mm on each end, without seeing one, would be my guess. It'd be a balancing act between opeing size and sufficient structural support for the pin axles.
