5x7 film holder dimensions/dementia again
So now I'm taking the totally empirical approach. The hell with
"standards"[1]. Can anyone who has 5x7 holders out there measure them and give me the dimensions? I'm looking for the following: o Total length & width o Exposure length & width o Retaining tab location (distance from bottom of holder to top of retaining rib) o Distance between bottom of holder and bottom of exposure opening I'm comparing these to the dimensions I found at http://home.earthlink.net/~eahoo/page8/filmhold.html. Many thanks for any who care to respond to this. [1] Like they say, the nice thing about standards is that there are so many to choose from! -- Found--the gene that causes belief in genetic determinism |

I have a bunch of E.K. holders, but I'm not sure how "standard" they are. (I'm used to seeing holders made by Fidelity, Graflex, Lisco, etc.) So do you know whether these could be called "standard" holders? Besides, it'd be interesting to get dimensions for lots of different holders and see how they compare. -- Found--the gene that causes belief in genetic determinism |

I'll ask a friend of mine who shoots a lot of 5x7 if he can help us out here. Fidelity holders are the same as the other late plastic holders. |

I have measured a few and may measure more. I don't have real accurate scales. I can do, by eye a little better than a 16th, I think. Older style Linhof 13x18: Retaining tab location - 7.625" Thickness - 0.8" Length - 9.8" Width - 5.9" Distance to exposure field - 0.6" Exposure height - 6.88" Exposure width - 4.8 or 4.9" depending; the opening for the slide is wider than the rails for the film. Fidelity Deluxe, plastic w/metal slide top 13x18: Retaining tab location - 7.625" Thickness - 0.5" Length - 8.875" Width - 5.9" Distance to exposure field - 0.7" Exposure height - 6.75" Exposure width - 4.78 or 4.88" depending; the opening for the slide is wider than the rails for the film. Fidelity Deluxe, plastic w/metal slide top 5x7": Retaining tab location - 7.625" Thickness - 0.5" Length - 8.875" Width - 5.88" Distance to exposure field - 0.68" Exposure height - 6.75" Exposure width - 4.87" only the opening for the slide as it holds film. Folmer Graflex, for Eastman wooden 5x7": Retaining tab location - 7.69" Thickness - 0.58" Length - 8.44" Width - 5.88" Distance to exposure field - 0.7" Exposure height - 6.75" Exposure width - 4.92" only the opening for the slide as it holds film. I may try to measure some more, if I have time later. That's awesome! I thank you from the bottom of my heart! Real information. |

[snip] Question: How often does one get exactly what they ask for on Usenet? Answer: Hardly ever. All by way of thanking you profusely for posting this information. It's in my file. I start work on my back forthwith. By the way, "a little better than a 16th" is exactly the standard of accuracy I'm going by here, in order to accommodate the obvious differences between film holder sizes. -- Found--the gene that causes belief in genetic determinism |

I've compiled all the sizes I have so far into a little table at http://www.geocities.com/bonezphoto/...X7holders.html.

The only markings on mine are stamped in the wood. They say, "5x7 EASTMAN FILM U.S. PAT. 2056144 1641420" (MADE?) "IN U.S.A. BY FOLMER GRAFLEX CORP. FOR EASTMAN KODAK COMPANY" The upper part has a metal piece on each side affixed to the wood with four screws. Interesting; one of the holders I got in that motley collection says (stamped in the wood) 5X7 EASTKO FILM HOLDER (on top) MADE IN U.S.A BY FOLMER GRAFLEX CORP. FOR EASTMAN KODAK COMPANY (on bottom) No patent #s, and no metal pieces for the dark slide holders. There seem to be endless variations of these devices. -- Found--the gene that causes belief in genetic determinism |

I note you used your own measurements on the Folmer Graflex/Kodak. I wonder if the disparity is wear (mine show a noticeable amount) or a different series. Actually, looking over the chart, it seems that all the empirical measurements agree pretty closely. The only disparity seems to be between the "standard" for exposure height (7.010"), and the actual openings, which are all 6.75. Easy to allow for this: I'll simply make the exposure opening in my back the size of the "standard". No harm, no foul. (I'll make the ground glass larger as well, but mark the actual exposure opening in pencil on the GG.) -- Found--the gene that causes belief in genetic determinism |
