    I thought the Home Portrait Graflex was a 5x7.

    I think these were generally made with 5x7" Graflex cameras, because they were big enough to mount the lenses, but were used with 4x5" backs. I suspect the long lens barrels may have vignetted the image on 5x7", and they were likely to be cropping from the 4x5" frame anyway.

    I like that the photographer pictured in the PS Bertha article was wearing a suit too!

    Here I go...

    Hogwsh! @ Goldfarb. quoting "I suspect the long lens barrels may have vignetted the image on 5x7", and they were likely to be cropping from the 4x5" frame anyway."

    The barrel is just a way to mount the lens and keep stray light out... has nothing to do with coverage. I had a similar lens (not that long of focal length) and it could illuminate WP just fine. let alone the 5x7 it was designed for.

    The owner of the camera I saw said that the vignetting never showed on his pictures, though in truth he's a collector more than a photographer, I think.
    In a related story: at the recent PHSNE Photographica, I was convinced to take a 4x5 RB off the hands of another dealer at a low cost ($50) that I then turned around and gave to another dealer because I had too many projects. It had a way big flange for the lens mount that was pretty obviously factory installed in that it wasn't attached to the front but was the main front standard of the camera, welded in as all of them are. And there was no flip-up door, no broken hinge or place where one had been. I mean the threaded opening was well over 75mm. In looking up the Big Bertha last night, I found that the Graflex site has a few pictures of 4x5 versions made by the factory with 20" Wollensak telephoto lenses. Here is a George Eastman House page on one. I wonder if the one I passed on was a body from one of these.

    Turns out the other projects I bought (5x7 and 8x10 view camera bodies that need work) are less likely to be interesting in the long run than the one that got away... I guess it works out like that sometimes.

    Hmmmm, I remember that camera. I think your speculation may be spot on!

    The Star camera that started this thread looks like a 5x7 rather then a 4x5 like was already mentioned. I've head of them making them and mounting a 4x5 revolving back on them since 4x5 film was more commonly used by the photographers using these cameras. The biggest one I've seen was a 5x7 with the most absurdly large lens on it. The thing pretty much required two people to move it.

    Anyway, if anyone knows anyone interested I'm actually selling a relatively reasonably sized 4x5 Big Bertha right now. I tried offering it to the APUGers at a discount first but now its up on the auction site.

    The lens has plenty of coverage for a much larger format than 5x7", but put it on an SLR with a long barrel, and I wouldn't be surprised if there were some mechanical vignetting at wide apertures, just because of the way the mount is constructed. It's not like having a tapered or square bellows with no obstructions between the lens and the film.
