    Hello,
    I considering parting with a large format lens that I have had for many years. Here is the basic information from the rim:
    C. P. Goerz A.M. Opt. Co. Apochromat ARTAR 70 in. F:16
    Physical dimensions: Approx 6” external diameter. Approx 9” length.
    The lens itself weighs just over 19lbs.

    It was used on a custom built, large format graphic arts camera and dates back to the late 40's or early 50's. It is still in very good condition and has a custom wood storage case. It has been locked away in a safe for about 20 years and I have decided that it's time to finally part with it.

    Anyone know of sources other than eBay that would be a good place to list such a lens? I know there has to be a very small market for something like this but also want to make sure it ends up somewhere that it can be used or maintained in a collection. If nothing else, it makes a wonderful conversation piece!

    I have posted a few photos of the lens.
    (The CD shown in the one photo is just for a size reference.)

    Thanks in advance!

    Eric

    eBay. There are probably only a handful of people in the world that would want a 70" lens and eBay is the best way to find them. Run of the mill crazy people with normal 20 x 24 process cameras aren't likely to have enough bellows length for that lens, but hey--maybe someone is turning their house into a camera. :smile:

    You can try listing it on the Large Format Photography Forum:

    http://www.largeformatphotography.info/forum/

    Bear in mind that there's a 30-day waiting period there before new members are allowed to post in the classifieds.

    But yeah, even on the LF board, potential users of a 70" lens will be few and far between.

    There was man in New Orleans who had a huge vacuum frame (15' + long) on rails in one room. The other room had a similar, smaller frame for E size sheets of film, also mounted on rails. The wall between these two rooms was his "lens board". No doubt he had a lens not unlike this one. I wonder what happened to that lens.

    I built my 20x24 field camera to use this length lens, but I honestly can't imagine actually doing it.

    You could put this lens on a 4x5 and do large format bird photography with it. That is a massive lens.

    Heavy lenses are a PITA. I have a 1200 mm Apo Tessar which I would love to use but at 23 lbs it needs it's own tripod. It was ok on my big enlarger but otherwise a paperweight.

    Wowzers, that would be almost 2 yards (almost 6 feet) of bellows just to focus at infinity. You may find tire kickers but few takers no matter what the price.

    I'd love to have it -- I would make a solid bellows 5x7 or 8x10 camera just for it (depending on how big the moon would be on the film. But I could not afford it, unfortunately...especially for the one or two images I would make with it.

    Who knows how big the moon would be on the film with a 70" lens?

    70 inch lens. 1/2 of that is 35 inches. 1/2 of that is 17-1/2 inches. 1/2 of that is 8-3/4 inches. So, three doublings of an approximately 9 inch lens. Each time you double focal length, magnification doubles. Therefore, the moon would be (2x2x2=) 8 times larger than it would be with a 9 inch lens. If the moon is 1/8 inch in diameter with your 210 - 240 lens (and I think that sounds about right, from last time I shot the moon with a 210...though it was several years ago), it would be 1 inch in diameter with this lens. Hardly worth using sheet film, unless you were doing double exposures wanting to superimpose a giant moon onto another picture. I'd do it with a 6x4.5 instead.

    Dang -- hardly worth it then -- I might as well hook the beast up to a 4x5 with a roll back.

    Thanks.

    If you use it as a telescope with an eyepiece and a film back where the eyepiece focuses, you can more than fill a 4 x 5 with the image.

    The depth of field on this beast must be about 1/64" :smile:

    Actually, Richard Ritter is currently building a 20x24" camera with 90" of bellows. So, Richard may know a potential buyer for this lens.

    I know a guy looking for a lens to cover a wet plate camera he is building that will shoot a 6' x 6' ( yes that's feet..how crazy is that?) plate with 12 feet of bellows. He may be very interested in this lens. Robert

    The references to using it as a telescope may be something to consider. Some amateur astronomers build their own telescopes, and that may be a good audience to target if you list the lens on the auction site.

    It will cover (sharply) a plate about equal to it's focal length, or a plate with a 70" diagonal. Artars are generally acknowledged to cover about 46 degrees, but they will at least illuminate quite a bit more than that, much of which may be perfectly usable for contact printing.

    Focal lengths longer than about 35" tend to bring relatively less because as one person noted, very few people have both a camera that can support it and enough bellows to use it.

    The "sweet spot" for Artars is IMO 30" and 35". possibly up to 47-1/2" although that's stretching a bit. In these focal lengths a larger number of people can use them and there are few alternatives. 24" and shorter, lots of choices and Artars bring much less.

    Your lens is rare and has some value as a collectors item, especially with the box, caps, etc. Coated 30" and 35" Artars will bring $750-1000 in barrel on a person-to-person sale, and $1,300-$1,500 in shutter (based on eBay sales and personal purchases over the past two years). Red Dots will bring more than non-Red Dots, and pristine coated lenses with caps and box always bring a premium. Your lens seems to have a 78XXXXX serial, so it's a coated lens made just prior to the Red Dot series. I'd guess your lens would be worth $2,000 - $2,500, but that is a guess and you will be looking hard for a buyer unless it's bought for the collector's value.

    Hope this helps.

    Cheers, Steve

    OMG... the handle for setting the aperture is almost as big as a cars gear lever! :surprised:

    Wow, I just found this thread and that is a large lens. I just recently acquired an 11x14 Studio Deardorff which uses 8x8 lens boards. It would fit, but I may need to acquire a third bellows extension to fully realize its potential. But before that can happen, first I need to see what my newly acquired 11x14 Wollensak Varium f4 will do. I just cut a hole in an 8x8 board large enough to handle the flange which is 6 1/2"+ across.
