    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! :o

    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.

    Eric,
    I understand that you might be willing to part with the lens. I had sent you a note about it recently but had not heard back. Is the lens still available?

    Thanks

    Hello,

    I'm looking for a 70" focal length lens for my mobile camera obscura. Did you sell yours? Are you interested in
    selling it, and what is the price?

    Thanks,

    John


    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!
