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. :)

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.

That lens would swallow a DSLR for breakfast.

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.

Let us know when and where you post it, I'm intereted to see how much buzz it generates.

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" :-)

Talk about Bokah!

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.
