As a process lens, does it need to be used at a small f/stop, at distances beyond 1:2, etc. ?
While we're on the subject, is the same required for a 360mm F9 Red Dot Apo Artar, as mentioned by Erie ?

I know it's an inch short but one hell of a piece of glass.
I'd agree that the 14" Commercial Ektar is the way to go. A tad heavy, but plenty of coverage and usually cheaper than a 355mm G Claron.
Ken, I use the 16 1/2" (420) and 19" (480), I know that there were other focal lengths offered, see: http://www.cameraeccentric.com/html/info/goerz/p1.html
My experience has been quite positive, the Artars are scary sharp from f16 onward, as good as many other lenses from wide open to f16. I tend to use mine for product work, with a scan back, when I cannot have a reflection of the camera in the subject, they're long enough that you'd need a magnifying glass to make out the camera reflection. My 19" is planned as a wide lens for the 16x20 as well, if I can find the time to finish it.

I would think the 375mm Caltar would be the best and least expensive solution. Now if you come to Nevada and lady luck smiles you might consider the Hermagis Eidoscop No. 2 which is a perfect 14 3/4" iirc. A protar Series VIIa with 2 27" elements is 15 1/2" f6.3 combined, but no one is giving them away. The lovely B&L Portrait Unar is 14 3/4" but you said you didn't want a portrait lens. Meanwhile, take the front group out of any old 210mm Symmar and see if you really like the length very much. OK, it's late and I'm done being a smart a$$. I know whatever you end up with you'll make lovely photos with.
