It was my first time to see such a modular lens...
The inner lenses are mounted in threaded lens holders. All of the lens groups seem to have matching threads, even the back lens, so I could rebuild the lens like this:
() )( )( S ()
() S () )( )(
() S )( )( ()
I think the seller was genuine, maybe made a mistake while cleaning.
For me here in Australia, cost of shipping makes returning a very expensive option, so I'll be keeping the lens.
If I was in the USA I probably would not.
It seems to cover 8x10 - I'll post a sample this weekend for anyone interested.
Thanks for your comments everyone.
Here's a quick paper neg I just took with the 14" apo artar...- the lens seems sharp and clear:
On my screen it looks very soft. Could be the scan, could be my screen.
And there's no detail discernable in the corners so assessing coverage is impossible.
And it is a closeup shot so even if there were detail in the corners assessing coverage at infinity is impossible.
The Goerz 14" Apo Artar must be very different from the lens I have which is a Goerz 14" Apochromatic Red Dot Artar. I use mine more than any other on my 8x10 and it has lots of coverage and is very sharp. I do mostly still life but I have taken it out and used it at infinite a few times.
I'm interested to hear your comments... I haven't used the lens much -the picture above is the first time I really used it, so I don't want to draw conclusions about image quality yet.
I thought the red dot variations were coated, non red dot are non coated.
The lily picture is shot as a paper negative... Does it seem soft compared to your expectations?
8x10 coverage Test @f/32
Seems good, haven't tried movements yet.
Next I will try f/9.

And to my eyes y'r non-test is soft all over. The lower right corner is especially soft. How's your eyesight?
A brick wall is a good suggestion, Dan.
Unfortunately the shutter on the goerz is not 100%.. No B or T mode. I'll have to work out a good way to find a wall the shoot it. Since I'm shooting paper at iso3, long exposures are difficult until I get the shutter fixed.
According to Goerz' specifications, the shortest Artar which covers 8x10 sharply at infinity is the 16 1/2".
