What is the longest lens for 8x10

[tbirke]

Hi everyone,

I just wonder what is the longest lens for 8x10 available?
Longest I heard of is the Nikkor 1200 f18.
The longest available through known online dealers seems to be the Schneider 1100mm f22.

Any additions?

I think the longest is the Apo Ronar 1760mm or somwhere around thad!

Or the comparable Goerz 70" Apo-Artar.

What's the image circle on that, Robert?

A quote from Astrophotograhy:

"The focal surface can be much larger than any currently available solid-state detector. For example, the generation of 4-meters telescopes that were built in the 1970s and designed for traditional photography had fields of one degree (the full moon is a about half a degree), which were recorded on photographic plates 250 millimeters (10 inches) square."

So, an 8x10 wouldn't be so out of place here after all...

Will it fit on my 6" square lensboard? What kind of tripod head do I need? How do I get my wife to carry THAT one?

Thanks, Robert!

I have the Nikkor 1200. It is a T lens (telephoto) which makes it able to focus at infinity at about 32 inches (rough guess).

It's the equivalent of a 200mm on a 35mm camera and does quite a job of flattening out the scene. I have the 600mm as well as they are changeable back sides of the T lens. I love both of them and wish I could find and afford the 800mm that completes the set. The F stop guide on the front element (copal 3) has f stop guides for each lens. I believe my Canham 8x10 has about 36" of bellows.

There are of course the other mentioned longer lenses, probably once used as process lenses, but one would be limited by the bellows length and probably droop.

The longest lens I have for my 12x20 is a 35" artar. My bellows on that camera are 48"

I think you mount the camera on this lens, rather than vice versa... As for you wife, you can promise her the moon and stars!
