Does this exist?

A LF lens with 1 meter of coverage. It should but I can't find it.

There would be a diagonal of 1.25 meters(ish)

If you mean a 39" image circle, Goetz made artar process lenses at greater than 40" focal length. They will give you that at certain magnification. They made a 70" that will cover easily. Bet they're impossible to find.

Short answer, if you want to shoot at infinity, no. At portrait distances, yes. 70"/16 Apo Artar, 1780/14 and 1800/14 Apo Nikkors, 1800/16 Apo Ronar.

What's your application?

Before you do anything, learn to calculate and make sure of the coverage you need. The diagonal of a 1 meter square is 1.414 meters, not 1.25 meters. All of the lenses listed above will cover 1.25m or so at infinity, none will cover 1.4 meters at infinity.

Just wondering what would cover a 14x36 inch neg and the diagonal is actually less than 1 meter by just a hair. I figured 1.25 would give an small bit of wiggle room.

As for application I saw 14x36 inch x-ray film and wondered what lens might cover it.

No need to be a jerk dan. Question asks exactly what I was looking for.

The diagonal (linear measure) of the format covered depends on the angle the lens covers, the lens' focal length and the magnification.

For process lenses coverage (linear measure) is often quoted at 1:1; coverage (linear at measure) is half the coverage (linear measure) at 1:1. Simply telling us the size of your film (diagonal 705 mm) without telling us the magnification at which you intend to shoot doesn't give us enough information to answer your question responsibly. Off-the-top of the head answers are easy but won't help you.

Learn to calculate. Learn to be clear. Clarity requires understanding what you're doing. And don't insult people who try to enlighten you.

If you can find an ancient process/reproduction camera that made up to 48" copies. Good luck with that. We had a Deardorf 48"copy camera at the school I attended in the late 60's, it's been long since dismantled and gone.

If you have never built an ULF camera, I'd suggest starting with pinhole box camera. A lens would require a bellows, focusing mechanism, registered GG back, custom film holders, mechanism to align film plane to
Lens, etc.
