On my 6x9 folding camera it has a Schneider-Kreuznach f/4.5 105mm lens. The distance scale goes like this; 1, 1.2, 1.5, 2, 2.4, 3, 4, 6, 12, and infinity. Are these numbers in meters or feet?

Thanks in advance for your help.

The OP seems to have signed off. The lens is a Radionar,

sounds like feet.
Set it to 3 and look through the viewfinder.
Is the focus at 3 feet or 3 meters?

That is the problem. If does not have a rangefinder type of viewfinder.

My first adjustable camera was a Baldalux with the same lens, bought used in 1958. Dropped it down the cellar steps a couple of years later. Unfortunately, I no longer have any negatives or prints taken with it. The negatives were very sharp. Hope it will be useable.

Edit: The distance scale is indeed in meters.

You will just have to try it out to see if that "Mtr." means what it says.

My lens does not have "Mtr" marked on it.

Thanks for all the replies.

No lenses in that era could focus down to one foot. The parallax issues are too severe for that although it sounds to me like your camera focuses on a ground glass. Secondly this is a German lens and as you probably know Germany and every other country in Europe except England uses the metric system. The exception to that caveat were some of the Kodak cameras such as the Retina series which had Schneider Xenar lenses made in Kreutznach, Germany and those have both feet and meters on the lens barrel. I am a camera collector and have a Kodak Retina with a Xenar lens and it can focus only down to 3 feet which is typical of cameras of that era (1950's).

The distance scale on the lens in the picture says Mtr just after the infinity mark. That means the numbers are in metres.

If you're not familiar with metres, they're like a yard with about an extra three inches on the end.

Yes.. meters....
And if the scale were feet, the last number before infinity would typically be 30, as in 30 ft.
