CAMERA WITH IRIS TYPE LENS MOUNT

With a ground glass plate at the hidden end this object is almost certainly a camera. However the lens shown is not the original.
This object will be accessioned shortly as we now believe it to be a camera with an Iris for mounting a variety of lens's as suggested.
If anyone recognises it please let us know.

Your comments:

  • I think this is an artist's aid. It would produce an inverted image of a brightly lit scene which could be used to help an artist with the perspective.

  • This "large iris" was a normal way to permit easy and quick lens changing. It has the great advantage that it can hold lenses of any diameter and does not rely on matched threads! I have used a couple of cameras with this type of mount and it is surprisingly rigid and light tight.
