Anyone having a bit more info on that lens? It seems to be diffraction limited from measurements we took on an optical bench with a friend and the results are outstanding.
The max. error that lens produces is given in literature as plus/minus 4 micron over the full covered field. Coverage is mentioned to be 4x5" (102x127mm). It was part of the WILD metric camera system P31, has an integral built in shutter (Hasselblad-like) has variable aperture f/8-22, bajonet lock UV filter (400nm) and a matching rectangular sunshade. It has been mounted professionally on a lensboard (Sinar?).
I have it sitting around unused, so any proposals for its use or more info about it out there?
The lens looks like the one on top left of this picture:
