Not connected to me.

Vendor says that this is suitable for m4/3. It does not look like one of the Heligon type of TV projector lenses which suffer from terrible distortion as they are not designed for visible light wavelengths. Will need a helicoid.

Buyer beware!

Completely misinformation. It is a cheap old X-ray lens, has no aperture and the back focal length is just fractions of an inch. Only good for very close macro shots (ca 200mm max from lens front). But they were made for visible light (usually blue or green only depending on phosphorus used)

Thanks Klaus!

I am aware of those lenses, but this one fooled me because the diameter at light exit was so narrow it looked like a cine lens. Thanks for the correction.
