Guy, I think it is nothing but a regular 50mm lens to which a pinhole has been added, probably inside the lens itself and in between the front and rear elements, by leaving a good portion of the lens uncovered you are assured to be able to frame the shot using the viewfinder, then you close the aperture until it covers the round black portion on which the pinhole is made or mounted and make the exposure. This lens will provide enormous DOF at expenses of diffraction. Not a pinhole lens in the sense we use them, but a trick many model builders (trains, ships, etc) utilize to make images of their creations and get a DOF that is close to what they would get if the subject was life size.
