Camera and reversed lens.
This is an interesting lens. It's a 30mm F4 fixed aperture and
focus free Xenagon lens. It's a "spy" lens, they called it
"Beamten-Objektiv" (civil servant lens). It focusses from about 2m to
infinity. The edges are soft. As it has a 26mm thread on both sides,
the lens can be reversed. In reverse mount it focusses from about 70cm
to 3m. With this lens, a 50 exposure wind camera and a cable release the
camera could easily be hidden for spying purposes. These lenses have no markings, no manufacturer sign and no serial number.

This
lens is much lighter than the old version (124/216 gr). There are some
more differences. This one has a 5-blade aperture, the old version is
multi-blade, perfectly round. The new version focuses down to 37cm at
F8 (old: 55 cm at F 8). Mine has faint click stops for the aperture and it
has no firm grip to unscrew. It moves more easily, settings are easier
to read. So both versions have their pros and cons. According to the serial number, this lens was made in 1978.
