2.1.3 Aaton Lens Port
The XTRprod can also be equipped with an Aaton lens port. In or-
der to install the Aaton port, the ArriPL lens seat and locking ring
must first be removed.
Because the FFD of the Aaton lens port is shorter than most profes-
sional cameras (40mm), the XTRprod, equipped with this mount,
can accommodate most motion picture and still camera lens
mounts. Lenses can be used equipped with an Aaton mount or by
adapting another manufacturer’s lens mount. Aaton lens adaptors
are available for Arri standard, Arri bayonet, as well as Nikon and
Leica-R photographic mounts.

THE CAMERA BODY
The Pechan prism
In order to provide a fully
orientable upright image, the
Aaton viewfinder incorporates
a pechan prism assembly, whi-
ch is actually comprised of two
triangular prisms sandwiched
together. On some viewfinders,
depending on the construction
of this prism, rotation of the
eyepiece a full 360° will cause
the image in the finder to shift
slightly left or right.
After attaching an extension
finder, if the image in the fin-
der appears to have shifted
slightly, rotate the finder 360°
and choose the preferred cente-
red image.
