Mamiya-Sekor EF/E Lenses
<<<< Additional information not in the manual:
I just wanted to point out that not all Mamiya M42 lenses are safe to use with the P adapter for the Auto-XTL. If
you attempt to use the SX type lenses with the Auto-XTL P adapter, the aperture sensing pin will dig into the P
adapter face since it is not perfectly flush with the outer surface edge of the SX lense. Furthermore, since the
entire moving surface of the aperture ring of the SX lense comes to rest against the P adapter face, it will lock
down the aperture control of the lense and make it impossible to turn, therefore preventing SX lens f-stop
manipulation. Mamiya M42 AUTO lenses seem to be safe choices as are M42 Yashica-Yashinon, M42 Meyer-
Optik and M42 Zeiss MC Sonnar (S) lenses. Any aperture ring that rotates at the extremity of a lens should be
avoided. Of course the SX lens works perfectly well with the "ZE" P adapter for Mamiya ZE series lenses
which it was designed for. Lenses with Auto and Manual switches like Zeiss MC Sonnar work well with the
Auto-XTL P adapter in conjunction with its Auto Aperture pin. Lenses that have no Auto Aperture and only
manual control of aperture appear to work equally well like Meyer-Optik Orestor M42.

Mamiyalite MZ 36R
This grip-type automatic electronic flash unit takes full advantage of the ZE-
X's crossover mode feature and sophisticated electronic aperture control
systems for flash photos with unprecedented ease and accuracy. The MZ 36R
has a guide number of 36 (ASA 100 in meters) which is reduced to 28 when
the wide angle diffuser is used.
The head of unit can be swung upward 90 and rotated almost one full turn,
besides, the flash sensor is removable and may be attached directly to the
camera hotshoe to permit bounce flash operation on auto. Used with the ZE-X,
it automatically synchronizes for flash at 1/60 second on charging and used
with EF lenses automatically selects the aperture to obtain proper exposure in
relation to film speed and focusing distance.
