(c). Hold the eyepiece in place, rotate the adjusting ring slightly. 
To increase tension of  the eyepiece swivel, rotate the adjusting ring 
clockwise; to decrease the tension, rotate the adjusting ring counter-
clockwise.
2.2.4 Adjusting the Diopter
Before shooting, the diopter setting of  the viewfinder should be ad-
justed to the operator’s eye. To set the diopter (d) look through the 
viewfinder, rotate the diopter set ring until the edge of  the cross-
hair is at its sharpest point. It is...

To close the eyepiece shutter on the standard bellows eyepiece and 
250mm extension, grasp the ring at the base of  the eyecup and ro-
tate 1/8 of  a turn counterclockwise.On the hyperlong finder, rotate 
the knurled ring closest to the eyecup counter-clockwise to close the 
shutter.
2.2.6 Adjusting the Viewing Horizon
If  the rotation of  the image seen through the cameras viewfinder 
does not exactly match what is seen through the naked eye, there is 
a fine adjustment that can be made to the image’s...

2.2.8 Changing the Viewing Screen
The viewing screen is designed to be easily removed by the user 
for the purposes of  interchanging or for cleaning. To remove the 
screen, unscrew the black tool marked Vw located in the hollow at 
the rear of  the camera’s carrying handle. Remove the port cap. Clear 
the mirror shutter so that it is rotated safely inside the body by ro-
tating at the base of  the shutter with your finger or by setting the 
camera to test position, then removing the battery. Look into...

2.2.9 Adjusting the Viewing Screen
The image on the viewing screen should be sharp, and its focus 
should match to that of  the film. This can be best determined with 
the use of  a collimator, or by looking through the viewfinder and 
checking that the sharp focus of  a lens matches the measured dis-
tance on its barrel. If  it does not, then you need to make an adjust-
ment of  the viewing screen focus.
To proceed, you must first unscrew and remove the circular cap lo-
cated on behind the camera body...

operate Aatonite, power the body and switch the run/test switch to 
test position and off  again to turn on the camera electronics. Look 
through the viewfinder and rotate the jog to set the desired level 
of  illumination. The markings will remain illuminated for a full 2 
minutes after the camera is set in the off  position. The illumination 
level set in test position will be memorized and recalled once the 
camera is run. The illumination level can also be readjusted while 
the camera is running.

Make certain that the battery is off  the camera and remove the port 
cap. Locate the tool guiding hole to the lower right of  the inside of  
the lens holder (see diagram). Gently rotate the shutter at its base 
with your finger until the brass driving gear is centered underneath 
the tool guiding hole. Insert the shutter tool through the guiding 
hole and into the brass gear. Rotate the tool until the appropriate 
notched shutter setting is reached; turning counterclockwise will re-
duce the shutter...

2.4 FILM GATE AND PULLDOWN CLAW
2.4.1 Co-planar Movement
All Aaton cameras incorporate a patented means of  advancing the 
film called a co-planar claw movement. By utilizing this technique, 
Aaton is able to achieve an ultra-precise pulldown with a minimal 
number of  moving parts. The co-planar concept is the key to the 
camera’s low-noise operation.
The film gate also features a side pressure bar which is recessed into 
the claw-side rail at the point of  image exposure to assure maximum 
lateral...

cleaned every three to four mags if  the shooting schedule permits. 
Refer to the Cleaning chapter for more detailed information.
2.5 FLANGE FOCAL DISTANCE ADJUSTMENT
2.5.1 Concept
For a few years now, Aaton has inserted a spacer between the lens 
port and the camera body. This thin (0.3mm) metallic ring is re-
sponsible for the precise distance between the lens port seat and the 
film plane called the flange focal distance (FFD), and therefore it is 
also mainly responsible for the sharpness of  the...

lenses locking ring. Do not forget to unscrew two or three turns the 
locking ring stop, if  you have a PL lens port.
2.5.4 Adjusting the Viewing Screen
Because you have changed the distance separating the base of  the 
lens and the camera body, the image on your viewing screen might 
now appear to be less sharp than usual. Most likely, you may need to 
readjust the precise focus of  the viewing screen. Refer to the 2.2.9 
section of  this chapter to proceed.
2.5.5 Flange Focal Distances
Here are the...

yourself  towards the rear motor side of  the camera body. If  the 
aperture cover plate is on, remove it. Place your left hand around 
the front of  the camera just underneath the lens area. Grasp the 
magazine firmly with your right hand below the midway point of  its 
rear. While holding the camera body with your left hand, guide the 
magazine along the base of  the camera into the aperture area. Make 
sure that the top edge of  the throat of  the magazine is parallel to 
the carrying handle of...
