AE Prism Finder RZ
English Instructions
Special Features
1. The finder uses a roof prism to produce an unreversed, laterally correct and bright
image, with quartz-controlled, aperture-priority automation to calculate exposures.
2.
The viewfinder’s LEDs display the metering mode and shutter speed.
3. In AE Mode, perfect exposures are now possible after merely focusing the camera
and releasing the shutter.
4. A metered-manual mode is also provided for match-LED operation or exposure
compensation.
5. You can select from three Metering Modes: Spot, Averaged and Auto-Shift. Auto-Shift
automatically changes from Averaged to Spot Metering Modes, or vice versa,
depending on the lighting conditions.
6. There are three options for exposure compensatio: AE Lock, the Exposure
Compensation Dial and metered-manual operation.

stop intervals. Manual Mode: 8 sec. to 1/400 sec. in
½ stop intervals.
Viewfinder Readout
Metering Modes are indicated by ‘A’ (Averaged) or
‘S’ (Spot). Shutter speeds of 1 sec. to 1/400 sec.
and ‘LT’ (>1 sec. to 4 sec.) are displayed. Flashing
LEDs indicate overexposure (∆), underexposure
(LT) and a weak battery. In Metered Manual Mode,
the preselected shutter speed is illuminated and the
appropriate shutter speed flashing.
Metering Range
EV 1 to 18.5 (f/2.8 at 4 sec. to f/32 at 1/400 sec. -
ISO 100 and 110mm f/2.8 lens
Exposure Compensation ±3 EV in 1/3 click-stop intervals.
AE Lock
The exposure will be memorized when the finder’s
Shutter Speed Dial is set to ‘AEL’ and the camera’s
Shutter Speed Dial is depressed halfway.

Attaching the Finder to the Camera Body
1. Remove the Waist Level Finder from the camera body.
2. Remove the plastic Electrical Contacts Cover (if installed), Fig. 1, by pulling it up and off the
camera’s Electrical Contacts (10).
3. Insert the finder’s two Attaching Pins into the camera’s finder mounting holes.
4. While pushing the finder’s two Attaching Latches (8) down and toward the back of the finder,
lower the finder onto the camera body, gently push it down until it seats with the camera body,
and then release the two Attaching Latches (8), Fig. 2.
5. Gently lift up on the finder to verify that it is securely latched to the camera body.
Removing the Finder from the Camera Body
1. While pushing the finder’s two Attaching Latches (8) down and toward the back of the finder, lift
the front of the finder up.
2. Pull the finder’s two Attaching Pins out of the camera body’s finder mounting holes, and then
remove the finder from the camera body, Fig. 2.
How to Use the Finder
1. Depress the camera’s Shutter Speed Dial Lock Button and turn the Shutter Speed Dial so that it
is at the position between ‘B’ and 400; this is the AE position, Fig. 3.
If the Shutter Speed Dial is set to any other position, the finder will not be able to couple with the
camera body and AE photography will not be possible.
2. Align the ‘A’ on the finder’s Shutter Speed Dial with the white Index Mark on the finder, Fig. 4.
The Dial will lock at this position.
3. Set the film’s ISO speed on the Roll Film Holder’s ISO Dial.
4. Use the finder’s Metering Mode Selector and set the desired Metering Mode, Fig. 4.
The Averaged ‘A’ Metering Mode uses information from the entire frame to determine
exposures.
The Spot ‘S’ Metering Mode only uses information from the central area of the frame to
determine exposures.
The Auto-Shift Mode will automatically switch between Averaged and Spot Metering Modes
depending on the lighting conditions.
5. Select an aperture, and then depress the camera’s Shutter Speed Dial down halfway. The finder’s
LED’s will indicate the Metering Mode (‘A’ or ‘S’) and the correct shutter speed for the selected
aperture.
If ‘LT’ illuminates, it indicates that the exposure is correct for >1 sec. but ≤ 4 sec.
An blinking triangle (∆) (8 times/sec.) indicates an overexposure.
An blinking ‘LT’ (8 times/sec.) indicates an underexposure.
In Auto-Shift Mode, either ‘A’ or ‘S’ will illuminate to indicate which of the two modes is being
used. If both ‘A’ and ‘S’ are illuminated, the area measured by the Spot Metering System is
0.75 – 1.5 EV (3/4 to 1 ½ stops) darker than that measured by the Averaged Metering
System.
A weak battery is indicated when any of the of the shutter speed LEDs flash about 2
times/sec.
When looking through the finder, the position of the Camera Monitoring LEDs will appear
reversed.
Tips for Selecting a Metering Mode
1. When your subject is backlit against a bright window, sky or snow scape, using Averaged
Metering Mode may result in an underexposure. Spot Metering Mode will eliminate the adverse
backlit influence and result in a more accurate exposure.
2. Use Averaged Metering Mode to create backlit silhouettes; use Spot Metering Mode to highlight
your subject.
3. In Auto-Shift Mode, if the area read by Spot Metering is more than 1½ stops darker than the area
read by Averaged Metering, Spot Metering Mode is automatically selected.
4. When the area read by Spot Metering is approximately the same, or brighter, than that read by
Averaged Metering, Averaged Metering Mode is automatically selected.
5. When the area read by Spot Metering is ¾ to 1½ stops darker than that read by Averaged
Metering, the finder will automatically select an intermediate exposure value, picking the
equivalent of center-weighted reading. In this case, both ‘A’ and ‘S’ will be illuminated in the
viewfinder.
6. For the highest degree of accuracy when working under difficult lighting conditions, use Spot
Metering Mode and AE Lock.
7. When using a remote control unit, close the Eyepiece Shutter to prevent stray light from entering
the eyepiece and affecting the exposure reading.
Exposure Compensation
The finder’s automatic exposure settings are accurate for most subjects; however, for unusual lighting or
special effects, the following two methods may be used:
AE Lock is very useful for making selective exposure measurements that are not in the center of the
frame.
Although it can be used with any Metering Mode, it is most effective when used with the ‘SP’ (Spot)
Metering Mode.
AE Lock Photography
1. Set the finder’s Shutter Speed Dial to its ‘AEL’ position. Fig. 5.
2. While looking through the finder, center the most important area of the subject in the center
circle of the frame, and then press the camera’s Shutter Release Button down halfway and keep
it in this position. The exposure will be memorized.
3. While keeping the Shutter Release Button down halfway, adjust the composition, and then push
the Shutter Release Button down all the way to fire the shutter.
Wait for the shutter speed to be displayed in the viewfinder before firing the shutter.
AEL Photography cannot be used with remote control units.
Exposure Compensation Dial
1. Depress the Exposure Compensation Dial’s Lock Release Button and turn the Dial to adjust
exposure, Fig. 6.
Exposure compensations up to ±3 EV may be applied in 1/3 EV steps.
Turning the Dial in the + (clockwise) direction increases exposure; turning it in the –
(counterclockwise) direction decreases exposure.
The Prism’s Viewfinder
Metered Manual Exposure
1. Set the camera’s Shutter Speed Dial to its AE position, Fig. 3.
2. Turn the finder’s Shutter Speed Dial to any shutter speed.
3. Use the Metering Mode Selector, Fig. 4, and select a Metering Mode.
4. Press the camera’s Shutter Speed dial down halfway. The Metering Mode and the selected shutter
speed will be displayed in the viewfinder, and the shutter speed that the finder deems
appropriate will flash at 4 times/sec.
5. Use Manual-Zero Mode to determine the correct exposure:
You can change either the shutter speed or the aperture to obtain a correct exposure.
When changing the aperture, turn the Aperture Ring until only one shutter speed is displayed
in the viewfinder.
When changing the shutter speed, turn the finder’s Shutter Speed Dial until only one shutter
speed is displayed in the viewfinder.
Diopter Correction Lenses
The viewfinder is factory set for people with average eyesight.
If you are farsighted or nearsighted, and do not want to wear corrective lenses when photographing,
install a Diopter Correction Lens on the finder.
If you are farsighted, correction lenses are available in: +3, +1 and +1 diopters; if you are nearsighted,
correction lenses are available in: -0.5, -1, -2, -3 and -4 diopters.
Installing a Diopter Corrective Lens on the Finder
1. Remove the finder’s rubber Eyecup.
2. Insert the top of the Corrective Lens into the top of the finder’s Eyecup Frame, and then push the
Lens down into the frame until it snaps into place, Fig. 7.
3. Reinstall the Eyecup.
Removing a Diopter Corrective Lens from the Finder
1. Remove the finder’s rubber Eyecup.
2. Insert your fingernail between the bottom of the Corrective Lens and the bottom of the finder’s
Eyecup Frame.
3. Pull the Corrective Lens out of the frame.
4. Reinstall the Eyecup.
