1 PD Prism Finder English Instructions

2 Special Features 1. The finder produces an unreversed, laterally correct and bright image, has a built-in Silicon Diode metering system and an eyepiece that is raised 30 for ease of viewing. 2. When the finder is attached to a camera body, the aperture, film speed and shutter are coupled between the camera and the finder. 3. Instant switching from Average Exposure Mode to Spot Metering Mode is accomplished via the finder s Dual Metering Switch. 4. The viewfinder s display uses green, red and orange LEDs to indicate a correct exposure, an overexposure, an underexposure and the selected Metering Mode.

Remove the plastic Electrical Contacts Cover (if installed), Fig. 1, by pulling it up and off the camera s Electrical Contacts (10).

3 3. Insert the finder s two Attaching Pins into the camera s finder mounting holes. 4. While pushing the finder s two Attaching Latches down and toward the back of the finder, lower the finder onto the camera body until it seats with the camera body, and then release the two Attaching Latches, Fig 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 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. Set the film s ISO speed on the Roll Film Holder s ISO Dial. 2. Use the finder s Dual Mode Selector to choose either the Average Metering Mode, A, or the Spot Metering Mode S, Fig. 3.

4 Average Metering Mode uses information from the entire frame to determine exposures. Spot Metering Mode uses only the information from the central area of the frame to determine exposures. 3. Press the finder s Power Switch, Fig. 3 to activate its metering circuit. After pressing the Power Switch, the circuit will remain active for about 15 seconds, and then automatically turn off. 4. While the metering circuit is active, turn either the Aperture Ring or the camera s Shutter Speed Selector until the viewfinder displays a green LED on the right-hand side. The correct exposure is now set. If the meter s circuit is no longer active, press the finder s Power Button to reactivate it. Viewfinder Display Metering Mode The letters A (Averaged) and S (Spot) indicate which Metering Mode is being used. Correct Exposure The viewfinder displays a GREEN LED. Overexposure More than 1 Stop The viewfinder displays a RED PLUS SIGN. Overexposure Less than 1 Stop The viewfinder displays an INVERTED ORANGE TRIAGLE. Underexposure More than 1 Stop The viewfinder displays a RED NEGATIVE SIGN. Underexposure Less than 1 Stop The viewfinder displays an ORANGE TRIANGLE. o Note: When looking through the viewfinder, the camera s Monitor LEDs will appear to be 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. For the highest degree of accuracy when working under difficult lighting conditions, use Spot Metering Mode.

5 Exposure Compensation Because exposure readings are made through the lens (TTL), no exposure compensation is necessary when using filters, extension tubes, a bellows, etc. When using extension tubes at large magnifications, focus the lens BEFORE determining the exposure. To prevent extraneous light from entering the finder and affecting the accuracy of the exposure calculations, keep your eye close to the viewfinder when photographing. Precautions If the finder s Power Switch is pressed when the camera s Shutter Speed Dial is set to B (Bulb), the viewfinder s RED PLUS SIGN (+) will illuminate and it will not be possible to obtain a correct exposure. Be sure to keep the electrical contacts on the camera and the finder free of contaminates. If necessary, clean the contacts with a soft, dry, lint-free cloth. When storing the camera with the finder attached to the camera body, make sure that other pieces of equipment cannot accidentally press the finder s Power Switch. The finder is not applicable to the RB67 series of cameras. The finder cannot indicate correct exposures when the Type D Focusing Screen is installed on the camera body. 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 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.

6 3. Pull the Corrective Lens out of the frame. 4. Reinstall the Eyecup.
