Inserting a Battery -~ The Mamiya M645 uses one 6V silver oxide battery 4SR44 (Eveready No 544, UCAR 544, Mallory PX28 or equivalent or alkaline battery 4LR44 1. Pull the battery chamber cover latch (26) slightly toward the lens and the chamber cover will open 2.
Battery Check -..--- This camera is designed for use with either silver oxide or alkaline batteries. Although both types offer adequate performance, silver oxide batteries last much longer IMPORTANT.
Film Loading - ____-----.-- 0 Loading the Film 1 . While gently pushing in on the memo clip (19), move the back cover latch (17) in the direction of the arrow and the camera back cover will open. 2. While squeezing in on both sides of the release latch (37) pull the roll-film insert out of the camera body.
4 . In the same manner insert a roll of film in the upper compartment. 5 . Make sure that the black side of the leader paper faces up. 6 . Gently pull out some of the leader paper, pulling it over and around the pressure plate. Then insert the tip of the leader paper into the slot of the take-up spool.
* Never load film in direct sunlight. Load it in the shade or in your own shadow. * Roll-film inserts for both 120 and 220 film are loaded in the same manner. The exposure counter advances to 15 when the 120 film insert is used, and to 30 when the 220 film insert is used.
0 Insertion of the Film Insert 1. Grasp both sides of the release latch (37) of the film insert, making sure that the film type index (42) is not upside down, and place the film insert straight into the camera body. After the film insert has completely entered the camera body, let go of the release latch.
1. After the film has been placed into the camera make sure that the multiple- exposure lever (25) is aligned with the white dot and not with the word “MULTI”. 2. Wind the film advance crank until it stops and the number 1 will appear in the exposure counter window (20).
Aperture Ring/Stop-down Operation -- (c)The red B represents BULB. The shutter will remain open as long as the shutter release button is depressed when the shutter speed dial is set to B. (d)The red 60X represents the highest permissible shutter speed for electronic flash synchronization.
Focusing 1 . While looking through the viewfinder, adjust the focusing ring (30) until the most important part of the subject ap- pears sharp. 2. Extremely accurate focusing is sim- plified by the split-image rangefinder spot located in the center of the focus- ing screen.

The PD Prism Finder is an eye- level finder with a built-in silicon photo diode exposure meter and electronic shutter control circuit. 2. The PD Prism Finder offers complete coupling of the lens aper- ture, shutter speed, and film speed (ASA) 3.
2. Attach the PD Prism Finder to the camera body. 3. Turn the aperture ring of the lens so that the exposure meter coupler (35) of the lens and the aperture ring coupling pin (A) of the PD Finder engage.

0 Exposure Compensation The LED Panel incorporated into the PD Prism Finder simplifies exposure com- pensation, assuring perfect exposures everytime. Each LED represents a full stop increment and plus and minus signs are indicated within the view- finder to assist in compensating.
a Inserting the Battery ------ i 0 Special Features 1. The CdS Prism Finder is an eye-level finder with a built-in CdS exposure meter for accurate exposure measurement.
1. Remove the battery chamber cover by rotating it counterclockwrse with the aid of a coin. 2. The underside of the battery cham- ber cover bears a + mark. Be sure to have the + marks of battery and cham- ber cover face each other as the bat- tery is inserted.
Using the CdS Prism Finder (2) ..- . 3. Set the meter of the CdS Prism Find- er to the correct ASA . To do so, pull out and rotate the ASA dial (B) so that the appropriate ASA number appears in the window, aligned with the index mark. 4. Turn the exposure meter switch to ON.
If the indicator needle cannot be cen- tered even after rotating the aperture ring as far as it will go, the exposure must be adjusted by rotating the CdS Prism Finder shutter speed dial. If the indicator needle is too high, set the shutter speed dial to a shorter (“faster”) speed; it too low, set to a longer (“slower”) speed.

Depth-of-field refers to the total area (foreground and background) which will appear in focus (sharp). The area of sharpness (depth-of-field) depends upon the distance the lens is focused at, the f/stop (or aperture) being used, and the focal length of the lens.
Using Flash _‘ ’ ~---- __.-- _ , Precaution when Using Flash When using the X-sync terminal of the camera body, be sure to insert the plastic safety cover into the hot-shoe, and when using the hot-shoe, be sure to insert the appropriate safety cover into the X-sync terminal.
When the white dot of the multiple-exposure lever (25) is aligned with MULTI, the double-exposure prevention mechanism is disengaged, so that the shutter can be cocked with the film advance crank without moving the film, making multiple-exposures possible.
Mirror Lock-up .- -.-- When the camera is mounted on a tripod for copy work or telephotography at long (slow) shutter speeds, the small amount of vibrations due to”mirror-bounce”, which normally are of no consequence, may cause blurring of the image due to the high magnification encountered in extreme close-ups and telephotography.
Using the Delayed S Shutter Release ..~.. Attach the camera to a tripod or place it on a firm support. (If the camera sup- port protrudes beyond the front of the camera body, cock the delayed shutter release before placing it on the sup- port). 1. Advance the film and cock the shut- ter with the film advance crank 2.
Interchanging the Film Advance Crank with the Shutter release button, by- passing the delayed shutter release, as often as desired * If the delayed shutter release is in- advertently started when the shutter is uncocked, it will stop after partially functioning.
The film advance crank is interchangeable with the film advance‘knob which is available as‘ an optional accessory. 0 Attaching the knob 1. Rotate the film advance knob recep- tor of the camera body clockwise as far as it will go (the red dot (B) will then be facing upward).
Tripod Socket ---- - ___--~ Time Exposures __-- _- - __ - As a general rule of thumb for optimum sharpness, we recommend using 1/125 sec. as the minimum shutter speed for hand-held shooting. For longer exposures (1/60 sec. - 8 sec.), attach the camera to a sturdy tripod.
Trouble-Shooting If your camera appears to be malfunctioning, check the list below to see whether or not you have forgotten some- thing. 1. The shutter release button will not move. A) Did you unlock the shutter release button? (p.30) B) Did you wind the film advance crank until it stops?(p.
Precautions Releasing the shutter with no film in the camera The film transport mechanism has a built-in safety lock which prevents the shutter from being released after the last exposure on a roll of film, or when there is no film in the camera.
Care of the Camera Cleaning When the camera is not used for a long period of time, remove the battery and any film from the Never touch the lens or mirror surfaces. Keeping a camera. Do not store the camera at temperatures exceeding 100rF (4O’C). or at temperatures less than 15-F (-10%).
