Two new convenient safety features have been added to the 645 PRO in the form of state-of-the-art optoelectronics which immediately identifies problems with the shutter (i.e. when it will not release) when the AE Prism Finder FE401 is used. Whether these malfunctions develop from failure to draw out the Dark Slide, or if there are problems in film take-up, the LED will indicate the source of the trouble.
Bright, Dynamic Images Visible on the Focusing Screen - 5 Selectable Types Available - Interchangeable Viewfinders 1. AE Prism Finder FE401 The AE (automatic exposure) Prism Finder FE401 features three modes of TTL metering, including automatic switching from center-weighted averaging to spot metering. It also has a +/-3EV exposure compensation adjustment.

Important: 1. The sealed, new battery which is supplied with this camera may have been subject to storage conditions which have reduced its service life. Therefore it is desirable to replace it with a fresh battery as soon as possible. 2. Carefully wipe the battery contacts before inserting into the chamber. Failure to do so may result in poor electrical contact and consequent malfunctioning of the camera. 3. Always remove battery when camera is not used for a while. Always carry spare batteries. 4.
When set to the yellow clock symbol 0 the self-timer is operative. See page 27 and 28 for further instructions. Operating the shutter Release Button For normal operation set the White Dot of the Shutter Release Selector (A) against the White Square Dot Cl. When set to the Red Dot 0, the Release Button is locked. 1. The Shutter Release Button @ functions in two steps. Gentle pressure will light the metering information display if the AE Prism Finder is used.
1. Attach the Roll Film Holder to the camera body. 2. Pull out the Dark Slide and place it into its Storage Slot. 3. Set the Shutter Speed Dial to any other position than ”A” or ”AEL”. When the AE Prism Finder is not mounted on the camera, the shutter will not release if the Shutter Speed Dial is in the “A” or “AEL” position. 4.

4. In the same manner, insert a roll of film in the upper compartment. At that time, check that the film leader paper is set as shown in the photo above. (The leader paper inside is facing outward on the pressure plate. Note that the film direction is wrong if the leader paper is facing inward.) 5. Pull out some of the leader paper. Insert the tip of the leader paper into the slot of the lower Take-up Spool.
Inserting the Roll Film Insert Film Speed (ISO) Dial Insert the loaded Roll Film Insert into the holder, the film roll on top, while squeezing on both sides of the Release Latch (A) as shown in illustration. Make sure that is been properly seated and is locked in place. Then close cover by firmly pressing its top against the Roll Film Holder. Each film holder has this important feature.
Color Codes Attach the loaded Roll Film Holder to the camera. Remove Dark Slide and store it. Turn the Multiple Exposure Lever (A) to its normal position, White Dot against White Square. Turn the Film Advance Crank until it stops. The number “1” will now appear in the Film Counter Window. The Focal Plane Shutter and Mirror are now cocked and the camera is ready for the first exposure. Set the desired shutter speed against the white index line (A) on the Shutter Speed Dial. 1.
4. “A and “AEL” explained “A (auto exposure) and “AEL” (auto exposure lock) setting must only be used when the AE Prism Finder is attached to camera. 1. If it is not attached and the dial is set to either of these positions, the shutter release will not work. 2. If it is not attached and the SelfTimer is activated, the Pilot Lamp will Iight for 10 seconds but the shutter will again not release. If the Shutter Speed Dial is set between click stops either the higher or lower exposure speed may result.
Set the desired f/stop on the Aperture Ring (A) by aligning the f/number with the red reference dot (B) in the center of the Scale Ring. The Aperture Ring has a click stop for each f/ stop. In-between clicks can also be used. The effect the set f/stop will have upon the picture area can be confirmed on the Finder Screen. Move the AM Lever on the lens so that “M” becomes visible - the lens then can be stopped down to the preselected aperture.
Focusing with the Standard Focusing Screen N Type E While looking through the viewfinder, turn the lens Focusing Ring until the most important subject part appears sharp and clear. 1. The camera comes equipped with a bright, Type E, RangefinderlMicro-prism Focusing Screen. It features a center, split-image rangefinder spot and the subject is in sharp focus when the split images combine into one. 2. The microprism ring around the split-image center further facilitates focusing.
Reading the Depth of Field Scale Depth of field is defined as the zone of sharpness before and behind the plane of focus. It depends on camera subject/distance, focal length of lens, aperture setting and distance the lens is focused at. In addition to visual observation, the Depth of Field can be determined by using the Depth of Field Scale on each lens. f/stop numbers appear on both the right and left side of the red index mark in the center of the scale ring.
* Move the empty spool from the top to the lower (take-up) compartment, ready for loading the next film roll. * Never load, unload or handle film in direct sunlight. 1. Giving the Film Advance Crank one complete turn, will cock the shutter and mirror and ready the camera for the next exposure. 2. When the film is completely exposed (15 exposures on 120, 30 on 220 film), the crank stop will disengage. Continue turning until the paper trailer is completely wound onto the take-up spool.
To use the Self-Timer, set the Shutter Release Selector to 0 and press the Shutter Release Button. The Battery Check Lamp will light for 8 seconds and blink for 2 seconds, whereupon the shutter will go off. * After using the self-timer mode, be sure to return the Shutter Release Selector to the White Square. (Normal mode.) + To override the self-timer, after having pressed the release, move the selector back to the white square.
* To override the multiple exposure mode or to return to normal operation, be sure to return the lever’s White Dot against the white squareandthenadvancethefilm. (If you forget you will continue to make multiple exposures on the same frame.) will stay open until the shutter release is pressed again. You may also use a cable release together with the cable release adapter. (The battery circuit will automatically switch off to save power.
This is an important feature when the tripod mounted camera is used at slow or long exposure times and particularly also with use of long telephoto lenses. It eliminates the possibility of even the slightest “mirror bounce ”which may affect image sharpness. Move the Mirror-up Lever to the yellow "M.UP" square, after you have composed and focused your picture. This will raise the mirror and the viewfinder image will be blacked out. After use, return lever to normal (white square) position.
Infrared light rays - being of longer wavelength - focus at a slightly different plane and require the following adjustment: 1. Note the Red Index Mark against which you read your distance scale. The red infrared index mark is slightly to its right. 2. After focusing in the usual manner, read the distance scale and move it to the right to line up with the infrared index mark. * For proper filter and exposure information be sure to consult the instructions enclosed with infrared film. * The A300mm f/2.
When using the Hot-shoe, be sure to put an appropriate Safety Cover over the Xsync terminal so that you won’t receive a high voltage electric shock if the terminal is accidentally touched. (A Safety Cover is put on the Xsync terminal when the camera leaves the factory.) 1. When using an electronic flash, plug the synchronization cord into the Sync Terminal and set the Shutter Speed Dial to 1/60 sec. or slower. * The Mamiya 645 PRO has an Xsync terminal.
2. For MF and M bulbs, set the Shutter Speed Dial to 1/30 sec. or slower for the MF type, and 1/15 sec. or slower for the M type. * When using a flash, carefully read the instructions that come with the flash bulbs or flash unit to check for appropriate shutter speeds and to avoid malfunctions. The Mamiya 645 PRO Tripod Socket accepts a standard 1/4" tripod mounting screw.
