Lift the battery case lock lever, turn it counter clockwise and pull out the battery holder. The batteries are sufficiently charged.
Diopter Adjustment Look through the viewfinder and make sure that the focus frame (Rectangle with Circle) is in sharp focus. If it is not, turn the diopter adjustment dial in the "-" direction if you are nearsighted, in the "+" direction if you are farsighted. If this is not sufficient you may require an optional diopter corrected lens. See below. Replacing the diopter corrected lens 1. Remove the lens supplied with the finder by pulling it downward. 2.
Attaching/Removing the Lens Removing Attaching 1. Remove the camera's lens opening cap, just like you would remove a lens, by pushing the lens release button “A” backward and then turn the lens cap or the lens itself counter clockwise and lift out. To remove the front lens cap, squeeze the shiny sections together and lift out. While pushing the lens release button “A”, rotate the lens counter clockwise until it stops and lift it off.
Installing the Battery in the Magazine The button battery supplies power to the magazine's LCD when it is detached from the camera. When it is attached the power is supplied by the camera's batteries. 1. Remove the battery compartment cover screw. Setting the Film Speed The film speed (ISO sensitivity value) is the reference for all exposure and must be set correctly. If the set value differs from the actual value of the film in use, under- or overexposure may occur. 1. Press the ▲ (up) button.
Attaching/Detaching the Magazine When there are no batteries in the camera, the shutter's "Safety Retraction" feature, keeps it in the open position and the magazine's dark slide cannot be pulled out, even when it is attached to the camera. Film winding and shutter release are also blocked in this case. Detaching 1. Insert the dark slide into the magazine. Attaching 1. Remove the camera's rear body cap and the magazine's protection cap. 2.
Loading Film in the Magazine 1. Open the back cover of the magazine. By first pushing the button “A” down and then button “B” simultaneously. 2. Take out the roll-film insert. Squeeze the center block "645" “C” between your fingers and pull it out. • When you load film for the first time, remove and discard the protective paper cover which is attached to the film rails in the magazine. 4. Attach an empty spool to the roll-film insert.
Shutter Release Button/Holding the Camera 7. Insert the loaded film insert into the magazine. While squeezing the center latches together, place the film insert, with the feed spool on top, in the magazine and with pressure on the left and right blocks “G” push it into proper position. (You will hear a click). Shutter Release Button The shutter release button has a two-step action, A half-press (light pressure) will activate the camera, heavier pressure will release the shutter.
Taking Photos in the Full Automatic Mode 1. Set the shutter release mode selector lever to "S" (single-frame advance mode). There are two shutter release modes: "S" (singleframe advance mode) and "C" (continuous advance mode). (See page 47.) When set to "L", the power is turned off. 3. Set the exposure mode selector dial to "P" (program auto exposure). There are four exposure modes: "P" (program AE), "Av" (aperture priority AE), "Tv" (shutter priority AE) and "M" (manual mode). 2.
6. Unloading the exposed film. 5. Focus. 1. Aim the camera so that the subject is within the focus frame When the fixed number of exposures have been taken, the camera automatically takes up the film till the end and stops. The LCD panel on the magazine should display End now. 1. Open the back cover. While holding down the magazine's back cover lock release button “A” push the back cover release button “B” to open the back cover. 2. Remove the roll-film insert.
Removing a partially exposed film roll To remove partially exposed film roll, insert the dark slide in the magazine and press the shutter button and the forced film advance button “A” simultaneously. This causes the film to be taken up till the end and the magazine's LCD panel shows "End". 6-exposure film If you continue photographing after the 8th exposure when using 6-exposure film, the shutter membrane may be damaged by the leader paper at the film end or by the film's sticker.
Single Focus Mode (S) Manual Focus Mode (M) The auto focus function can be turned off so the focus can be adjusted manually. This mode uses the focus priority mechanism. The shutter can be released when the focus mark in the viewfinder is lit. This mode is suited for still subjects. The focus is locked when the ● focus mark lights in the viewfinder's LCD. 1. Set the focus mode selector lever to "M" (manual focus mode). Turn the focus mode selector lever to "M" (manual focus mode). “M.F.
Manual focusing using the focus mark. (Focus confirmation method) With this camera, a focus mark ● lights in the viewfinder's LCD when the picture is in focus. With the shutter release button half-pressed, turn the lens focusing ring to focus on the subject. When the subject is in focus, the ● focus mark lights in the viewfinder's LCD. Subjects With Which Auto Focusing May Not Work The auto focus function requires subject contrast.
Using the Focus Lock Function If the object on which you want to focus is not in the focus frame, the camera focuses on the background at the middle. In such cases use the focus lock mechanism to lock the focus before taking the picture. 1. Set the focus mode selector lever to "S".
Camera Operation Test This is a simple way to test the camera and autofocus without film. "P" Mode is the easiest. You may use any mode but "T". 1. Set the shutter release mode selector lever to "S" (to turn the power on). 2. Remove the Dark Slide from the magazine. 37 3. Open the back cover. 4. Set the autofocus modeselector lever to "S". 5. Release the shutter.
Program AE (P) Aperture Priority AE The aperture and shutter speed are determined automatically for the optimum exposure, according to the existing ambient light. This mode is best suited for general photography, allowing the user freedom to concentrate on the subject. Set the desired aperture and the camera selects the optimum shutter speed accordingly. Use the Av mode to maintain specific control over depth of field, i.e. taking portraits or landscapes.
Manual Mode (M) Shutter Priority AE Set the desired shutter speed and the camera selects the optimum aperture accordingly. Use the Tv mode to maintain specific control over action, i.e. shooting sporting events or deliberately blurring your subject. Use the manual mode "M" when you desire to have complete control over shutter speed and aperture settings. This mode is also best utilized in combination with an independent hand-held exposure meter. 1.
*If the difference between the manual setting and the metered value is greater than 6 EV, "-u-" (under) or "-o-" (over) flashes in the viewfinder's LCD panel. *Exposure compensation cannot be used while in the manual mode.
Exposure Compensation Average Exposure Metering Mode (A) (Set the exposure metering mode selector lever to "A".) The average light of the entire picture area is measured, with emphasis on the center. Spot Exposure Metering Mode (S) (Set the exposure metering mode selector lever to "S".) The light in the circle at the center of the picture area is measured to determine the exposure. This mode is best suited for strongly backlit subjects, or when you desire to measure a specific area.
Single-Frame Mode/Continuous Mode Single-Frame Mode The film is advanced one frame at a time each time the shutter release button is pressed. Set the shutter release mode selector lever to "S". Continuous Mode Photographs are taken continuously as long as the shutter release button is pressed. Set the shutter release mode selector lever to "C". Photographs are taken continuously at a rate of about 1.2 frames per second.
Auto Bracketing Mode In situations which are difficult to confidently meter for exposure, use the Auto Bracketing function. In this mode, three frames are taken successively with different exposures set automatically (overexposure, standard and underexposure). Automatic exposure operation in the auto bracketing mode 1. Turn the mode setting dial and select "P", "Av" or "Tv". 2. Press the mode setting button “A” once to set the auto bracketing mode.
Multiple Exposure Mode With the multiple exposure mode, the same frame of film can be exposed multiple times. 1. Press the mode setting button ”A” twice to enter the multiple exposure mode. Canceling the Multiple Exposure Mode To cancel the multiple exposure mode before all the additional exposures have been taken, with the dark slide removed, half-press the shutter release button while pressing the roll film holder's manual film advance button “B”. 2.
Self Timer Mode With this function, under the default setting the shutter is released 10 seconds after the shutter release button is pressed. The self timer lamp flashes slowly for the first 7 seconds, then flashes quickly for the last 3 seconds before the shutter is released. Use this function to take group photos or to photograph yourself. 1. Fix the camera to a tripod. 2. Press the mode setting button “A” three times to set the self timer mode. 3.
Extended Exposure Modes (Bulb and Time Modes) To expose the film for extended times (over 30 seconds), set the shutter speed to bulb or set the exposure mode setting dial to "T" (Time Mode). Bulb Mode The bulb mode uses electronic control, so the batteries are in constant use during the entire exposure. 1. Turn the exposure mode setting dial and set it to “M" (manual mode). 2. Turn the front dial counterclockwise to select "bulb", then turn the rear dial to set the aperture.
AE Lock Mode When the AEL button “C” is pressed, the exposure is locked to the value metered at that time. Use this when the object you want to use for exposure metering and the object on which you want to focus are different or when you want to take continuous photographs without changing the exposure. 1. Set the shutter release mode selector lever to “S”. 2. Turn the exposure mode setting dial and select "P", "Av" or "Tv". 3.
Taking Photos with the Mirror Up Use this when you want to avoid even the slightest shocks, for example when taking photos with a slow shutter speed using a tripod, with a telescopic lens, for close-ups, reproductions, etc. Neither the auto focus mechanism nor the exposure metering mechanism function when the mirror is raised. Set the focus and exposure compensation before raising the mirror. To prevent the camera from moving, use both an electromagnetic cable release (sold separately) and a tripod.
Depth of field Depth of field (D.O.F) 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 via the depth of field preview button (See page 66.), the D.O.F 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 white index mark in the center of the scale.
Flash Photography In addition to its standard flash sync system, the Mamiya 645 AF features TTL (through the lens), off the film (OTF), electronic flash exposure automation. A flash sensor located inside the camera body reads the flash reflected off the film surface at the moment of exposure. The sensor is connected via the Mamiya 645 AF's dedicated hot-shoe to a shoe- or handle-mount style Metz flash unit via the Metz SCA 3951 TTL Adapter. Maximum flash sync speed is 1/125 sec.
Depth of Field Preview/Eyepiece Shutter Flash Photography with Flashes other than Metz Flashes 1. Mount the flash onto a flash bracket or if it is a handle-mount style flash attach to the bottom of the camera. Do not attach a dedicated flash unit to the camera's hot shoe that is not designed specifically for the Mamiya 645AF. To use this type of flash, use a flash bracket or other means, and connect the synchro cord to the camera's synchro terminal.
Changing The Focusing Screen 1. Remove the lens. 2. Slide the Focusing Screen Release lever “A” forward, as illustrated, to the left with the tweezers to let be Focusing Screen down. Using the M645 Manual Focus Lenses When using the M645 manual focus lenses, mount the exclusive viewfinder screen #314474 (sold separately) and set the focus mode to "M" (manual) to enable shooting with stop down metering. 1. Mount the M645 lens to the body, set the focus, then set the lens' A/M lever to "M".
External Power Supply When using an external battery case for cold weather operation (sold seperately), connect it to the external power socket. 1. Set the shutter mode selector lever to "L". 2. Remove the cap. Use a coin, etc., to remove the external power socket's cap. 3. Remove the batteries from the camera's battery case. Turn the battery case detach lever, remove the battery case, remove the batteries, then re-insert the battery case into the body and lock the battery case lever again. 4.
Electronic Dial Operations Front/Rear Dial Lock Mechanisms (select "dLoc°") When the Electronic Dial Lock is "On", all currently set values in "Av" (Aperture Priority AE), "TV” (Shutter Priority AE) and "M" (Manual mode) cannot be adjusted with the front or rear dials. This prevents accidental adjustment of shutter speed or aperture values. 1. Set the shutter release mode selector lever to "S" (to turn the power on). 3. Turn the front or rear dial and select "dLoc". to register the setting.
Superimposing Data (the data is superimposed on the film outside of the image area) This function allows you to superimpose exposure or date information on the film outside the image area. When selected, the superimposing mode is displayed on the main LCD. Setting the Date and Time 1. Set the shutter release mode selector lever to "S" (to turn the power on). 2. Press the “F2” Key for about 2 seconds. "SEt 1" appears on the main LCD panel. 3.
Selecting the Data to be Superimposed (select "Func") There are two data modes which will superimpose information onto the film. If you do not desire to superimpose any information, this function may also be switched off. 1. Set the shutter release mode selector lever to "S" (to turn the power on). 2. Press the “F1” Key for about 2 seconds to display "Func" on the main LCD panel, then press the “F1” Key again. 4.
Changing the Viewfinder Display in the Manual Mode"M" (select 'Fd") When the exposure mode setting dial is set to "M", it is possible to display only the focus marks and flash charge mark in the viewfinder's LCD panel. This is useful when exposure settings will not change, and this information in the viewfinder could be otherwise distracting. 1. Set the shutter release mode selector lever to "S" (to turn the power on). 2.
If the shutter cannot be released ●The shutter cannot be released when the batteries are discharged or no batteries are loaded. ●The shutter cannot be released while the film is being advanced. ●The shutter cannot be released while the flash is charging (while the flash mark is flashing) when the shutter release mode is set to "C" (continuous shooting) with a Metz flash mounted with the SCA 3951 adapter. The shutter can be released once flash charging is completed.
