[. . . ] Preface Congratulations on your purchase of the Mamiya 645 AFD Camera. 1 2 3 4 5 Note: Mamiya pioneered the 645 SLR system camera three decades ago and the Mamiya 645 AFD , with its TTL auto-focus, auto-exposure, auto-flash and auto-film winding features is the latest Mamiya masterpiece and reflects its long tradition of medium format camera expertise. Special Advice To Professional Photographers Your Mamiya 645 AFD is designed for heavy professional use and will give you a long service life if properly maintained. Your camera and lenses have many moving parts which require periodic lubrication. Its electronic components, too, are subject to wear and tear and are affected by ambient conditions like dust, sand, sea air, heat and moisture. If cameras had odometers like automobiles, it would be easier to specify servicing schedules. [. . . ] In the B (Bulb) mode, the difference with the metered value is not displayed. 2 1 2. Turn the rear dial to set the desired aperture. 3. Turn the front dial to set the desired shutter speed. When the set value matches with the metered value, the difference indicator will show "0. 0". When the difference between the set value and the metered value is greater than 6EV and the set value is lower the metered value, the indicator in the viewfinder LCD shows "­ u ­. " Contrarily when the set value is higher than the metered value, the indicator shows "­ o ­. " 1. Increment of the aperture and shutter speed value can be set at either 1/3 or 1/2-stop. The assignments of the front and rear dials can be swapped. Rotation direction of the dials to change the values can be altered. The dial selected aperture level can be locked. Page 77 57 58 One-push shift function When difference between the set value and metered value is displayed on the viewfinder LCD in the Manual "M" mode, press the AEL button for approx. 1 second and the camera will automatically adjust the shutter speed to achieve the correct exposure based on the set aperture value. X Mode (X) Select this mode when you use a flash. The shutter speed will be fixed of 1/125 second of the synchronized speed. While the difference between the set value and the metered value is displayed on the viewfinder LCD, press the AEL button for approximately one second. The camera changes the shutter speed to an appropriate level. When you take a photograph with TTL light metering with a Metz flash, see pages 81 and 82. For flash photography, see pages 80 to 84. 1. The selected aperture value can be locked. Custom settings (C-25 on page 92) See page 77 CF (Custom Function) mode (CF) You can change the camera functions and methods for using the camera using custom functions. 1. The one push shift function can be disabled. The aperture level can be selected for the parameter to shift. Custom settings (C-22 on page 92) For the details of the custom functions, see pages 86 to 95. 59 60 Exposure Metering Modes How to change to the Exposure Metering Modes While pressing the exposure metering mode selector lever lock release button in, turn the exposure metering mode selector lever up or down. If a polarizing filter is necessary, use a circular polarizing filter. A linear polarizing filter is not compatible with the Mamiya 645 AFD and its operations. A Average/spot auto switching exposure metering mode (A-S AUTO) (Set the exposure metering mode selector lever to "A-S". ) With the A-S auto metering mode, average or spot exposure metering is selected automatically and the appropriate exposure is set accordingly. The spot mode is selected automatically when the brightness within the spot metering area is lower than the brightness of the average metering area by about 1. 5 EV or greater. The average mode is selected when the spot exposure metering value is the same or brighter than the average value. When the difference between the spot value and average value is between 0. 75 and 1. 5 EV, the appropriate exposure is achieved at an intermediate value. O AU T A-S S A A-S S AUT O Center 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. A A- S 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. [. . . ] · Battery life differs, depending on frequency of use, type, age, storage condition, ambient temperature (use External Battery Case in very cold weather), etc. · Always remove the battery (and film) when camera is not used for a long period of time. · Always keep covers on lenses and camera body. · Do not store the camera at temperatures exceeding 40°C (105°F) and -10°C (15°F).
