Special Advice To Professional Photographers Your Mamiya 645DF 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. [. . . ] When using a large flash unit for use in studios, changing the synchronizing speed is recommended. shutter speeds can not be achieved even though the leaf shutter lens is attached, try another exposure mode. The selected aperture value can be locked. See page 71 CF (Custom Function) Mode You can change the camera functions and methods for using the camera using custom functions.

P CF X Av CF C3 Tv C2 M X C1 P C3 C2 X M Exposure Modes (continued) Exposure Metering Modes There are three exposure metering mode to select a proper exposure modes appropriate to the lighting condition of subject. C1, C2 or C3 Modes Mode dial options "C1", "C2" and "C3" can be used to memorize preferred settings. These settings can be changed instantly to suit the photographer's needs. Programmable settings are exposure mode, "P" (program AE), "Av" (aperture priority AE), "Tv" (shutter speed priority AE), "X" (synchro mode), "M" (manual mode), focus area and spot metering. How to select an exposure mode 1. Exposure mode mark is displayed when the exposure mode button is pressed. Since three different exposure modes are displayed sequentially when either the front or rear dial is turned, select an appropriate exposure mode. CF C3 X M Av Tv 1. Go to the setting you wish to assign to "C1", "C2" or "C3". To record this setting, hold the set button down for one second until the details are displayed, then press the SET button while turning the mode dial to "C1", "C2" or "C3". When you release the SET button, the chosen setting will be programmed to your selection of "C1", "C2" or "C3". A B 2. Press the SET button or exposure metering mode button to enter the setting. CF Tv Av 1 3 2 Even when the power is switched off, the mode recorded will still be saved to C mode. "C1", "C2" or "C3" modes can be changed while photographing. However after taking a photo in a mode other than the modes selected in "C1", "C2" or "C3", when you turn the dial back to a C mode setting the change will not be saved. CF Tv M P C1 Exposure Metering Modes 4 * The illustration shows the exposure mode "Av" (aperture priority AE) being recorded to C2. Average/spot auto exposure metering Exposure metering is performed after automatically selecting average/spot exposure metering. · Depending on the subject conditions, centerweighted average/spot exposure metering is selected automatically, and the correct exposure is measured. · Spot exposure metering is automatically selected when the brightness of the spot exposure metering range becomes darker than the brightness of the entire screen. · If there is very little difference between the spot exposure metering value and center-weighted average exposure metering value, the correct exposure level is obtained as the intermediate value. The average brightness of the entire screen is measured, emphasizing the center of the screen. X C2 Programming C1, C2 or C3 C1 P M X C1 C2 C3 C2 Av C2 P Center-weighted average/spot exposure metering Center spot exposure metering The brightness of an area equivalent to 7. 6% at screen center is measured, and the exposure is determined. This mode is suited to measuring subjects with strong contrasts or measuring only screen portions. Exposure Metering Modes (continued) / Exposure Important warnings Exposure Compensation In some situations, such as a great difference between the subject and background brightness or overall subject tones that will not meter correctly because they are all black or white, the resulting photograph may be under- or overexposed. Exposure compensation can also be used when you want to intentionally create overexposed or underexposed pictures. When exposure compensation button is pressed, appears on the external LCD. When the front or rear dial is turned counterclockwise, the exposure is increased; conversely, when it is turned clockwise, it is decreased. [. . . ] Synchro speed can be changed away from terminal.
