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. [. . . ] The circle at screen center serves as a general guideline. 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. When this occurs, use the exposure compensation function. 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. The exposure compensation value can be checked on the external LCD or LCD inside the viewfinder. After taking the pictures, press exposure again to return the compensation button exposure compensation value to 0. The exposure compensation value mark on the external LCD is cleared, and the exposure compensation function is released. Exposure compensation is also possible during AE lock. The shutter speed changes with exposure compensation in manual mode ("M"). When a polarizing filter is used, ensure that a circular polarizing filter (circular filter: C-PL) is used. The correct exposure cannot be obtained with a normal polarizing filter (PL). With an inappropriate exposure setting, when shooting subjects that are too light or dark, the user is warned by the flashing external LCD or the LCD inside the viewfinder. At such times, the correct exposure cannot be obtained. Warnings that the exposure is outside the metering range Program AE (P) The shutter speed and f-number blink.

AE Lock Mode Shooting with the AE lock function is useful in cases where the desired focal point differs from where the focal point is usually measured, or when it is necessary to measure the exposure using spot metering in order to bring the desired subject into focus. The AEL button will lock the Auto-exposure value as the photo is being recomposed. Turn the exposure mode setting dial and select "P", "Av" or "T". CF Metered-value difference indicator Keep pressing the AEL button , and the difference between the metered exposure value and the exposure of the new composition will be displayed on the viewfinder LCD. This function can be used to see if an object of very different brightness levels can be properly captured. X M Av Tv A C3 C2 C1 2.
