Mamiya 645 AF, 211125 manual Time Mode T

*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.

*When the difference between the manual setting and the metered value is displayed in the viewfinder's LCD panel while in the manual mode and the exposure compensation dial is set to a position other than "0", the value displayed is the difference between the manual setting and the metered value plus the exposure compensation value. This has no effect on the exposure.

There are three exposure metering modes: "A" in which the average light of the entire picture area is measured with emphasis on the center, "S" in which the light in a spot at the center of the picture area is measured, and "A-S" which combines these two to automatically switch the mode according to the extent of difference between the brightness of the light metered in the two modes. The distribution ratio of the exposure metering modes is set within an intermediate range.

See pages 45-46 for Exposure Metering modes. See page 47 for Film Advance modes.
