Mamiya 211125, 645 AF manual AE Lock Mode, How to meter and focus at two different distances

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 se-

lect "P", "Av" or "Tv".

3.Focus on the object you want to use for expo-

sure metering, then with the shutter release button half-pressed Press the AEL button “C” once on the

rear of the grip. [ ] appears on the viewfinder's liquid crystal display panel, indicating that the exposure is locked.

4.With the shutter release button still half- pressed, aim the camera to achieve the desired composition, then release the shutter.

*When the shutter release mode is set to "S" (single-frame advance mode), the AE lock mode is canceled when the shutter release button is pressed. If you wish to take a series of photos using the AE lock function, switch the shutter release mode to "C" (continuous advance mode).

*To cancel the AE lock mode before taking a photo, press the AEL button “C” again. *The focus is locked in "S" mode when the shutter release button is half-pressed. *When the AEL button “C” is pressed in, the difference between the metered exposure and exposure with the new composition is displayed in the viewfinder's LCD panel. *The AE lock mode is canceled 5 seconds after the AEL button “C” was pressed.

*If the difference between the set value and the metered value exceeds 6EV,

"-u-" (under) or "-o-" (over) flashes on the viewfinder's liquid crystal display

NOTE:

After setting the AE lock mode, the front or rear dial can be used to change the aperture and shutter speed without changing the exposure set with the AE lock function.

When the exposure mode is set to "P" (program AE), turning one of the dials shifts the program between PH and PL. When the exposure mode is set to "Av" (aperture priority AE) or "Tv" (shutter priority AE), turning one of the dials changes the shutter speed or aperture changes, respectively.

Use of the exposure compensation dial during AE lock will change the shutter speed in Av Mode and the aperture in Tv Mode. In the "P" Modes, exposure compensation during AE lock will affect aperture and/or shutter speed, dependant upon the conditions and the program shift mode selected. In all three situations, the exposure compensation will be displayed to the left of the exposure settings in the viewfinder's LCD panel.

How to meter and focus at two different distances
