Features of the Crossover System and the AE (Auto Exposure) Mode
The Crossover System
The ZE-X Crossover System enables the camera to cross over automatically between the various AE modes in the
following circumstances:
1) Used with the shutter speed priority AE or aperture priority AE modes, it allows the camera to automatically
correct exposure settings in unforeseen situations when conditions are such that your pre-selected shutter speed or
aperture will not give you a correct exposure.
2) With the two modes mentioned above and in the programmed AE mode, it allows the camera to open the aperture
automatically and maintain a safe shutter speed, that is, a speed which is above the "camera shake" limit for the lens
in use. This ensures blur-free hand-held photography in all but the most extreme exposure conditions.
3) When the Mamiyalite MZ 36R and MZ 18R dedicated auto electronic flash units are used with the camera, the
Crossover System acts to prevent the flash discharging in exposure situations where correct exposure can be obtained
without flash, but automatically switches the camera back to the flash AE mode if the shutter speed drops below the
handheld "camera shake" limit. 4www.butkus.org
Shutter Speed Priority AE
In this mode, the camera sets the correct aperture for you, leaving you free to control the shutter speed. This type of
auto exposure is especially useful when you wish to deliberately blur your subject or the background by using a slow
shutter speed, or when you need to use a fast shutter speed to freeze the action. If you are a beginner without much
knowledge of photography, we suggest that you set the shutter speed to 1/125 second until you get the feel of it; with
the Crossover switch on, there will be no need to change shutter speeds for different lighting conditions.
Aperture Priority AE
Use of this mode allows you to select any aperture freer while the camera automatically matches it with the
appropriate shutter speed. This permits you to take full advantage of the different focusing characteristics of the lens
in us to create different effects with your pictures. Large apertures for example, can be used to highlight your subject
again an out-of-focus background, while small apertures will give greater overall sharpness to the entire photo.
Programmed AE (Total Auto)
With this mode, the camera's microprocessor selects both the shutter speed and the aperture according to the
prevailing light conditions. Since the camera sets up the exposure for you entirely, this mode is highly suitable for
candid photography and snapshots where there is no time or it is too much trouble for you to set the exposure controls
yourself. Naturally, it is also ideal for beginners, since there is little danger of exposure failure. In fact, we
recommend that you keep the camera in this mode while carrying it, so that you will always be ready for those once-
in-a-life time shots. This will also give you the option of switching directly to the shutter speed or aperture Priority
AE modes as needed.
Electronic Flash AE
When used in combination with the dedicated Mamiyalite MZ flash units, the ZE-X will automatically set the
aperture and synchronize for flash on charging, thereby making auto flash exposures as easy as normal auto
exposures. In addition, the Crossover System makes flash override possible in all of the AE modes.
