Mamiya 645 AF Taking Photos with the Mirror Up, Using auto focus and auto exposure, Manual mode

Taking Photos with the Mirror Up

Use this when you want to avoid even the slightest shocks, for example when taking photos with a slow shutter speed using a tripod, with a telescopic lens, for close-ups, reproductions, etc.

Neither the auto focus mechanism nor the exposure metering mechanism function when the mirror is raised. Set the focus and exposure compensation before raising the mirror. To prevent the camera from moving, use both an electromagnetic cable release (sold separately) and a tripod. Instructions for use of electromagnetic cable release on page 80.

Using auto focus and auto exposure

1.Turn the focus mode selector lever and set it to “S”.

2.Turn the exposure mode setting dial and set it to "P", "Av" or "Tv".

Look through the viewfinder, determine the focus, composition and exposure, then half-press the shutter release button. (Use the electromagnetic cable release (sold separately) or cable release to maintain the half-pressed status.

3.Press the AEL button.

When the AEL button is pressed, the AE lock mark [ ] appears in the viewfinder's LCD panel. Turn the body's mirror up lever towards "M.UP" until it stops to raise the mirror.

4.Press the shutter release button to take the photo.

*After taking a photograph with the mirror up, when the shutter release button is pressed “-no-RE" flashes on the main LCD panel and the shutter is locked. *To cancel the AE lock mode, press the AEL button again.

*Leaving the mirror up for long periods of time can result in film fogging. After taking a photograph with the mirror up, be sure to set the mirror up lever back to its original position.

*As a safety precaution, the mirror up lever does not work when no lens is mounted on the body.

*The lens cannot be removed when the mirror is up.

In the manual mode

1.Turn the focus mode selector lever, select "M", then turn the lens focusing ring to focus.

2.Set the exposure mode setting dial to "M", then use the front and rear dials to set the measured shutter speed and aperture.

3.Turn the body's mirror up lever towards "M.UP" until it stops to raise the mirror, then press the shutter release button to take the photo.

•If the lens is pointed at the sun with the mirror turned up and left like this, the sunlight entering from the lens may focus on the shutter blades and damage them. In this situtation, put the mirror up right before the moment of exposure and return the mirror to the down position directly after the exposure.
