Part I

Using the Sony Alpha A700

Semiautomatic and

Manual Exposure

Modes

The Mode dial is used to set the Semi-

automatic and Manual Exposure mode. It's

as easy as turning the dial to the desired

mode.

Auto. Setting the camera to the

Auto mode gives control of all

exposure settings to the camera.

The A700 allows you to change the

white balance, ISO, Creative Style,

D-Range Optimizer, Flash mode,

exposure compensation and ﬂash

compensation, Focus mode, Drive

mode, image quality, and image

size. When the dial is moved from

the Auto setting to any of the other

modes settings and then back to

Auto, all the changes except for

image quality and image size are

reset to the default settings.

Program Exposure. Although the

Program mode and the Auto mode

might seem similar, they differ in

some very important ways. The

shutter speed or the aperture can

be adjusted by using the Front and

Rear control dials. Any changes

that are made in this mode are

reset if the Mode dial is moved.

Aperture Priority. In the Aperture

Priority mode, you set the aperture,

and the camera sets a shutter

speed to achieve proper exposure

based on the Metering mode. The

aperture is set by using either the

Front or Rear control dial.

Shutter Priority. In Shutter Priority

mode, you set the shutter speed

and the camera sets the aperture

to achieve proper exposure based

on the Metering mode. The shutter

speed is set by using either the

Front or Rear control dial.

Manual Exposure. In this mode,

you set both the aperture and the

shutter speed. By default, the Rear

control dial controls the aperture,

and the Front control dial controls

the shutter speed. As the aperture

and shutter speed are changed,

the camera displays how close

your selected exposure is to the

metered exposure on the EV scale.

Drive Modes

The A700 has eight different Drive modes.

The Drive modes are set using the Drive

menu, which is accessed by pressing the

Drive mode button on the top of the cam-

era. The drive menu can also be accessed by

pressing the Function button to bring up the

Quick Navigation screen and using the

multi-selector to navigate to the Drive

mode.
