Additional information
The relation between the shutter
speed and aperture
To shoot clear images, selecting the proper
exposure is very important, adding to the
chance of achieving the proper focus. The
exposure is an amount of light that is
determined by the shutter speed and
aperture value. The shutter speed is adjusted
by the time, longer or shorter. The aperture
is adjusted by the scale of the lens hole,
larger or smaller. When the shutter speed is
faster by one step, the aperture is opened by
one step to get the same exposure.
The movement of the program diagram
The program diagram shows the movement of the combination of the shutter speed and
aperture value.
The program shift function (page 54) quickly shifts the combination of exposure that the
camera has decided upon.
Program diagram (example)
The movement of the program shift (EV: 10, ISO sensitivity: 100) (example)
• When the EV value remains the same, the brightness of the recorded image is the same.
