1Set the mode dial to A.

2Select an aperture value using the control dial.

•The aperture range depends on the lens.

•The aperture value is adjusted in 1/3 Ev increments.

•Before shooting, you can do a quick check on the image blur with the depth-of-field preview function (page 70).

•If the proper exposure is not obtained after making the settings, the shutter speed on the LCD monitor and in the viewfinder flashes when the shutter button is pressed halfway down. You can shoot at this point, but adjusting again is recommended.

•When the flash is pulled up, the flash fires regardless of the amount of ambient light (page 54).

•When using the flash, if you close the aperture (a larger F-number), the flash light does not reach a distant subject. Opening the aperture (a smaller F-number) is recommended.

•If you close the aperture (a larger F-number), the amount of light passing through the lens is decreased and the shutter speed becomes slower. Using a tripod is recommended.

zShooting techniques

The depth of field is the in-focus range. Opening the aperture makes the depth of field shallower (the in- focus range becomes narrower) and closing the aperture makes the depth of field wider (the in-focus range becomes wider).
