Step 4: Focus

Press the shutter-release button halfway to

focus.

The camera will select the focus points

automatically.

If the subject is poorly lit, the flash

may pop up and the AF-assist illuminator may

light.

2 Check the indicators in the viewfinder.

When the focus operation is complete, the

selected focus points will be briefly highlighted,

a beep will sound (a beep may not sound if the

subject is moving), and the in-focus indicator (I)

will appear in the viewfinder.

While the shutter-release button is pressed halfway, the number of exposures

that can be stored in the memory buffer (“t”; 0 53) will be displayed in the

viewfinder.

Step 5: Shoot

Smoothly press the shutter-release button the rest of

the way down to release the shutter and record the

photograph.

The access lamp next to the memory

card slot cover will light and the photograph will be

displayed in the monitor for a few seconds (the photo

will automatically clear from the display when the

shutter-release button is pressed halfway).

Do not

eject the memory card or remove or disconnect the

power source until the lamp has gone out and recording

is complete.
