Operating Tip

Halfway and fully pressing the shutter button

'Halfway' means lightly touching the shutter button to

activate the camera. 'Fully' means pressing the button

all the way in one movement to operate the shutter.

White walls and bright blue, cloudless skies can be

tricky subjects for any SLR camera autofocus system.

Alternatively, the subject you're focusing might be off

at one extremity of the scene and not covered by the

focus frame. These are times when Focus Lock can be

useful, allowing you to 'freeze' focus on a particular

point before composing your picture.
