Handling the Camera / Holding the Camera
Hold the camera grip firmly with your right hand while supporting the
camera or lens with your left hand. Make sure that your fingers are
not blocking any of the camera's features; they should fit securely
around the grip. To hold the camera steady, always keep your elbows
at your side and your feet shoulder-width apart for support. Always
keep the camera strap around your neck or wrist in the event you
accidentally drop the camera.
How to press the shutter-release
The shutter-release button has three positions. Press the shutter
release button partway down to activate the camera's autofocus and
autoexposure systems. Gently press the shutter-release button all the
way down to take the picture (never with a quick jab).
