Focusing Tip: Zoom In (Basic)

If you have a zoom lens and your camera is having difficulty focusing, try to zoom in to get a larger image, half-press the shutter to lock focus on your subject, then zoom out. Even though you zoom out, the focus will be maintained so long as the distance between the camera and the subject remains constant (this characteristic of modern lenses is called "confocality").  You can try this out to confirm :)
