Advatages and disadvantages of each focusing zone

Each focusing aid works best in certain situations. For instance, you may prefer split-image focusing when you're photographing a building because there are straight lines to focus on. But if you're taking a picture of a crowd of people where prominent lines are hard to find, the microprism and ground-glass systems of focusing are easier and faster. In addition, the ground glass offers the advantage of showing you what part of the picture is in the plane of sharpest focus relative to other parts of the picture. The ground glass also lets you preview depth of field over the entire image area if your camera has the feature that permits this.

Practice focusing your camera until you do it so naturally that you don't have to give it a second thought.
