Focus and Zoom

Focus is a manual feature on the camera that adjusts between a closer focus and a more distant focus to create the sharpest image. When focusing a shot, you should first zoom in on the subject and adjust the focus ring until the image is sharp, and then zoom out to the desired framing. If your subject becomes out of focus, it's important to know what direction to turn the ring so you don't create a more blurry image, and the focus is pulled to your subject. A different camera feature is exposure, which changes the brightness of your shot by controlling the amount of light that comes through the lens.
When changing the exposure, the main focus should be properly lighting the subject so that they don't appear too bright or too dark. To check if your subject is properly exposed, you can manually adjust the iris wheel to see how your lighting changes, and whether the image is enhanced or downgraded.
