Using automatic focus and automatic exposure
The camera automatically focuses and adjusts the exposure for the current lighting conditions when you press the SHUTTER button halfway down.
The camera adjusts the focus and exposure automatically even if you press the SHUTTER button all the way down without pausing. But you are more likely to catch the perfect shot, especially when you are photographing an active subject, if you set the camera’s focus and exposure early. To do this, press the SHUTTER button halfway down, and then press the SHUTTER button all the way down at the exact moment you wish to capture the image.
Note | If the camera cannot find a focus or if the exposure |
| will be longer than 1/30 second, a yellow light |
| appears to the right of the viewfinder. You can still |
| take the picture, but the results might not be optimal. |

Using focus lock
The automatic focus feature focuses on the subject in the middle of the picture and requires good contrast within that subject area. If you do not want your subject to be in the middle of the image or if the subject lacks contrast, use focus lock.
