Depth of Field

When your subject is in focus, there is a certain area in front of it and behind it which will also be in focus. This range of sharpness is called "depth of field".

Depth of field has the following characteristics:

1)The smaller the aperture, the wider the depth of field and vice versa.

2)The shorter the lens focal length is, the greater the depth of field, provided that aperture and shooting distance are the same.

3)The farther the shooting distance, the greater the depth of field..

4)Depth of field is generally greater in the background than the foreground by a ratio of two to one.

To check the depth of field (1)

Push the depth-of-field check button and the camera will stop-down the aperture to either the automatically- calculated value (e.g. shutter-priority AK), or the one set manually (e.g. aperture priority AK). As you look through the viewfinder with the button pushed in, you can see the range of sharpness, i.e. the depth of field.

It is impossible to check depth of field when the main Twitch is set at the green " " [ ] " " mark

To check the depth of field (2)

Press the shutter button halfway and note the aperture value. Find the two aperture values on the depth-of- field scale on the lens which correspond to that value. Then draw imaginary lines from those two values to the distance scale. The effective depth of field lies between those two distances. For example, using a standard 50mm lens focused at 5m with the aperture set at f/11, depth of field extends from approx. 2.7m to 10m (approx. 8.8ft to 32.8ft) away. Any subject from 2.7m to 10m away will be in reasonably sharp focus.

There are some lenses which have no depth-of-field scale so follow (1).
