DEPTH-OF-FIELD PREVIEW

When the lens is focused on a subject, there is a range behind and in front of the subject that appears sharp. This is the depth-of-field. To check how much of your scene will appear in focus, press the depth-of-field preview button. The lens is stopped down to the aper- ture that appears in the display.

The magnification ratio is the ratio of the actual size of an object to the size of its image on the film plane.

If an object is actually 12 mm in size, and the image is also 12mm in size, then the magnification ratio is 1:1. If the image size is 6mm, then the magnification ratio is 1:2.
