Minolta 800si instruction manual DEPTH-OF-FIELD Preview, Setting Film Speed Manually

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 range is called 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 aperture that appears in the data panel. If the aperture is small (large f- number) the image will look darker through the viewfinder. This is normal.

•The exposure setting cannot be changed while the depth-of-field preview button is pressed.

Depth of field can be increased by:

1.Using smaller apertures (larger f-stop numbers).

2.Using short focal length (wider angle) lenses.

3.Moving farther away from your subject.

SETTING FILM SPEED MANUALLY

The film speed can be set manually when you want to override the DX-coded film speed or you are using non-DX-coded film. Film speeds can be set from ISO 6 to ISO 6400 in 1/3EV increments.

•If a film speed is not set for non-DX-coded film, the ISO of the previous roll will be automatically used.

Load the film, then press the ISO button in the control panel.

Turn either control dial to

change the ISO value.

When the desired value appears in the data panel, press the shutter-release button partway down to enter the selection.

•For flash exposures, we recommend film speeds between ISO 25 and 1000.
