Shutter

Turn the shutter speed dial clockwise or counter-clockwise to the shutter speed desired. The shutter speed may be set either before or

after cocking the rapid wind lever. As you cock the shutter by turning the rapid wind lever, the "cocked" indicator turns red showing that the shutter is cocked.

The indicator window blacks out as you trip the shutter button. For use of the X setting on the shutter speed dial, refer to page 18.

With the shutter speed dial set on B (bulb), the shutter will stay open as long as you depress the shutter button. As you release your finger from the shutter button, the shutter closes. When a long exposure is desired while using the B setting, attach a shutter release cable with a locking device to the shutter button. This will permit a "Time" exposure.

Cautions

1 At slow speeds - slower than 1/30 - support your camera rigidly or use a tripod to prevent movement of your camera.

2To protect the shutter mechanism, trip the shutter release before putting the camera out of use for any extended period.

If you want to know how great the depth of field is at a certain aperture, look at the

depth-of-field guide. In the above photograph, the distance scale is set at 5 meters…the lens is focused on a subject 5 meters away. The calibrations on each side of the distance index correspond to the diaphragm setting and indicate the range of in-focus distance for different lens apertures. For example, if the lens opening of f/8 is to be used, the range on the distance scale ring covered within the figure 8 on the depth-of- field guide indicates the

area in focus at the lens opening. You will note from the depth-of-field guide in the

photograph that the range from approximately 10 to 25 feet is in focus. Note that as the lens apertures change, the effective depth of field also changes. For the depth of fields at different apertures and distances, refer to page 14 ~ 15.

Depth of field is the range between the nearest and farthest distances which are in focus at different lens apertures.
