Olympus OM-2, zm2000qdk manual Aperture Ring and Manual Shutter Speed Ring

APERTURE RING AND MANUAL SHUTTER SPEED RING

Aperture Ring

The opening (aperture) in the lens diaphragm is

marked in F stops on the aperture ring. The higher

the F number, the smaller the lens opening (less

light) and provides greater depth of field than lower F numbers (see page 25).

When setting the aperture ring, you may use either

the click-stop positions or any in-between settings

to obtain precise exposure control.

NOTE: All lenses in the OM System (except cer-

tain specialized lenses) provide fully automatic

diaphragm control allowing you to focus and

compose your picture with the lens fully open. The diaphragm will automatically close to the

pre-selected F stop at the moment of exposure.

And immediately re-open after exposure.

Manual Shutter Speed Ring

Shutter speeds engraved on the manual shutter

speed ring are used only for non-automatic cam- era operation. B indicates "bulb" at which set- ting the shutter will remain open as long as the shutter release button is held down. The other engravings indicate fractions of a second; for ex- ample "T" for 1 second, "2" for 1/2 second .....

up to "1000" for 1 /1000 second. To set at "B",

rotate the ring while pressing the B LOCK but- ton at the lower left of the body mount.

Be careful that shutter speeds are set only at click stop positions. Make sure that the selector

lever is set at a click stop position.
