Shutter Speed and Aperture
The Shutter Speed Dial
When the Shutter Speed Dial is set to �B� (bulb). the shutter will remain open as long as pressure is applied to the Shutter Release Button and will close as soon as pressure is released. The 0 mark which appears between �B� and 400 on the Shutter Speed Dial is the setting for the AE Finder (which will be available in the future). When set at this position. the dial locks in place. To unlock it, rotate the dial while depressing the Lock Release Button which appears in the center of the dial.

The Aperture Ring

I

Select the shutter speed desired and rotate the Shutter Speed Dial until the appropriate figure is aligned with the shutter speed index mark. The Shutter Speed Dial must be set to a click-stop position and can not be used at in-between settings. The numerals as they appear on the dial and the shutter speeds they represent are shown in the following table.

To set the diaphragm to a desired aperture, rotate the Aperture Ring until the appropriate figure is aligned with the central index line. It is perfectly acceptable to use the Aperture Ring at in-between click-stop settings. When the Shutter Release Button is depressed, the diaphragm will automatically stop down to the preselected aperture before the shuner opens for the exposure.
