Manual Mode (M)

This mode is used to set both the aperture and shutter speed for total exposure control. Shutter speeds can be selected from B (bulb), 30 seconds to 1/4000 of a second. Aperture values can be set from the open to the minimum aperture. B (bulb) can also be specified in this mode.

1.Hold down the button and turn the exposure mode setting dial to “M” (Manual) position.

2.Turn the rear dial to set the desired aperture.

3.Turn the front dial to set the desired shutter speed.

4.When the shutter release button is halfpressed, the difference between the present settings and the metered value is displayed in the viewfinder’s LCD panel. The value is displayed in 1/3 stop increments within a range of ±6 EV.

Notice:

When the set value matches with the metered value, the difference indicator will show “0.0”. When the difference between the set value and the metered value is greater than ±6EV and the set value is lower the metered value, the indicator

in the viewfinder LCD shows “– u –.” Contrarily when the set value is higher than the metered value, the indicator shows “– o –.”
