Exposure Control

The top and rear LCD panels are provided with
illumination so you can read the panels in the dark.
The <

> button turns the illumination of both panels

on or off. The illumination stays on for 6 sec. If you
take a picture while the panel is illuminated, the
illumination will turn off 2 seconds after the picture is
taken. If you take a bulb exposure while the panel is
illuminated, the illumination will turn off immediately.

Pressing any button while the LCD panel is illuminated prolongs the illumination.

After the long or bulb exposure is taken, the noise reduction processing time will be
as long as the exposure time. During the noise reduction processing, “

” will be

displayed on the top LCD panel. You cannot shoot until it disappears.

Noise reduction can reduce noise in long (slow shutter speeds) or bulb exposures and reduce
horizontal stripes in images taken at high ISO speeds.

Setting

On 1

Noise Reduction Description

Noise occurring during long or bulb exposures is reduced for ISO 100 to 3200.

On 2

The horizontal stripes that appear at high ISO speeds with the On 1 setting is reduced
for ISO 200 to 3200. The noise occurring during long or bulb exposures is also reduced.
Since the dynamic range will be narrower than the On 1 setting, check the image
characteristics before using this setting.
