a: Manual Exposure

You can set both the shutter speed and aperture as desired. With flash, the flash exposure will be set automatically to match the aperture that was set. The flash sync speed can be set within 1/200 sec. to 1/30 sec. or to bulb.

The exposure level indicator in the viewfinder indicates the exposure level up to ±2 stops from the standard exposure index at the center. While you change the shutter speed and aperture, the exposure level mark will move. You can decide which exposure level to set.

Bulb Exposures

In step 2, turn the <6> dial to the left to set <BULB>. A bulb exposure keeps the shutter open for as long as you hold down the shutter button. It can be used to photograph fireworks, etc. The elapsed exposure time will be displayed on the LCD monitor.

For bulb exposures, using a tripod and Remote Switch (p.194) is recommended.

Since bulb exposures produce more noise than usual, the image might look rough or grainy. You can reduce this noise by setting the [7 Custom Functions (C.Fn)] menu’s [Long exp. noise reduction] to [1: Auto] or [2: On] (p.185).

The Auto Lighting Optimizer (p.186) will not work.
