Setting the Aperture Value and Shutter Speed Manually (M Mode) With the mode dial set to M (Manual mode), you can manually select both the aperture and the shutter speed. In this shooting mode, you can also set the camera in the bulb mode for long exposures. However, please remember that bulb shutter release is limited to 8 min. Exposure will end and the shutter will release after 8 min if you hold down the shutter button longer than 8 min. Slow Shutter speed Fast 2 OFF ON 1 1 Set the mode dial to M (Manual mode). 2 Turn the main dial to select the aperture value, and turn the sub dial to select the shutter speed. Every movement of the dial changes the aperture value and shutter speed in 1/3 steps. 2 Aperture value Small aperture Large aperture You can select the shutter speed as follows: • IS mode: 1/640 - 60 sec. • PS mode: 1/4000 - 60 sec. or 1/18000 sec. • "bulb" If you select "bulb" then the shutter will remain open for as long as you keep the shutter button pressed down (to a maximum of 8 min). This is called the bulb shooting mode. Note • If you set the aperture value and shutter speed manually, that setting will remain in effect even after you switch to another shooting mode or switch the camera off and on. If you set the camera in the shooting mode again, the camera will return to the same aperture value and shutter speed. • A prolonged shooting (with a slow shutter speed) consumes more battery power and the shooting may not be completed depending on the type or condition of the batteries. In that case, use an optional B-12LPB/B-10LPB lithium polymer battery or CAMEDIA-brand AC adapter. • If you repeat a prolonged shooting, the number of pictures which can be taken may be severely reduced. 76
