This is the simplest shooting mode with this camera. ( p.18)• You cannot use intermediate positions between shutter-speed dial clicks.• In B (Bulb) mode, the shutter operation is performed mechanically (not electroni-cally). However, a very small amount of battery power may be drained. Therefore,we recommend you remove the battery to save the battery power when you plan totake many pictures using B mode.TipsLocking and releasing the shutter-speed dial:Once you set the shutter-speed dial to “A,” the dial is locked to prevent inadvert-ent changes.... To move the dial to another position, rotate the dial while holding down theauto-lock release button at the center of the dial.• Depending on the conditions and yourintention of shooting, align the shutter-speed index to the figures or marks onthe shutter-speed dial.You may choosefrom among the following shootingmodes:1 to 1/4000 second (Manual mode)In Manual mode, you can set both the shutter speed and aperture manually to createvarious creative photographic effects. ( p.20)B (Bulb mode)In this mode, the shutter stays open as long as the shutter-release button is depressed. Usethis function when shooting scenes that require extended exposure (e.g., night time stars,etc.). For very long exposures, use a tripod, and instead of holding the shutter-release buttondown with your finger, you can lock the shutter release open by using the AR-3 cable release(sold separately), to take steady, long-exposure shots without worrying about “camera shake.”
