Do not place your fingersor other objects on top of the Speedlight while shooting. If the Speedlight is helddown when the shutter-release button is pressed halfway, a message will be displayed( 150). Pictures can still be taken, but neither the built-in Speedlight nor optionalSpeedlights will fire.Light from the flash reflected from particles of dust or other matter in the air may ap-pear in pictures as bright specks. If this occurs, turn the flash off or zoom in and tryagain.Keep your fingers and other objects away from the flash window when the built-inSpeedlight is raised.Lens HoodsRemove lens hoods (available separately; 143) when using the flash.When Lighting Is PoorWhen lighting is poor and the flash is off ( ) or set to slow sync ( ), shutter speedslows and pictures may be blurred. Blurring can be reduced by turning vibration reduc-tion (VR) on, which also reduces the effects of shake in the shooting display ( 45). Atspeeds slower than ¼ s, the shutter-speed indicator in the monitor or electronic view-finder will turn yellow to indicate that dark areas of the image may be slightly mottled.Mottling can be reduced by turning noise reduction on ( 109). At speeds slower than1/30 s, we recommend using a tripod or resting the camera on a steady, level surface.Turn vibration reduction (VR) off when using a tripod ( 45).In (auto) or scene modes, or when sensitivity ( 52) is setto AUTO in P, S, A, or M modes, the camera will automaticallyincrease sensitivity in response to lighting conditions, permit-ting faster exposures and minimizing blur caused by inadver-tent camera movement (camera shake). An ISO icon will bedisplayed to warn that pictures may be slightly mottled.Red-Eye ReductionIf the camera detects red-eye after the pre-flash has fired, advanced red-eye reductionprocessing is used to further reduce red-eye, slightly increasing the time required beforethe next picture can be taken. In extremely rare cases, portions of the image outside thearea of red-eye may be affected; if this occurs, change the flash setting and try again.Speedlight Options ( 104)The Speedlight opt. item in the shooting menu contains options controlling the built-in and optional Speedlights.ISOISOISO8M8M8MF2.8F2.8F2.81/60601/60 126126126
