[. . . ] DX Nikkor lenses are specially designed for use with Nikon digital-SLR (Nikon DX format) cameras, such as the D2-series and D40-series. When mounted on Nikon DX-format cameras, the lens' picture angle is equivalent to approximately 1. [. . . ] Turning the vibration reduction on and off Note: Be sure to set the switch 0 so that the indicator is precisely aligned with [ON]. Camera shake is reduced when the shutter-release button is pressed halfway. Autofocus and manual focusing, as well as precise framing of the subject, are simplified because camera shake visible through the viewfinder is also reduced. After pressing the shutter-release button halfway, wait until the image in the viewfinder stabilizes before pressing the shutter-release button the rest of the way down. If the camera is panned in a wide arc, compensation for camera shake in the panning direction is not performed. For example, with horizontal panning only vertical camera shake is reduced, making smooth pans much easier. Due to the characteristics of the vibration reduction mechanism, the image in the viewfinder may be blurred after the shutter is released. Do not turn the camera off or remove the lens from the camera while vibration reduction is operating. Failure to observe this note could result in the lens sounding and feeling as if an internal component is loose or broken when it is shaken. With cameras such as D300 and D40-series models, featuring a built-in flash, vibration reduction does not function while the built-in flash is charging. However, set the switch to [ON] when using a tripod without securing the tripod head, or when using a monopod. With autofocus cameras such as D2-series and D300 models, featuring an AF start (AF-ON) button, vibration reduction does not function even when the AF-ON button is pressed. However, there is no need to adjust the aperture setting to achieve correct exposures because the camera automatically compensates for this variable. Flash photography using cameras with a built-in flash Vignetting is the darkening of the corners around the image that occurs when the light emitted by the flash is obstructed by the lens hood 1, or lens barrel depending on the focal length or shooting distance. [. . . ] When the main subject in the focus brackets is relatively small When a person standing in front of a distant background is placed within the focus brackets, as shown in Fig. When the main subject is a finely patterned subject or scene When the subject is finely patterned or of low contrast, such as a field filled with flowers, as shown in Fig. [. . . ]
