❚❚ The Built-in Flash The built-in flash has a minimum range of 0.6 m (2 ft) and can not be used in the macro range of macro zoom lenses. It can be used with CPU lenses with focal lengths of 24 mm (16 mm in DX format) to 300 mm, although in some cases the flash may be unable to entirely light the subject at some ranges or focal lengths due to shadows cast by the lens. The following illustrations show the effect of vignetting caused by shadows cast by the lens when the flash is used. Shadow Vignetting Remove lens hoods to prevent shadows. The flash may be unable to light the entire subject with the following lenses at ranges less than those given below: Lens AF-S DX NIKKOR 10-24mm f/3.5-4.5G ED AF-S DX Zoom-Nikkor 12-24mm f/4G IF-ED AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II AF-S DX VR Zoom-Nikkor 18-200mm f/3.5-5.6G IF-ED AF-S DX NIKKOR 18-300mm f/3.5-5.6G ED VR Zoom position 18-24 mm 18 mm 20-24 mm 20 mm 24-55 mm 18 mm Minimum distance without vignetting No vignetting 1.0 m/3 ft 3 in.
