Nikon D7100 manual 327

AThe Built-in Flash

The built-in flash can be used with CPU lenses with focal lengths of 16–300 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, while lenses that block the subject’s view of the red-eye reduction lamp may interfere with red-eye reduction. Remove lens hoods to prevent shadows. The flash has a minimum range of 0.6 m (2 ft) and can not be used in the macro range of macro zoom lenses. When DX (24×16) is selected for Image area, the flash may be unable to light the entire subject with the following lenses at ranges less than those given below:
