Note:
* When using the D100 camera, check the focal length and shooting distance before taking flash pictures to prevent vignetting since the light emitted from the flash may be obstructed by the lens barrel.
* Vignetting may occur at 18mm or shorter focal length, and at 0.6m or shorter shooting distance.
* We do not recommend the use of DX NIKKOR lenses with 35mm (135) or IX240 format cameras
