Nikon D3X ADX Lenses, AThe Viewfinder Display

ADX Lenses

DX lenses are designed for use with DX format cameras and have a smaller picture angle than lenses for 35mm format cameras. If [Auto DX crop] is off and [FX format (36 × 24)] or [5 :4 (30 × 24)] is selected for [Image area] when a DX lens is attached, the edges of the image may be eclipsed. This may not be apparent in the viewfinder, but when the images are played back you may notice a drop in resolution or that the edges of the picture are blacked out.
