DX Lenses
DX lenses are designed for use with DX format cameras and have a smaller angle of view
than lenses for 35mm format cameras. If Auto DX crop is off and FX (36Ч24) 1.0Ч (FX
format) is selected for Choose 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.
