DX Lenses
DX lenses are designed for use with DX format cameras and have a
smaller angle of view than lenses for 35 mm format cameras. If Auto DX
crop is off and an option other than DX (24×16) (DX format) 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.
