Precautions on close-distance scale
(For DA 16-45mm f/4ED AL, DA18-55mm f/3.5-5.6 AL)
In the close-distance scale range (the distance scale in the orange area), when shooting at
the maximum aperture, image quality deterioration in the picture corners may result
because of the optical characteristics of the lens.
When taking a picture in this range, we recommend that you use a smaller aperture,
stopping down from wide open.
