22 Precautions on close-distance scale (For DA 16-45mm f/4ED AL, DA 18-55mm f/3.5-5.6 AL WR, DA L 18-55mm f/3.5-5.6 AL) In the close-distance scale range (minimum focus distance range), when shooting at the maximum aperture, image quality in the corners of the picture may deteriorate 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 full aperture.

Precautions on close-distance scale
(For DA 16-45mm f/4ED AL, DA 18-55mm f/3.5-5.6 AL WR, DA L 18-55mm f/3.5-5.6
AL)
In the close-distance scale range (minimum focus distance range), when shooting at the
maximum aperture, image quality in the corners of the picture may deteriorate 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 full aperture.
