DS Coating and DS Effect
Other Shooting Precautions
z
• Compared to the RF85mm F1.2 L USM, the effect for improving loss of light around the edge of
the lens is diminished even when the lens is set to its lowest aperture.
(not applicable when Peripheral Illumination Correction is used)
• Since the amount of bokeh is less than that offered by the RF85mm F1.2 L USM lens, depth-of-
field will appear deeper in shots taken with the DS lens.
• If you look inside the lens from the front, the surface with DS coating will appear iridescent or
you may see a round pattern in the center. However, these factors do not have any negative
impact on shooting.
