NOTES
• About using an EF-S lens (both camera models) or compatible EF Cinema lens (j only): This camera’s
sensor is larger than the sensor size for which these lenses are designed (APS-C or Super 35mm).
When using these lenses with the camera, you may notice peripheral illumination fall-off or
vignetting. To prevent this, you can use the [Camera Setup] > [EF-S Lens] setting to change the
sensor area that is used for producing the image. This setting digitally enlarges the image by a factor
of approx. 1.55 (j) or 1.04 (i) so the image quality will deteriorate.
• Depending on the lens's characteristics, the corners of the picture may seem darker due to light fall-
off or illumination drop. You can use the [Camera Setup] > [Periph.Illum.Corr.] setting to have the
camera compensate if it has the correction data available for the lens.
• If you are using a compatible lens*, you can use the [Camera Setup] > [Zoom-Iris Correct.] setting
to have the camera adjust the aperture while zooming.
* Some EF lenses and EF Cinema lenses are not compatible with this function.
