Preparing the Camera
38
• When peripheral illumination correction is activated:
- Depending on the recording conditions, noise may appear in the periphery of the image as a result of the
correction.
- The level of correction will be lower for lenses that cannot provide distance information.
- The level of correction will be lower the higher the ISO speed/gain setting used.
- Due to the difference in sensor size, when using EF-S lenses, peripheral illumination fall-off may be more
pronounced.
