Peripheral Illumination Correction
Depending on the characteristics of the lens used, the image around the corners of the picture may seem darker
due to light fall-off or peripheral illumination drop. If the camcorder has correction data available for the EF lens
used, it can apply this correction data to compensate as necessary.
1 Attach the lens you want to use.
2 Open the peripheral illumination correction screen.

• If correction data is available, the lens model name will appear on the
screen.
• If correction data is not available, [Periph. Illum. Corr.] will appear
grayed out. Visit your local Canon Web site and check if there is
correction data available for the lens you are using. If so, download the necessary update package and
upgrade the camcorder’s firmware following the instructions supplied therein.
3 Select [On] and then press SET.
• As long as [

the appropriate correction data.
NOTES
• About lens correction data:
- The camcorder contains a register of correction data for compatible lenses that were available at the time
the camcorder went on sale. Correction data for future lenses will be made available as part of the regular
updates released for the camcorder’s firmware. For more details, visit your local Canon Web site.
- 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.
