3 Correction of Lens Peripheral Illumination and Aberrations When distortion correction is enabled, the camera records an image range narrower than that seen through the viewfinder. (Image periphery will be slightly cropped and resolution slightly lowered.) If you set [Distortion] to [Enable], the maximum burst (p.153) during continuous shooting will decrease. Distortion will not be corrected if you shoot a movie or set the HDR mode, multiple exposures, or Multi Shot Noise Reduction. Using distortion correction during Live View shooting will slightly affect the angle of view. When you magnify the image during Live View shooting, distortion correction is not applied to the image displayed. Therefore, if the image periphery is magnified, a part of the image range that will not be recorded in the actual image may be displayed. Dust Delete Data (p.407) will not be appended to images recorded with distortion correction enabled. Also, the AF point(s) will not be displayed (p.359) when you play back the image. Lens Correction Data The camera already contains data for lens peripheral illumination correction, chromatic aberration correction, and distortion correction for approx. 30 lenses. If you select [Enable], the peripheral illumination correction, chromatic aberration correction, and distortion correction will be applied automatically for any lens whose correction data is registered in the camera. With EOS Utility (EOS software), you can check which lenses have their correction data registered in the camera. You can also register the correction data for unregistered lenses. For details, refer to the EOS Utility Instruction Manual (p.536) on the Software Instruction Manual CD-ROM. 183
