For details, refer to the EOS Utility Instruction Manual. zzDepending on shooting conditions, noise may be intensified together with the effects of correction. Image edges may also be emphasized. Adjust Picture Style sharpness or set [Digital Lens Optimizer] to [Disable] as needed before shooting. zzThe higher the ISO speed, the lower the correction amount will be. zzFor movie recording, [Digital Lens Optimizer] will not appear.
