• Diffraction correction ( ) The diffraction by the lens aperture degrading the image sharpness can be corrected. If [Enable] is set, the corrected image will be displayed. If the effect is difficult to discern, magnify the image ( ). Caution Processing RAW images in the camera will not produce exactly the same results as processing RAW images with Digital Photo Professional (EOS software). If you perform [Brightness adjustment], noise, banding, etc. may be intensified with the effects of adjustment. When [Digital Lens Optimizer] is set, noise may be intensified together with the effects of correction. When [Digital Lens Optimizer] is set, image edges may be emphasized, under some shooting conditions. Adjust sharpness of the Picture Style as needed. Processing with [Digital Lens Optimizer] set to [High] may take some time. Note Effects of lens aberration correction vary by lens and by shooting conditions. Also, the effect may be difficult to discern depending on the lens used, shooting conditions, etc. 513
