Lens Aberration Correction Chromatic Aberration Correction Chromatic aberration (color fringing around subjects) can be corrected. zz[Chromatic aberr corr] is not displayed when [Digital Lens Optimizer] is enabled. Diffraction Correction Diffraction (loss of sharpness caused by the aperture) can be corrected. zzDepending on shooting conditions, noise may be intensified together with the effects of correction. zzThe higher the ISO speed, the lower the correction amount will be. zzFor movie recording, [Diffraction correction] will not appear. zzWith "Diffraction correction", degraded resolution due to the low-pass filter, etc. is corrected in addition to diffraction. Therefore, correction is effective even at an aperture close to the open aperture. zz[Diffraction correction] is not displayed when [Digital Lens Optimizer] is enabled. 133
