The Digital Lens Optimizer is a feature that takes image data captured in RAW mode and eliminates the differences between the actual data and ideal optical characteristics. It is incorporated in the Digital Photo Professional application bundled with the latest EOS digital cameras. Compensation provided by the Digital Lens Optimizer includes not only lens aberrations but also the diffraction effect and changes introduced to the light by the low-pass filter and other parts. This groundbreaking approach uses highly sophisticated technology to enable a further significant improvement in image quality.
