Using the Digital Lens Optimizer
This function enables the resolution of images to be increased by 
removing any remaining aberration related to image-forming capability 
or any deterioration of resolution resulting from diffraction phenomena 
that are unavoidable as long as light must pass through the lens. These 
optical phenomena cannot be corrected under [Lens aberration 
correction] 
. Correction is achieved using the designed value of 
each lens. The images that can be corrected are RAW images shot 
using any of the following “compatible cameras” and “compatible 
lenses”. JPEG, TIFF, S-RAW, and M-RAW images cannot be corrected. 
To use this function, [Lens data] for the lens used to shoot images first 
needs to be downloaded to your computer.
Before using the Digital Lens Optimizer, it is recommended that you set 
[Sharpness] or [Strength] for [Unsharp mask] for images to 0.
