Agreed, but I perhaps wrongly assume that the in camera processing for optical distortion and chromatic color aberration are programmed to the lens and may be more easily done by the camera than in external software, depending upon the type of post processing software one owns or uses. Also, it does allow one to look at the jpeg in camera and see the approximate results. As I understand it, with these features, a separate file is created which can then be applied to the RAW image outside of the camera.

I am somewhat "playing devils advocate", because I do see both points of view, and I think it would depend on someones workflow and comfort with external software.

Thanks for responding.
