This allows DxO to understand the "flaws" of each lens, at different focal lengths, focus distances and apertures. What DxO has always done is to test lenses and develop a performance profile of each one. I have upgraded DXO and am quite impressed with "DETAIL > Noise reduction - RAW" (high ISO) function and "DETAIL > Lens Sharpeness."
