Adobe Camera Raw 5.2 versus DxO Optics Pro 5.3 - Part I - Chromatic Aberration - Additional Crops
Crop
                   A - B - C - D (100%)                                             E (200%)
JPEG image as it came out of the camera
The cropped areas clearly show chromatic aberration (CA) and moiré.
RAW image opened with ACR Default settings
Opening the image with ACR default settings results in moiré being removed.
RAW image opened with ACR CA removed
After sliding the Chromatic Aberration sliders in the Lens Corrections tab to the following positions:
Fix Red/Cyan Fringe -35
Fix Blue/Yellow Fringe -14


All CA is removed and no new artifacts are introduced.

RAW image opened with DxO - Default CA settings
Image processed with DxO in default CA settings (Intensity 100, Size 7, Lateral CA enabled) results in undesirable partially desaturated halos and only partial removal of CA but makes CA worse in the foliage. The gold of the towers is becoming desaturated. See also crops on the previous page.
RAW image opened with DxO - Maximum CA settings
Sliding the Intensity and Size sliders to their maximum improves things but still does not completely remove CA. Moreover, the towers are now a major problem area as it has become completely desaturated and there is a gray "halo".
Conclusion
DxO Optics Pro 5.3 claims that "Aberrations are corrected by lens/camera specific modules, ensuring laboratory-grade precision without user intervention". While this sounds great on paper, when testing this with an image shot with a Canon EOS-1Ds Mark III, DxO was unable to remove the CA, neither with the default settings (i.e. no user intervention), nor with the maximum settings, despite using the lens/camera-specific DxO module for Canon EOS-1Ds Mark III with EF 16-35mm 1:2.8 L II USM lens.

It is hard to improve on the ACR result. Only the moiré was comparable to ACR (although on close inspection a bit more color moiré remains in the DxO result). The DxO CA results are vastly inferior to ACR and if you improve things in one area, other areas become totally unacceptable.
