I have not really answered your question properly. I am a DxO convert. I stoped using Adobe Camera RAW about 14 months ago. I find that the RAW conversions with DxO are superior even to ACR 5.7, even in Default mode. DxO is excellent at correcting Lens Distortions and for Keystoning. The dedicated camera and lens Plug-In's are possibly the reason why. Can send you a "Get Started" methodology that I have written for others over on flickr. e-mail me at bajanexile@aol.com
