gbdz: Two days ago I tried the DxO RAW converter for the first time. It has a clear advantage of producing less noise than the Lightroom. The difference is really noticeable. This while I am sort of getting impatient with the noisy shadows of the 5DIII. Within the next year I think I will get a Sony 7RII or, if Canon manages to create a replacement for the 6D...what a magic word, 'IF'...
if you havn't got it, download , DPP4 ver 220.127.116.11 thats for windows, for apple ,its 4 something , look its there, you will need camera body serial number and its yours , better than adobe for handling noise.
It maybe a very good lens, but at Aust$4000 I think you would need to find a real need for it. or deep pockets maybe.
I was using photoshop 3 about 20 years ago,
