DXO flow / lens correction thread?

Hi all,

I recall a short time ago someone posted their DXO settings for lens correction, I think it was for their K10D -- anyone recall the thread? The posting had dramatic before and after shots and the results were quite impressive (removed CA, barrel distortion, etc).

On a related note, tonight I was comparing the DPReview RAW studio shot of the K20D vs the Canon 5D & 5D MK II:

K20D: http://a.img-dpreview.com/reviews/PentaxK20D/Samples/Comparedto/pentaxK20D_ISO100-acr.jpg

5D: http://a.img-dpreview.com/reviews/CanonEOS5DMarkII/Samples/Compareto/Studio/...00-raw-acr.jpg

5DMK2: http://a.img-dpreview.com/reviews/CanonEOS5DMarkII/Samples/Compareto/Studio/...ISO100-ACR.JPG

Two things I noticed, the K20D has Canon beat in-terms of wall detail and sharpness on the Queen of Hearts card. I think the K20D might have a weaker AA filter, since both Canons should have equal or better resolving power.

A strike against the K20D if you look at the edge of the Martini bottle in the Pentax shot you can see what looks like CA or a second shadow on the bottle -- the effect is not as pronounced in the Canon shots.

I'm wondering out aloud if that's a lens limitation or sensor/camera issue.
