Thank you everyone for your quick feedback on this point.  The LR sliders are all at their defaults and these screen grabs were immediately after the "import" in the history.  I was thinking that DPP would also have been a "raw" image rendition without the extra softening / noise reduction, but it seems that this might have been an incorrect assumption.

I recognize that the lighting test here is a tough one, but the intention was really to evaluate the high-ISO performance of the T2i versus the 6D.   I did not conduct the detail tab changes in LR and did not export these to a JPG for comparison, and will try that this evening for testing purposes.

Maybe I am wrong here - but I was really expecting the 6D to have much less noise than the T2i - but I really don't see this as the case in these examples.  Ultimately, if I am starting with similar noise both from my T2i and from the 6D, I would expect similar end-result jpgs (again, I could be wrong with that assumption!).

Note that the T2i was maxed-out in the Auto-ISO setting at 6400 and hence the reason that the image is a little darker than the 12,800 (wow!) ISO of the 6D.

My thoughts are the increased NR with LR will reduce the crispness of the vertical lines on the right of the image, although these seem quite good in DPP.

Thanks again for your comments.

Here is one more example....

Another image:
(1) LR4.3
(2) DPP
(3) JPG processed in the 6D

The JPG is much closer to the DPP image than that of LR.

Thanks for your thoughts.... maybe I should have posted this to the software forum?

I am attaching 4 images:
(1) 6D in DPP
(2) 6D in LR4.3
(3) T2i in DPP
(4) T2i in LR

While there is definitely a difference in the quality of the difference in IQ from the T2i to the 6D, this really punches through with the DPP converter as compared to the LR.

I have been shooting with a Canon T2i since they rolled out and started RAW shooting shortly afterwards.  I purchased LR3 (at the time) during one of the Adobe one-day sale and have been sold ever since.  That is, until I just purchased a Canon 6D as what I would see as a great upgrade.

Almost every reviews of the 6D is stellar and I was ready for better low light shooting, etc. that the full frame would provide.  I have been running LR4.3 since it was released in mid-December.  Although there is a difference in LR between the T2i and 6D, the differences are not significant at all.  I am shooting the same f-stop, same ISO, same shutter speed and look 1:1 in LR.  I've tried the T2i with my 18-135 EF-S and with the new 24-105L with similar results.

I decided to try DPP for the RAW and was greatly impressed with the results as compared to LR.  Huge difference with my test shots.  These shots are tough - night time on my back deck with a fresh snowfall and with floodlights on.  Shooting as high as 10,000ISO with the 6D and 6400ISO with the T2i.  I've also tried the same shot with a 580EXII on each and results are again not significantly different in LR but quite different in DPP.

I tried RAW+JPG and the JPG is almost identical to the shot in DPP.  LR remains very grainy and I can reduce this with the Details slider but with the obvious loss of detail.

Just wondering if others have seen this?  Opening each image in DPP, saving it and then importing to LR would be tedious and time consuming.  I could shoot more in JPG but this is not my desire - at all.
