I haven't read through this whole thread, so I don't know what was previously discussed, but I've found the default lightroom sharpening to be too agressive... accentuating high-iso noise. Also, under Camera Calibration

rofile, try Camera Faithful or Camera Neutral...it may give you a better rendering than Adobe Standard depending on what you are going for. Let me know if any of that helps you out. I'm genuinely curious.
Thanks for the info. I tried the Neutral/Faithful profiles and they didn't do much to alleviate the noise. As you said, Lightroom's Standard noise level (25) is far too harsh, and I had better results when dragging the Sharpening slider to '0.' There was still a bit of noise left when compared to the raw file in DPP.
Digital Paradise, I love the photo of the dog shot @ 1600 ISO. You mentioned applying no NR for this photo. Do you mind me asking which program you ran it through, or was it straight out of camera?
I'll post a comparison of a LR photo and that same photo in DPP later this evening/tomorrow to show the difference I'm getting. As mentioned, I'd love to find a way to mimic DPP's effects directly in Lightroom. However if I have to, I suppose I'll just add DPP as the precursor step to Lightroom in my overall workflow, to alleviate the noise.
I'm curious, has anyone with a 5D3 + LR noticed this (Seeming) software problem? Or is it just a few?
