When you were one of the only people having a problem, people were not too thrilled about claims that the K-3 was a bad camera... That was really the only problem.

I would do a complete factory reset and start over. Turn the HIgh ISO noise Reduction off and turn the AFA to AF-s and see where your at.

I bet your photos improve dramatically.

No, they won't. Here's a sample.

I've turned High ISO Noise Reduction to Auto. I've turned Slow Shutter Speed Noise Reduction to Auto. I never have my camera set to AF-A. I've set my camera to the Custom Image settings suggested by David Tittermary. I never fully believed your assertion about the noise reduction being the problem (or possibly ANY problem) but was hardly in a position to argue a case, but now I'm getting close. Time will tell. In the meantime, have a look at the image below, shot at 6400 ISO with NR set to Auto. Shot in a reasonably dark corner of a shed. I opened it in ACDsee and applied a little NR then resized it for here, otherwise it's as taken. Enlarge it to 100% and see if you'd be happy with it had you taken it?

Can you tell me here what settings to use to replicate the problem you were getting with aggressive NR? I'd like to try it from scratch.

I don't believe anyone has posted a photo that replicates Qwntm's result with the blur from auto ISO noise reduction. Qwntm says that is because only a special kind of flat lighting activates the high level of NR. On the other hand there have been many photos posted that like yours do not exhibit the problem. Turning high NR on and off shows high NR will degrade the image, but apparently no one else has knowingly had auto NR trigger high NR And told us about it.

So there is no doubt that if auto NR activates high NR sharpness will suffer. The question that remains unanswered is exactly when and how often does auto NR actually activate high NR. It is actually a moot point now here at DPR anyway, because everyone within earshot of DPR has turned off auto NR.

By the way, I am glad that high/low key suggestion was helpful.

Yes, indeed, from David's rabbit picture thread? I was already thinking along those general lines after Andrew tossed out the bit about the bright areas clipping. There really are a plethora of controls and fine adjustments to think about and test.
