Originally posted by Big G Sorry this post is just what I've come to expect on these boards; unsubstantiated talk. If you can provide detailed tests backing up your claims, lets see them. I have access to two K20D bodies and both exhibit the same noise levels. DxO numbers are just .... numbers. I'm providing test images.
No need to be sorry, we're just discussing your test results. I can't do the comparisons without a 7D. I do have a K20D and it's never produced such ugly ISO 1600 files, even with NR turned off. I've read raw noise tests on the K20D, K-7, D300S and 7D, at DPR and DXOMark, and your results don't correlate. So who should I believe, Some Guy On The Internet trying to show the 7D is superior, or my own observations plus professional testing? I don't blame you for being pissed that Ogl said the K20D was so much better, but everything I read says the K20D and 7D are neck and neck for high ISO performance. That is clearly not what your images show.
Originally posted by Big G Did you not read that I said the NN profiles was set to "0" for luminance and "0" for colour? This is minimal noise reduction, I could apply a lot more to both files to clean them up more; but to repeat myself yet again, this was to show high ISO noise, not the effectiveness of Noise Ninja and not the in-camera noise reduction of the bodies. It is RAW sensor output, so your "I use weak and it looks better" is a moot point as we are not testing in-camera NR.
I read this;
"Noise Reduction and sharpening applied in Noise Ninja". There's not much point in doing your own noise reduction if the camera can do a better job. I suggest that just turning off NR in both cameras would be a better representation than a random tweak in Noise Ninja. I have some test photos in my hard drive that were taken at 1600, 3200 and 6400 with the K20D and NR off. Your ISO 1600 file looks worse than my ISO 3200 file. I can post them for you this evening if you like (I'm at work now).
In looking at your results, I suspect you missed focus with the K20D. As everyone knows, the K20 AF does not do well under tungsten light. There has to be some explanation for the way these files look.
