I noticed something in a few pictures and looked into it further using different raw processing software on M8.2 pictures. What I was noticing is that detail was looking mushy in some pictures and I thought it might be the lens, but now I see it is how C1 processes by default.
When you open a DNG file, C1 has the following set by default on the details tab:
Noise Reduction
Lunimance: 25
Colour: 40
Sharpening
Amount: 130
Radius: 0.8
Threshold: 1.0
It is the luminance noise reduction that is making much of fine detail turn to mush, and it is not really needed at ISO160 anyway.
Here is a 100% crop of a picture taken at ISO160 that was processed using the C1 defaults as listed above:
Here is the default NR settings but with sharpening set to 190/1.3/1.0:
Here is the same area cropped but with Liminance set to 0 and sharpening set to 190/1.3/1.0:
The detail is much better and has not been destroyed by the default NR. I suggest turning off the Luninance NR unless it actually help for high ISO shots.
I know it is hard to tell with such small samples, but give it a try and you will see the difference. I can report that Aperture and RPP do not cause this mushing of fine detail as they do not set NR by default.
