Is it done using MFNR preset?Do I see horisontal noise banding?
Anyway, looks very decent for ISO12800
I downed the shot in 2500 ISO with the woman sitting on the table, look at that one in full size, i do not think that there is something to be proud about it. I get that quality at 3200 ISO with the NEX-7 too with the same light conditions
Sorry dude. Your parents should not be proud of you as well. No one stated it will be noiseless. No camera is at such a high sensitivity.
Those shots look clean, those that Steve Huff shows too, those form Imaging resource look crappy. How come, good question?
Steve Huff has a photo from pretty much the exact same angle (slightly later in the evening), and some more impressive high-iso shots (better compositions in general IMHO). Even 25600 looks surprisingly usable.
They might be useable if you downsize to any format around 20x30 cm, but not in full size. In good light conditions, shots like the 12500 ISO billiard balls are perfectly useable, but look the picture of SF in the Night at same value and discover the destruction made by the noise reduction in camera. I doubt not a moment that with RAW and a good PS plugin like Imagenomic or Noise Ninja, you are able to make a perfectly useable shot out of such a picture. The result is quiet stunning anyway, despite the lack of sharpness of the lens all over. One needs to wait for shots made by people with the full knowledge and know how, and then we can get a concrete view of what it really can do.
Lots of detail here for a high ISO with less noise than I would have expected.
