I think the issue deserves a separate thread, so I moved my post here. I took the same pictures with the same parameters before and after firmware upgrade. From 1.2.1 to 2.0. This is the minimum to be para-scientific. Please do some more and try to participate in the blind test below.
I am also curious about the "noise reduction" message/countdown with shutters longer than 2 sec. Any explanation of this?

The moved post:
I am new to M8 (third day, bought used) but also tried some quick and dirty comparisons for high ISO noise before and after FW update.
I took some pictures through my living room onto the dark dining annex. The lights were three floor lamps and one ceiling with "old fashioned" 60 W bulbs. These bulbs imitate the early 20th century electric lighting, they are dim and very warm. There is also a burning fireplace (damn cold September!). We like our lighting really low for a glass of wine and good jazz. So yes, by all standards it's really dark yet contrasty. A,B, C raw originals were given only auto WB and auto development in Lightroom2. The camera AWB chose 3200K, the Lightroom 2800K.
The three pictures A, B, C are same ratio (appx 1/3) crops of the full M8 frame and were taken with camera resting on a chair+release cable, with:
1) Ultron 28mm; 1/8 sec; f2.0; ISO 2500; firmware 1.2.1
2) Ultron 28mm; 1/8 sec; f2.0; ISO 2500; firmware 2.0
3) Summicron pre-asph 50mm; 0.7 sec; f5.6; firmware 2.0
Match A,B,C to 1,2,3 please.
I also found out an intersting phenomenon when shutter was 2 sec or longer. After taking picture the LCD displayed message "Noise reduction" and counter went down 2 sec, 1 sec...Is this new? I could not find anything like that in any literature.
D is the original untouched DNG photo. Guess:before or after fw update?

Disappointed? Well I offer you truth, the whole truth and only truth. The purpose of the excercise was comparison of noise, not a pulitzer.
