Just been testing a little in the living room with low light, and that do not seem to have become better, still quite noisy.
I will have to side with DM on
For me it all started to go downhill when the dual frame WDR (HDR) was abandoned
I cant remember that far back for sure, but it is something like that.
M2 daytime footage compared to the V3 GC and the XS is like it have a Russian industrial filter on it, colors are so much better on the 2 SG cameras and the M2 is like its filmed thru a really dirty UV filter.
The colors do appear true but they are not as vibrant as on the SG cameras, almost like i am filming thru a window with some degree of tint on it.
Now the M2 is no way near as good in low light was it once was, its like it have lost 2-3 ISO steps, and if i don't use WDR then it is more or less just blackness.
I remember when i first got the M2 it was actually more light sensitive than my old 9665GC, that's far from the case now even factoring in i am on a V3 9665GC now.
I have been toying with strapping the M1 to the M2 in the windscreen to demo the difference between the 2, and i really think the M1 will perform much better in low light.
The recording i madw of my flashlights tonight using the GC i wanted to upload the M2 footage of the same, but in the M2 footage you cant even see the dlg building 100 M away though it have a lit street below.
At least on the GC footage you can see the outline of the building before i crank up my flashlights, on the M2 ( footage deleted in FW update ) the building are just darkness aside the a narrow band down low where the street light is.
