The new Olympus E-M10II matches and perhaps just very slightly improves upon the noise shown by a D7200 Nikon. Both however are still noisier than Samsung's NX-1 with its BSI sensor.

You think so?
You don't think that the fact that the Olympus camera needed more than
1/2 stop greater exposure time to get the same exposure at f5.6 with the
same studio lighting on DPReview's test has some bearing on the result
that you think you're seeing?

Are you talking about the -0.33 stop exposure bias value in the D7200 shot?

No - exposure bias is just a metering setting.
I'm talking about how when set at ISO 200 and f5.6 under controlled
lighting, the Olympus camera needed an exposure time of 1/60th to
achieve an approximately equivalent exposure. It looks like ISO 200 on
that Olympus camera is overstated.

Yes, I didn't look at that. I was looking for visible noise so I looked at 1600 ISO. The exposures for the Nikon and the Olympus were identical. What this really means is that perhaps Nikon could release a FF camera with a higher megapixel count, like at least 64mp or 80mp for those who don't care if there is visible noise above 800 ISO.

When I looked at ISO 1600, that's what I saw.
Compared to the D7200, the u4/3 looks lousy.
