These are from the XZ2. The same pics here are 6400 and 12800 ISO. You don't even need to open them to know they look like crap. But my question is, why take that shot at f/4 1/1000s? It seems you could gain 3 stops by slowing down to around 1/120s, and another 2 stops by shooting at f/2. Wouldn't this put it around ISO 400-800?

Even at three stops, F2 vs. F5.6, the X-A1 will beat the XZ2. Stops go like this, F2, F2.8, F4, F5.6, F8 so three stops would be iso 800 vs. iso 6400. On top of that, you will be able to pull more out of the shadows with the X-A1 because it will have considerably more dynamic range than the XZ2.

XZ2 is f/1.8 to 2.7, X-A1 is 3.5-5.6, so that is about 2 stops at either end.  Sensor is about 3 stops smaller, but DXOMark puts it only about 2.5 stops behind, so they are going to be fairly equivalent if you aren't shooting at base ISO.

Meaning the dynamic range at 800 on the XZ-2 should be fairly comparable to the dynamic range on the X-A1 at 3200+.  Since the aperture is 2 stops larger it means for how you can shoot wide open on either they should perform fairly similar, the samples on this site in the studio comparison tool seem to back that up fairly well.

Obviously the smaller sensor will be at an overall disadvantage, but the camera is also much smaller which could be considered an advantage to some.

I shoot at base ISO 70% of the time so much prefer the larger sensor.  The aperture size is no longer an advantage here.
