Ooo, thanks!
This test, I was trying to balance the camera shake (see how low shutter speed I can go) and also the noise in the high iso. Would like to get you guy's opinion on which picture among the wide that you guys like the best?
For me, the wide one, I can't seem to detect any motion blur, on the iso 100 picture, even though it is at 1/10 sec.
For the zoom one, its hard to choose between the iso 400 and iso 800, iso 800 seems to have less motion blur but the color is worse.
Comments Welcomed.

The general photography rule of thumb for shutter speed is that it should be 1/effective focal length.
For example: if shoot widest 28mm, then by right the minimal shutter speed to avoid shake is 1/28sec.
However, since XZ-1 has a compact sensor and kungfu image stabilization... hence you (depending on individual.. whether got drink coffee, wank, parkinson or smoke etc

) can use a far lower shutter speed than that.
But the concept remain... the further you zoom, the faster the shutter speed you need to minimize blur due to shake.
Blur from moving subjects is another topic altogether.
As for ISO...
ISO 100-200 --> No significant real difference in everyday use
Up to ISO 400 --> Noise creeping up and colors starts to go.
Anything above that is really details vs noise... choose one.
Personally I always try to keep within ISO200 and worse case scenario ISO640 for really difficult shots.
This one is ISO640.... Warning: Non Halal dead thing picture
