Hopefully not derailing the thread here:
I have a very similar compact camera to the J1 of rorz0r (i.e. the V1). Recently I took an interest in how usable this would be under low light conditions. The theory is that one can achieve the desired depth of field at a far lower f-stop on a small sensor than on a larger sensor. In other words it would be necessary to stop down the lens on an SLR and go up a few steps in ISO to get the same result as with a compact camera. The SLR should still win in image quality, but not by as large a margin as would be expected.
Below is a shot that I took outside a petrol station a couple of nights ago with the V1 to test this idea. This was hand-held using a 50mm equivalent lens at f1.8. Even at this aperture there is a good DOF. The photo is not as noise free as one that an SLR would give, but it is still usable. The point is that a reduction in sensor size does not automatically equal a similar reduction in quality.
