Help me to decide a compact small camera...

Undecided between; Sony NEX, Olympus EP Series, LX-5, GF1/2 etc....

Already have a DSLR just that some occasion is not apropriate to bring a DSLR and sometimes I prefer to bring a smaller one easier to bring around.

Budget wise below 2.5k the better.

Ohh shit am having tough decisions deciding on either;

Pana GF1 20mm f1.7 (amazing bokeh with this lens)
Sony Nex5 or 3 with its limited range of lens
Olympus EP1 or EPL1

Am already a DSLR user, just want a smaller than DSLR to bring around when there are places its unapropriate to bring a DSLR.

But the Pana GF1 20mm f1.7 lens is very tempting amazing bokeh pictures with that...

What you mean by background de-focus? Is it a software done in the PC or its a function in the camera after snap it will de-focus?

SONY NEX seems to gain my interests....now my next question is should I go for Nex 3 or Nex 5 since the diff is only on the 1080i video recording and the build quality. And also the type of lens I should go first?

I know with $ anything is possible but I'm trying to keep it as low as possible looking around below 2.5k

Btw any installment usually from SONY?

Dual lens kit means two lens?

Ohh damn after reading alot on Sony NEX it seems that Nex-3 is also not a bad choice and apart from being polycarbonate body, the price is affordable for dual lens too.

So now my concern on Nex-3 is that, how is the build quality for those heavy users out there?
