Like I just said in another thread.. It all comes down to our DOF
preferences, doesn't it? If you like the very shallow DOF that f/1,4

  • f/4 gives you on FF, then FF is the way to go, but if you prefer a

deeper, more 'normal' DOF, then FF won't necessarily give you better
IQ. If you're shooting at for example iso400, f/8 on FF, then a 2x
crop camera would give you just as good IQ at iso100, f/4.

Sure, with ideal cameras, but the fact is, the 2x-crop sensors
currently available all have much higher read noise, especially at
high ISOs. The "noise equivalence" concept only applies to photon
shot noise.

Haven't seen any tests yet, but the GH1 sensor seems promising.
