Download the A77 ISO3200 ARF file from Imaging Resource:

take also the one from the G3:

Feed them both to a good RAW converter (I used RawTherapee, ignored the messed color profiles and corrected for WB) and take a good look!

There is absolutely more noise on the G3 (I'd say at least 1EV disadvantage) but there is absolutely no detail advantage on the Sony and sharpness is also better on the Panny.

Bear in mind that these aren't final production samples, so IQ might still improve and don't forget that the NEX-7 should have around an extra 1/3EV advantage.

Two conclusions to draw here:

  • G3/H2's 16MP has plenty of detail to go against Sony's 24MP.

  • Sony's JPEG engine performs an unbelievable massacre on detail and textures. Shooting RAW is mandatory!
