A very interesting comparison here: ISO WARS: The Olympus E-P3 vs The Sony NEX-5! | STEVE HUFF PHOTOS Two conclusions for me: 1) My comfort zone for color has moved up from 1600 to 3200 in some situations - can't wait for the RAW converters to finalize. 2) Based on his examples I have a new Myset: B&W! The B&W shots (Monotone, not Grainy B&W) at ISOs up to at least 6400 are great IMHO. Reminds me of B&W film. Tho' I would like even higher ISO performance, I'm very happy with what I have.
