Personally I put handling and features before IQ, simply because cameras have for a long time exceeded my requirements for IQ. I take it for granted that any new camera will be fine in that respect and if there is a small improvement over an already excellent IQ, then that's a bonus. :smile:Honestly I don't know how everybody choose their camera and really don't care about that because everybody is free to choose whichever way they like best. What I care is how I choose my camera and handling is important but doesn't say anything about IQ which for ME is the most important thing I consider when choosing a camera; so if IQ seems to satisfy my needs then I try handling and ergonomics BUT if I think IQ is not up to what I need then I wont even try to handle it.
With the GX7 at this time handling is impossible because it's not available in shops so we can only try to understand how the IQ is from those who are lucky enough to be able to test it. It's possible that someone chooses a camera only from reviews and spec sheets.
