As far as tracking is concerned I wouldn't really call this hard data.
However, the Sony SLTs are "good" here already so there's no reason why the Gs should be any worse.[/quote]
But the SLTs are phase AF like SLRs. I'm all for accurate AF, but the other side is speed and tracking accuracy before you can start to think about retiring SLRs. I'd love the Panasonic contrast AF speed even, but I'd rather have it in a Canon or Olympus body... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

Like the old saying "use the right tool for the job". Panasonic contrast AF speed is excellent, but it is a long way from replacing a DSLR in all applications.
An interesting note on the Panasonic web page, they say the AF is faster as they are sampling faster. I wonder if that would simply scale to DSLRs also. I assume they work in live view/video mode, perhaps up to 60fps, but if the sensor were designed to work at higher framerates, that could help improve contrast AF speed on them too?
