I've been whining for a while all over the forum, so to speak, about the need for faster, more acurate AF system, and it looks like we may have what we wanted.
Of course, I've also whined about high ISO performance, and that seems to have been solved as well.
These two features alone are enough for me to make the move to the K5, remains to be seen now which of the two cameras I will keep: my K20D or my K7.
imthe guy ... ISO means you will never have to worry about it for shooting birds!
There is indeed much more than that in the K5, we (I) have to wait and see what reviews and tests will provide.
