Doh ... think about it for just one second. That AF system is in my GX-1S and the K100D yet the K10D focus' faster than them. Some of it is related to the torque and speed of the motor doing the focusing which will be in turn affected by the power source eg My GX-1S focus' faster with CR-V3's than it does with NiMh - well at least the motor sounds like it is turning faster and it appears that other forum posters have come to this conclusion
Not only that by I defy anyone to be able to get the same times down to a hundredth of a second from the same camera let alone different cameras !! It just isn't scientifically probable !
