Hi,
Can anyone tell me how KP and K-1 autofocus speed and accurate compares?

Cheers

The K-1 has a newer AF system but for all practical purposes the perceived accuracy should be the same. The KP has slightly better tracking, on par with what's in the K-1 II. The bigger consideration will be the format difference.

F2.8 accuracy on the K-1 means one stop less DoF (at equvivalent focal lengths). Both are F2.8 accurate with the center points. The 4 additional focus points are very usful on the K-1.

Ok, so no huge difference. Thank you for the information

I own both the K-1ii and the KP...I have taken photos simultaneously and I believe there is no discernible difference. With both cameras sporting the latest firmware, I can say that the K-1ii is a nano second faster, but the KP is excellent and only 2/3rds the size and weight. To me, the sharpness of the K-1ii is a bit better, but I'm not sure if that has to do with the newer generation sensor/AF or simply the difference between 24mp and 36mp file sizes.

I own the KP and the K-1. I find the AF on the K-1 to be a bit more decisive. Otherwise, I can find no discernable difference.
