Originally posted by frank As I said above, the camera is just a prototype, and the firmware is only v0.33, we can't say if the final product would perform the same.
But since K-01 is still using screw driven AF mechanism, contrast detection AF is pretty much the same as K-5 in LiveView, AF speed is more or less relied on the lens mounted. Don't expect big AF speed improvement over the old cameras unless Pentax change its lens AF system.
I had the impression that its faster than on the K5 to be significant and considered an improvement for LV AF, but you have the camera in your hands to know better.
For those who asked, there is no quirky zoom in type AF like on K5. Very normal CDAF like all CDAF type cameras.
I'd put it somewhere around GF1 type AF for this very early version on firmware (as mentioned by Frank)
So for those familiar with m4/3 cameras, based on my unscientific guard-feel, AF speed is certainly much better than EP1/2 (which was a joke) , around that of GF1 (which is considered fast and good enough) but slower than EP3/G3 which sets the standard for CDAF.
Remember VERY EARLY FIRMWARE, so don't base anything on this observation.
