Ok fellows,
I went back to the drawing board and went over everything with a fine tooth comb.
I was using single point Centre AF in selectable mode (movable point). I have now switched to single point spot AF (Centre).
This may or may not be better, I can't tell at this point. The selectable point uses 1 of 33 points, just like spot mode, but in spot mode the AF point square on the viewfinder gets smaller.
I have for the time being unpacked my 645z so things are ok for now as I brought it along for the trip.
I need to do some further testing before I get back to you all. I am seeing some shot to shot inconsistencies in sharpness, but am wondering if this is to do with the sensor stabilizer. Is it effective at higher shutter speeds of say 1/1000 on a 15mm lens, or should it be turned off for that type of use? I don't know.
Thanks for the ideas! I will keep this thread going over the course of my trip and report back. I so very much want to like the K1.
Scott

Originally posted by Mikesul I hope the OP is trying some of these suggestions. The k-1 has very reliable and accurate autofocus. The only complaint some people have is that it is not as quick in its tracking (in AF-C) as some other brands. With AF-S and especially with spot it is quick and very accurate. There may be some equipment problem but more likely it is something to do with his settings. It is annoying when people complain generally about a device when they have only just started to work with the device and only have tried the one example. It is clear by now from all the reports of users that there is very little wrong with the K-1. It is unfortunate that he has to deal with this on vacation when it will probably be difficult to get help if the problem is a fault with his copy of the K-1.
I have the 645z on board so no worries if the K1 is a problem
