steve, as i said (i did mean it), i agree, yours are very good points. however, i must admit i have too little experience with af-c (i'm just too old fashioned i guess), so my first question is: does the k10d or k20d appear to be doing any "guess work" while in af-c, so called predictive af, or is it just doing repeated af-s, at very high frequency? it was my impression that it does the later
, or that, if it does some guessing, well... it's not very smart guessing. so my impression is that it is using brute force for af-c, instead of trying to do it the smart way, and if that is true, the improvement with the current "force" available with the current af system if trying to do it smarter (more economical) would be rather big. that was my point.
it is not arguable if the blackout, processor overhead (when using the same processor as for image processing/i/o to the storage) are very important for high-end af-c tracking, but are we even at that point?
i don't mean to bash the pentax af (i think it's had enough), i am jsut trying to constructively figure out what might be done to improve it, for what it's worth (to be honest, as far as i am concerned, the pentax af does great: it does a hell of a better job than i can, and faster, when i let it do it -- not very often -- so i guess i can't complain, i am one of those guys who got af when switching to digital as part of the deal, and said "oh well, i'm depending on batteryes now anyway, so what the hell.." )
