Although I was about to make the jump to the K-3 II, realistically, I don't need anything better than the K-5 that I already have, except for the fact its AF behaviour, particularly under some artificial lights, has been inconsistent from the beginning.
I believe it has been adequately established that the K-3 AF is far superior to that of the K-5. The K-3 Review
Pentax K-3 Review - Autofocus | PentaxForums.com Reviews gives the impression that PDAF differences between the K-3 and the K-5 II are not significant. Also, AF comparisons tend to discuss speed more than precision.
I don't often use Liveview, and I normally use only centre point AF. I am not particularly concerned with AF tracking, or even extreme AF speed (though hunting is a nuisance). I am after AF precision (i.e. accuracy and consistency), at reasonable speed.
So, although I'd like something with more consistent AF than my K-5, I'm also keen to not spend more money than I must. Which leads to the question: is the PDAF on the K-5 II good enough so that there is no need for me to spend more money on something I don't need?
I'd like to hear from people who have owned both the K-5 II and K-3 and get their views on the relative PDAF performance of these two cameras in actual use.
All other recent models are excluded from consideration due to absence of the top LCD.
Thanks.
