By Lens Rentals: Part 1, Part 2 and Part 3.
Via Post @DPR Pentax Forum.
Quick Conclusions:-
1. Live View CDAF is more accurate than conventional SLR PMAF for still objects;
2. New body is improved over old one for better PMAF accuracy with *any* lenses - the 5D3 was tested against the 5D2 head-to-head, with the same set of lenses, old and new;
3. New lenses are improved over old models for better PMAF accuracy with *any* bodies, old or new!
4. So, with the latest combinations of the newest bodies and lenses, PMAF's accuracy could actually match that of the LV CDAF, but consistency is still not as good.
But after all, don't yet forget about the true values of the PMAF, i.e., better low light performance, better continuous focus tracking and higher speed (which is faster in general).
