Originally posted by opiedog true that AF has improved since the *istD, but this is the first time that a new SAFOX has been used.
there's also indication that the hardware (SAFOX IX) has better optics for more precise AF.
i also found it unusual for Pentax to describe the algorithm changes as drastic. maybe just a translation from japanese to english.
also the first time Pentax has announced shutter or focus priority modes for AFC.
i'm hoping the AF accuracy and speed changes and tracking (predictive?) are drastically better!
True, the *istD already used SAFOX VIII. Note though that for the K-7 Pentax did add a + to the designation, i.e. the K-7 using SAFOX VIII+. Perhaps they just realised that keeping the SAFOX VIII designation wasn't exactly the best way to communicate that the system was being continuously upgraded?
Anyway, I'm helping you hope SAFOX IX will be a great leap ahead. But I'm remaining cautiously realistic as well...
