Pentax using traditional, stoneage SAFOX VIII AF module about 6 years
thats going on the assumption that older=worse. they have been using the K mount for nearly 37 years, does that make it bad? pert of the reason for the slower performance is the 'double check' system pentax employs in its AF. something most people don't know or ignore. I am so tired of seeing 'SAFOX is bad because its old.' I have no doubts that pentax could improve the SAFOX system to easily compete with canon and nikon. you want a whole new system that could be glitchy and have problems? it will cost you more money and delay a release. or they can improve the system that works. but hey I guess some people just want something new and are not concerned with quality and reliability.
