I checked Pentax Canada website about focusing system

Pentax Canada - K-x

they marked
Focusing System
Type TTL phase-difference 11 point (9 cross) wide autofocus system (SAFOX VIII+)

since a lot of websites said the focusing system is SAFOX III not III+

which one is correct ?

You think other sites know better than Pentax?

There's really no significant different between VIII+ and VIII - just an extra sensor for fine tuning focus under tungsten or similarly-colored light. There's actually more difference between various different VIII cameras than that - number, type, and position of focus points, selectability, support for SDM, algorithms used, etc.
