Originally posted by reh321 My KP seems to focus relatively slowly in LV, so I'm guessing it doesn't have on-sensor PDAF.
On page three of the features section on the product page, it says so.
“The PENTAX K-70 features PENTAX’s first Hybrid AF system during Live View autofocus operation. By coupling a contrast-detection AF sensor with superior focusing accuracy with an image-plane phase-matching AF sensor positioned on the image sensor’s surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint autofocusing on the subject.”

It probably still isn’t that fast, because most lenses weren’t designed for it, but it is in the camera.
