I don't know. I hope so - because Hoya has gotten A LOT of Patents issued in the last couple years related to cameras...considering how long it takes to get a patent issued, wouldn't be hard to think these were related to Pentax. One is for butch looking AF module with and array using 5x9 line sensors with partial areas.
Quote: by "faster AF" does it mean how fast and accurate the AF system takes to focus on the right subject? Because I just thought, if a "faster" AF system actually drives the screw mechanism faster than older AF software can...
Focusing on the right subject seems, to me, to be the biggest issue. For most, I think that would mean having more precise control over what they want the AF to focus on, which would mean smaller AF sensors. AF-C is an issue also, so it seems more AF sensors would be needed and better tracking algorithms. I don't feel the current sensors aren't sensitive enough - they seem to be able to lock in on just the slightest contrast, and reportedly in the EV ranges they are supposed to.
Anyway, gotta figure more sensors and more brains need yet more processing power (speed) to resolve all the intergral operations for all the sensor areas.
Once the (correct) defocus amount is figured, then it IS a matter of motor speed and control and precision. New AF/SDM/DC motors could help, tighter servo loops, less build slop, etc. See a few patents for that type of stuff too, so who knows!
