But who knows, these sources may all be garbage.
I dunno. I've read the subsequent DPAF patents, and there isn't anything remotely revolutionary in there. Mostly just using different sized photodiodes for the AF part, and a means of increasing sensitivity for AF without reducing IQ. If that's all Canon's got for the 7D II, they are going to take a HUGE reputation hit...and they HAVE to know that... (If they don't, then they've totally lost touch with their customer base, and I am seriously hoping that's not the case.)
Sounded like they were hinting at way upping the speed and making it not focus hunt at all and perform super well for real time tracking and focusing during video.
But who knows.
That still doesn't sound revolutionary or anything like that. It's just expected evolutions on the existing DPAF. I think the patent that covers increasing sensitivity could cover a lot of that, as all PDAF is is a bunch of highly sensitive strips of pixels that can be used to detect a phase offset. Current dedicated PDAF sensors use pixels in the strips that are huge compared to current image sensor pixels...increasing the sensitivity of the photodiodes would allow DPAF to perform at a more competitive level, and by consequence become more useful for realtime focus and focus tracking during video.
Still...it just, if that's ALL Canon does with the 7D II sensor...wow. FLOP. I think Canon is smarter than that...
