Any news about Pentax AF system breakthrough?

As we know the most photo companies implement different new technologies in AF system.
Canon - Dual Pixel AF system + very advanced phase AF
Nikon has simply the best phase AF system
Sony, Fuji and Olympus - Hybrid AF system - rather advanced already
Panasonic - Depth from Defocus AF system

Ricoh - archaistic phase and contrast AF - nothing new at all.
Hybrid AF in K-70 is used only for video with several lenses and no any serious explanation of this system in marketing information.


When will we see something new? How do you think - could we see new AF system this year?

There was information about possibility of using SR system for better focusing, but...

Ricoh will do their own thing in their own time - but we know they are trying

For a while, Pentax was leading in low light sensitivity. So it's not like they're doing nothing

On paper - yes. For several months. My K-5IIs has EV-3, but it doesn't help in real life.

But it can't cancel the fact that we don't see any serious steps from Ricoh in this direction.
To put sensor with higher sensitivity is not new technology.

I'm not a technical person but, I think improvements on the lens motors would help a lot. Like the new 55-300 with PLM technology. Just my thought, Pentax should upgrade their lens line up.

Sour grapes. In real life, I noticed significant AF improvements, from the K-5IIs to the K-1 - and with my new lenses. And I will continue to notice significant AF improvements, because I can afford it. I don't have to pretend it doesn't happen.

Pentax is not a very communicative company. I'm sure a different marketing department would phrase that "algorithm improvement " rather differently...

I am sure Pentax could match Nikon's (or anyone else's) AF if they wanted to. It's fundamentally a matter of engineering, resources and priorities, not magic.

Mentioning other brands is more a manifest of envy, rather than a need.

You use a K5IIs. So, in order to get a significant improvement of AF performance without switching to Nikon, Pentax does not need to raise a finger for you, you only need to buy a K3 :-). And show us all of your nice AF tracking shots.

There is something new in this old technology.
Check D5 and D500's AF system. It's extensive way in some aspects, but very effective.

Ricoh has no even something close.

I mean, if Pentax AF is dinosaur, having a camera that's two generation behind the lastly released Pentax gear, place you back in pre-dinausorus era.

Well, I could've jumped to Nikon instead going K-1, so it's not me. It's not you either. Who is it, then?
