Hi guys, Super strong Pentax rumour! New mirrorless camera K 01, a few specs, same sensor as K5,max shutter speed 1/4000 sec. No phase detect AF (this to me proved that Pentax is incapable of making a good phase detect system) , viewfinder type not confirmed. So no optical viewfinder!! Well that's it for me! bye bye Pentax

You missed the most important bit: K-mount

So it's similar to the Sony SLT series then - minus the semi-transparent mirror. It'll be interesting so see in how far they were able to shrink it. And hopefully they've used a less aggressive AA filter.

Well, it's a rumor, so there's hope it's not true. Using an existing DSLR mount for a mirrorless camera is not a smart idea, unless we talk about a "mirrorless DSLR" like the Sonys are.

Well, from a cost-cutting perspective it makes sense and it doesn't hurt anyway assuming that their CAF works fine enough.

It never does as it can never determine the direction of the focus. It is a silly idea, to get rid of phase detect AF for no reason at all (camera's won't get smaller, lenses will still be the same distance from the sensor with K-mount).
As silly as using NEX with Alpha mount lenses only. Or micro 4/3rds with 4/3rds lenses only.

You can, of course, detect the direction of focus with C-AF. Just take two AF readings and you got both direction as well as object speed. Accuracy is just a matter of frequency with is no magic either these days. Additionally C-AF can do real shape detection whereas P-AF remains comparatively stupid.
Hi again, The strongly rumoured K 01 mirrorless camera : Contrast detect 85 points
dimensions mm: 121 wide, 79 high, 59 depth
Weight: 560 grms with battery ( 110 less than K5)
and at least there is the K mount + 40mm F 2.8
Lets wait and see Dave's clichés

That means you can't. You have to do a lens movement inbetween. The speed and predictable qualities for phase detect is that you can see it right away.
On the two readings with just contrast detect AF: you can not determine speed. Neither can you with PD-AF. (And the speed has nothing to do with determining the direction of focus anyway, only with tracking focus). Only on paper you can. But in real, you need to know too much, too accurate about the lens in use. So in real, it always is a process of more steps.
