I thought you said AF-S doesn't?
I bet it does but that doesn't mean PD is needed for that. Computer vision has still loads of potential when cameras ship with more powerful compute power.

If AF-S does support pdaf, what's the diff btween AF-S and AF-A? If u set to AF-S, camera hunt all the time. Try it on your camera. You won't see this hunting in AF-A mode that many. So as of now, I believe what Sony told me, AF-S is CDAF, AF-A is hybrid AF and AF-C is pdaf.
Hmm that's why I am considering this...

more slick and additional storage for the hot shoe cover on the strap at slightly over 2 times the price of a stock Sony hot shoe cover.
I just need to confirm if A6000 hot shoe slot is universal as other brand DSLR hot shoe

It's an ISO mount hotshot so i belive most covers will fit.
However, because it has the bulti interfact port inside...normal covers will NOT cover the hotshoe all the way like the sony ones which is slightly longer. I believe many have used generic covers...i myself just leave the hotshoe exposed...becuase i know i will lose any cover in no time whenever i mount a flash and forget where i keep the cap
I thought AF-A is just a mode that helps you auto select between AF-S and AF-C depending on scenario. From what I read, this is apparently not fixed even when you have focus lock, so you can lock focus of a person with AF-S and when the person is moving, it automatically switches to AF-C to track. I don't feel the camera hunts a lot with AF-S actually. Not anymore than my DSLR.
I think what ageha could mean is that AF-S still uses a combination of CDAF and PDAF to get the AF lock, except it halts on focus confirmation.
However, since it doesn't actively track like what AF-C does, then it's not so obvious that PDAF is in use. I believe what PDAF has given AF-C in this camera, is the ability to predict moving targets, whereas it previously required to try to track fast enough on every shot with its limited sensors (though the multiple PDAF sensors also helps in this aspect). This prediction is probably why I perceive AF-C hunts quite a bit if it's on an erratically moving subject rather than something moving straight like a car, etc. Can try just pointing to a still object in AF-C and then swaying your body back and forth a bit and see what happens.. basically every mode has its function and works better in certain scenarios.
I do think it's a logical reason that the CDAF+PDAF hybrid is the reason why the a6000 AF seems to be more accurate than the Nex 7 in AF-S mode. Don't forget pure CDAF tends to focus on areas with higher contrast even if it's in the background, so just try shooting those type of shots to test. If it picks the lesser contrast foreground more accurately, in theory the camera should be using some of the PDAF to help pick the correct spot.
Just my amateur view based on my limited understanding.. I think that the PDAF in the a6000 is quite different from that on a DSLR so probably need to read up more to understand how it really works.

I agree this this point
The test you suggest is not a test of AF on a moving object. If you move your body/camera in relative to the scene, you will have the whole image on the sensor moving in tendem, so it will confuse the focusing system. It is different from a real moving subject moving across the frame with the background relatively still. Just saying.
I thought about it, another reason could be that the Bionz X chip is a couple more times faster than the last generation, thus the data processing for the CDAF is much much faster such that the hunting effect is shortened and not as noticeable?

That's the exact beauty of this hot shoe cover.....it allows you to store your hot shoe cover in a location you know where you keep it when you mount your flash.

Yes! You guys make sense! The more I read the more I think pdaf is present in AF-S!

According to what I gathered from another forum:
AF-S....uses PDAF to close in on the focus point and finishes off with CDAF for the ultimate accuracy. Thereby a touch slower than AF-C
AF-C....uses purely PDAF for the speed, but sacrifice ultimate accuracy without the CDAF

Yes, you are right. Will shoot more with various mode to have a feel.
thought about ordering it online...but just remembered I am going to be using the Peak Design Leash.....so not compatible with the strap storage...so decided against it :dunno:

Interesting observation last night while recording videos inside a room with while fluorescent lighting.
A6000 + SEL35F18.
While I was recording a video under Aperture mode with F1.8, I can see a yellow horizontal strip moving down slowly on the LCD. At first I thought there is something wrong with the lens or the camera so I stopped recording immediately. Upon playback, I can clearly see the yellow strip on the recorded video.
Power off then on again. Same settings record another video and same thing happened. Then I just play around with the ISO, EV and aperture settings and to my surprise, the yellow strip started to diminish as I increase the F size from 1.8 to 2.2 and so on. The yellow strip finally disappeared at F3.5.
Anyone had this problem before?

Tonight i go home try let u know.
All these technical discussion of this new camera fascinate me.
Read something interesting this morning.

Sunny weather today.
Good time for some picture making.

Something to do with the bandwith of the fluorescent lighting, you'll get something similar if you try recording the TV or Computer monitor.
Just updated 2 of my lenses from Ver.01 to Ver.02: SEL1855 and the SEL50F18
Did abit of testing prior to update to get a feel of the difference in the upgraded Hybrid function.
A6000 with SEL1855/SEL50F18 (ver.01),
- the AF-A is not selectable.
- AF-S is slow and hunts alot.
- With my hand on the lens body during AF attempts, can feel that the AF motor is very busy and rumbles quite alot.
- no dancing tiny green squares (as expected)
- AF-C, though selectable, is purely CDAF and is sloooowwwww
A6000 with SEL/SEL50F18 (ver.02),
- AF-A is can be selected now
- AF-S is much faster and the only time I notice any hunting (minute amount) is during difficult focusing situation such as area of low contrast or light
- With my hands on the lens body during AF attempts, can feel that AF motor is much less taxed.
- Dancing tiny green squares!
- AFC, amazingly fast!
My SEL18200LE is already Ver.02 out of the box. So performs as expected on the A6000 body.
The SEL1670Z is also hybrid AF ready out of the factory. I feel it is that tiny bit faster in AF than the rest of the older lenses...though that might have been psychological LOL
Have not have chance to try out my SEL35F18 or the SEL16F28 + UWA yet...both do not seem to need update based on the update page.

Have anyone tried the metabones on A6000 with EF lens? ... any advice to recommend?
1) Will the AF performance be similar (unlikely) and if not how much does it affect especially in AF-C
2) Any other performance degradation using this combi?
3) Was considering either eventually getting SEL35f18 or using metabones to match with my current EF lenses
