国内手机基本都是直接拿sony的传感器来用，集成了相位对焦点不意外。
松下应该是死认反差对焦了。
奥巴如果全面更换成sony的传感器，新出的机型也会有相位对焦。

我的感觉是，奥巴仅仅在最高级别的EM1上实现了相位对焦
是故意的商业行为
松下是什么考虑，不知道
在 奥巴的 E-PL 或者 EM10级别实现相位对焦前，我是不会升级了

对焦是机身的事儿， 和镜头有啥关系？ 对焦的时候， 机身指挥镜头玩什么地方移动

Does the Sony FE 24-70 f/2.8 GM support ph...

Packafoma28 Sep 2016
I recently purchased an a7R II along with a Sony FE 24-70 f/2.8 GM lens (
SEL2470GM). I bought the lens on eBay. It was listed as manufacturer
refurbished and does appear to be genuine and in excellent condition.
Both the camera and lens are working great for the most part. However, I was
surprised to discover that the lens is not capable of phase detection
autofocus.
I have updated the camera firmware to ver 3.30. I cannot find any firmware
updates for the lens, which is running ver 01.
When using AF-C, the lens hunts for focus continuously with rapid, jittery
movements. It takes a long time to get a lock even if the aperture is wide
open and the subject is brightly lit and not moving. Meanwhile, AF-S works
beautifully.
In the settings, Phase Detect. Area and AF System are grayed out along with
a message that says “Invalid with this lens.”
Along with plenty of Googling, I have scoured Sony's website and B&H for
some mention of phase detection in their descriptions of this or any Sony
FE lens. It does not seem to be a spec that they ever list. Yet, I believe
at least some lenses are compatible with PD. I found one post on this site
that indicated that the Sony FE 50mm f/1.8 (SEL50F18F) works with PD. And I
saw a post about a lower-end zoom that supposedly works.
So I have a few questions:
As in the title: Does the Sony FE 24-70 f/2.8 GM support phase detection AF
on the a7R II? I would be surprised that a native lens from their premium GM
line would not, and some posts have indicated that all Sony native lenses
should be PD capable. I know that A-mount lenses can even use PD with an
adaptor.
If some Sony native E-mount lenses are not compatible with phase detection,
which ones are? I can't find a list anywhere, and like I said, there is
never any mention of it in the specs.
If you have a FE 24-70 f/2.8 GM, what firmware version does it have?
Thanks!

I guess no one who is active in the Sony Alpha Forum owns a Sony FE 24-70 f/
2.8 GM lens. My question really pertains to all Sony E-Mount lenses
though.
Here is the end of a chat I had with a Sony support tech. The news was
disappointing. I still find it hard to believe that Sony’s native lenses
lack a hybrid focus capability that works with A-Mount and even Canon EF.
I’m coming from Canon and Panasonic cameras. So if I’m missing something,
please let me know!

A lack of response is due to a non-seqyitor being considerably
difficult to address. Only difficult, or tricky, but not impossible
..... so, OK, I'll bite:
Lenses do not support or fail to support CD or PD versions of AF.
Lenses take orders from the camera body. The body tells the AF
motor to go ahead or go back, how fast etc etc. How the camera
body "decides" which commands to issue to the lens is none of
the lens's bidnez. Lens get commands, lens obeys. Body makes
"decisions" based on whatever detection systems that particular
model of body has onboard. It doesn't negotiate with the lens or
conference with it. It just tells the lens "Do this, right NOW".
IOW, had you asked whether a certain tripod supported CD AF
you'd find no one has much of an answer to that, or whether that
tripod supports "i-TTL-HS- wireless fill-in flash" .... same problem
.
That dog won't hunt.
And acoarst the Sony documentation, and marketing material,
doesn't mention anything neither ... cuz no one is ever spozed to
ask any non-sequitors :-)
"When using AF-C, the lens hunts for focus continuously

Meanwhile, AF-S works beautifully."
That is all well and good. Of course AF-C "takes a long time to
get a lock" while AF-S "works beautifully". A "long time"
; ? How
about more like "never" ? "C" means continuous. "
Continuous"
isn't continuous if it locks on, right ? So acoarst "S"
; does lock
on, cuz "S" means "single" ... one single final
decision about
what to focus on, and then stay put [lock on].
If you correctly quoted the error message, then I would hafta
call that message poorly worded. “Invalid with this lens.” ?
160;
I do see how someone may then think the lens is an issue here.
Please double check all choices that lead up to that message,
cuz it just makes no sense at all.
