Somebody has to try out this adapter on the original a7. I'm holding out a small hope that the adapter will allow the use of native focusing (PDAF). I would like to pick up a few of the art primes.

CORRECTED - The original A7R didn't have any phase detection (PDAF) hardware - it's not possible to add it later.

The A7 has PDAF, but it seems extremely unlikely to me that Sony would expend any effort to extend the capability of that old* camera. And for the Sigma adapter to utilize such capabilities the camera would likely need the firmware changes which enabled PDAF on the Sony adapter, which was released for the A7ii and A7Rii.


*'old' being a highly flexible term in these days of quarterly product revisions.

The original A7r doesn't have PDAF, but the original A7 does have PDAF.

The A7 and the A6000 both have PDAF, but support PDAF for native E mount lenses only. In addition Sigma lists the A6000 as well as the A7 as cameras that will work with their new MC-11 mount adapter. If Sigma has pulled off PDAF even with the A6000 and original A7, then that just makes Sigma's achievement even more amazing.

Your statement is correct for A7R and A7S(II) only. Not the original A7. A7 on paper has the exact same PDAF unit as A7 II which has 117 PDAF and 25 Contrast detection points on sensor. If there is a reason SONY can't implement phase detection for A7 it is not obvious from looking at the spec and SONY has never explained to the customers the reason (other than commercially, obviously)

See this table for reference:

Thanks for the correction! I mistakenly grouped the two old models together.

Posted by Brian Smith today:

"When tested with pre-release firmware and supported lenses the MC-11 adapter offers fast and accurate PDAF and provided full AF functions for stills including focus tracking and Eye-AF. It also enables video AF with Sony mirrorless cameras that offer PDAF – including Sony a7, a7II, a7RII, a6000 & a6300."

Very promising clues for A7/A6000 achieve fast PDAF via adapter.

The sigma adapter is converting sigma global vision lenses to act as native Sony e mount lenses. It has nothing at all to do with the tech Sony added to the latest gen cameras to support adapted dslr lenses.

Regarding PDAF-support for Sony A7/A6000, I e-mailed Sigma some weeks back specifically asking about these two cameras and they told me the following:

"Yes, the MC-11 will allow full use of all the capabilities of the cameras including Phase Detection Autofocus. The MC-11 has Firmware specifically designed for each Sigma “Global Vision” lens and the Sony E mount cameras."

So, excellent news for those that have been longing for some real tele-lenses for E-mount!

Didn't you subsequently cancel the MC-11 order? If so, I assume that you returned both lenses. Where did the 35mm Art fall short of expectations?

Yes I did . The Sigma 35 Art was the best of them. Very sharp on center and corners starts getting good at 5.6. Nothing wron with lens except bokeh was good not great . I may actually buy it back after the adapter is out. I sold everything Sigma to grab the Sony 24-70 GM. I was going to wait this purchase out but was still in my Sigma glass return period so I decided to return the 24-35 cancel the adapter as I paid for it full. Had to sell the 35 1.4 Art though. Good news is it only cost me 35 dollars in the process. So it was best to do it now than wait. I'll have to see how this Sony zoom really is though. I will have all my tests to compare this week. So that should prove interesting to members and myself. I figure I can always go back to Sigma if this does not work out. But the 35 Art I really have nothing bad to say about it, if anything a little clinical, bokeh is good, bokeh balls fair, did not notice onion rings so that's a plus.

I noticed today on B&H that the kit's will be available here in the U.S. and do represent a savings of about $150 (in the case of the Art 35/1.4 + MC-11). That kit is listed as $999.00.

Well, it looks like I'm getting the MC-11 directly from Sigma, trouble is, I'm on a plane tomorrow to New Zealand leading two workshops there until May 1. They're gonna Fedex it to me in NZ on April 15. In hopes of actually receiving it, I bought the Sigma 150-600 and will bring that along and test it out on my a7rII and a6300. Will report!

Oh, side note: the 150-600 (Contemporary) is super light! It's a cinch to hand-hold. That's why I bought this one first. I have seen reviews favoring both the Contemporary and the more expensive and heavier big brother, the Sport version for sharpness. We'll see what real life shooting brings out. If it's not sharp enough, *and* the MC-11 does what we all hope it does, then I'll return the Contemporary version and get the Sport version.

I'm rather hopeful that this will solve the long telephoto that I need for wildlife!

I will be testing the MC-11 with the 150-600 on Wednesday when I get the adapter.

Does anyone know how much the MC-11 weighs?

Looking forward to this test as that's the combo that I'm really interested to use with A7rII (and maybe A6300).

Fred, the MC-11 weighs about 120 gram.
