LensRentals: underwhelmed by Metabones adapters; optimistic about Sigma MC-11

Whether the problem is noticeable by the user is irrelevant.

The user may not have noticed the issue, but others might.

Stabilisation blur caused by overcompensation is difficult to determine because it can be confused with other causes, and will more or less susceptible at different shutter speeds.

The point is, to achieve the best or sharpest image possible, only one stabilisation system should be active, not two at the same time.

But when you shoot with native FE lenses, both IS are activated.

Don't agree. There is the concept of JND ... "just noticeably different".

Lower IQ may not be visible in a 4x6" print or on the web, but be obvious with a 20x30" print, especially viewed up close.

Agree ... lots of things going on and difficult to isolate.

I've read that Sony native lenses with OSS somehow coordinate with IBIS. This may also be the case with the Batis 85 with OSS.

Note that the only Sony native FE lenses I own don't have OSS.

In the latest article from LensRentals regarding the Sigma MC-11, the Metabones adapters came in for repeated criticism:

https://www.lensrentals.com/blog/2016/06/a-look-at-the-new-sigma-mc-11-lens-adapter/
thx for the link... since there are two versions of the mc-11, just making sure that they tested the ef-mount adapter: "We’ve recently received the Sigma MC-11 Sony E to Canon EF mount adapter"

"If you are shooting with Sigma glass the answer is pretty clear that you would want to use the MC-11."

so they tested and are recommending the ef-mount adapter, not the sigma mount mc-11?

Interesting,

I can honestly say I have never had any issues with my Metabones IV adapter.

It is permanently attached to my Canon 16-35mm f4 IS, and performs so well on my a7rii, I sold my Sony FE 16-35mm f4 OSS.

I guess attaching/detaching the adapter consistently possibly causes connection errors, and loosened screws?

Hopefully I won't encounter the same problem in the future.

J
I get the impression earlier Metabones products had quality issues that have been resolved with newer units.
 
Just wanted to share a quick update about my experience with the MC-11:

Tired of testing static subjects at home, I took my slowest AF camera (A7R) and my longest lens and wanted to see how it goes trying to shoot these cute little subjects we have in the fjordbay in front of my building.

I did the same exercise last week with the same combo (and MB instead) and came back home so disappointed (nearly all were misses) that I almost bought a 5DSr instead of the A7RII.

This time it was a much pleasant experience. It took between 2-3 seconds to achieve focus (not too bad for CDAF, since it´s about the same time it takes me to MF) and the few misses I had were mostly because these birds were rejecting to pose :)

I can do better with more patience and experience (must learn to autofocus again) but so far I am happy.

Edit: just speculation here, but after posting these images and looking at the EXIF I guess the reason some Canon lenses work is because there is an equivalent Sigma lens they can override the AF settings to through the adapter.

-Works fine with my Canon 200mm, 400mm (quick AF even with my A7/A7R).
Whoa! Is that the Canon 400mm f/5.6L you're referring to? With the MC-11?

That is a very interesting combination with any A7x body. Please tell us more. Especially autofocus performance!

Yes, is that :)

It works surprisingly well, even with contrast detect only like the A7R. I shared some early experiences in my previous post.

On the A7RII is even better, you can effectively do continuous AF with the Canon 400mm F5.6 and MC-11!!!

The best and most consistent experience I have had with adapting to the A7R2 has been with the Sigma MC-11 in conjunction with Sigma Art lenses. While the adapter is great for those lenses, it is not the best for Canon lenses unless you plan on only using AF-S.

With regard to the MB IV T. The article is absolute spot on with regard to reliability. Every few power cycles, the adapter decides to take a dump and no longer AF. It still appears to maintain an electronic data connection as far as allowing you to change aperture and take shots, but AF doesn't work until reboot. This has been the case with both copies of the MB that I have had. I finally decided to keep the second one as I assumed at that point that it was just going to have to be the way I operated with the rig. This has not happened to me yet with the MC-11. But I have had the crash in AF-C. I also have not been able to use my AF converted Contax Zeiss 50/1.4 with the MC-11 where it works just fine with the MB. So there are definitely pros and cons.

While I will not recommend the MC-11 for anything other than the current line of Sigma lenses, I can say that it has been the best so far with the right lenses. The MB is glitchy no matter which lenses I use with it. But it appears to be more forgiving in general with Canon glass if you need anything other than AF-S. If I were starting from scratch, I would definitely have just dumped everything I could have that was Canon branded and just went with Sigma stuff. As it stands though, I'll be using both adapters for the foreseeable future.
 
I have tested the Sigma Mc-11 with Canon EF 24-105 f4 IS USM and can confirm that the automatic IBIS does not work at all ( greed out ). When you switch the lens IS, manual IBIS is available, so you can select the FL but then you get the double stabilisation, which causes terrible corner smearing. Also, with zooms using this adapter it is completely impractical as you have to manually change the FL every time you zoom in and out.

I've send the Sigma back, Metabones is the only adapter that allows proper stabilisation with CanonEF IS lenses.
 
The Metabones IV adapter allows you to switch between optical stabilisation and in built stabilisation (or to switch both off) via an external button on the Metabones adapter.

How does the MC-11 do this? Or doesn't it allow you these options?

J
Nope. Sigma MC-11 causes Canon lens based IS and Sony in body Steady Shot to be conflicted. You can not choose which one to be activated and get over-compensated. causing blurring image corner. The only way is to shut them off.
I don't find that to be a problem with Canon EF lenses with IS, using my FotodioX adapter. My practice is to turn off IS on the lens, and rely on IBIS.

I'd think it would be difficult to test this. What kind of lp/ph with different combinations? My speculation is that differences would be subtle, and not readily discernible by eye-ball.
Which IBIS - automatic or manual selection? If manual, this could only work with fixed FL lenses, not zooms.

IIRC, the a7Rii can detect my Canon zooms and EF 35mm prime with FotodioX adapter, and have the correct FL.

The issue is with fully manual lenses with no electrical connections, like my Samyang's. That would also apply to "legacy, film-era lenses.

Have you tried the EF24-105L IS ? How is the AF using Fotodiox? If the automatic IBIS works and the AF is acceptable, perhaps I could use this combination.

This is only a bit relevant to the topic but I've had no trouble with len's stabilisation and IBIS using my Viltrox adapter. If both of them are enabled then it would over-compensate and cause blurry picture, but I can enable either of them (i.e., leaving only the lens' OS enabled or the camera's IBIS enabled, they can be toggled independently of each other).

Edit: with the Viltrox adapter (and probably others such as MB) the camera knows about the lens' current focal length so IBIS works properly, I don't need to set the FL manually.

Hey, thanks for that info. I found the Sigma adapter completely useless with Canon IS zooms but the AF ( PDAF enabled ) was very fast and accurate. I can't believe Sigma have released this adapter without sorting out the stabilisation issue, which as someone above reported conflicts even with their own lenses.

How is Viltrox as far as AF concerned ? Which Canon lenses do you use with it?

I don't have many Canon lenses but have tested a couple of those. The lens I'm using with it most often is Canon 24-105mm f4. According to Brian Smith the Viltrox adapter's compatibility is on par with the Metabones as far as AF is concerned: http://briansmith.com/sony-a7rii-canon-ef-smart-adapter-tests/ . However in terms of IS support it seems to be a notch above (mainly because we don't need the latest MB4 adapter for the IS switching stuff).

Please note that the IBIS support has not been tested extensively elsewhere and I can only provide my anecdotal evidence. Would be nice if someone else could chime in.

The Canon-mount lenses I've tested with are: Canon 18-55, Tamron 18-200, Sigma 105 macro (film-era, AF not working), Canon 24-105, Sigma 70-200 f2.8 (film-era, AF not working), Canon 28-70 f.35-4.5 (film-era, AF not working), Tamron 70-200 f2.8. Except the ones noted, all lens AF work as expected and snappy on my A7II.

Wow! That's a shot that I could never capture with my Tamron 150-600 on my 7RM2 - incredible IQ! Nice work! Were you on a tripod? IBIS on or off? Off camera flash?

Have you had a chance to take this combination outside where there might be moving objects - like BIRDS? That's my dream BIF rig - the EF 400/5.6L on my 7RM2, but the missing piece so far has been the adapter.

It's curious that the exif on your photo calsl the lens a "DT 400mm F5.6 SAM". Do you suppose that's a translation error in the MC-11? The lens I lust after is the Canon EF 400/5.6L - the exact same lens that's shown in your Gear List, so I have no doubt were on the same page.

Yep, this is the Canon EF 400/5.6L shot handheld with A7RII and IBIS On. The MC-11 adapter somehow translates it as an equivalent Sigma lens (maybe that is why it works so well)

I posted some with my older A7R and same lens earlier in this thread. I could only do single AF but it is fully workable (not BIF, of course). Here they are again:
