Achim--thanks so much for sharing your findings. Landscape photography is my passion and I have been very seriously looking at the A7R/TS-E combination. I apologize if you've written this elsewhere, but what L bracket are you using? Looks like a Hejnar spacer? Does this bracket/spacer combo feel solid?
I've become used to using the depth of field preview on my 5DII. Does the Metabones III give some kind of depth of field preview functionality? Really looking forward to all those using the A7R with Canon TS-E lenses reporting on their field experience. Thanks in advance to all those who are putting this system through its paces and taking the time to share it with all of us. This work is invaluable to this community.

1 x spacer for Metabones EF to E (Canon to Sony NEX) adapter GEN 2 (Metabones 2)
1 x L bracket base 2 (L base 2)
1 x L bracket side 3 (L side 3)
The L-bracket is very solid. I don't see any difference to RRS brackets in terms of quality though the bracket is from 2 single pieces. Screw connection is very tight and doesn't move at all.
I bought the spacer since i have read from others that TS-E Lenses might be limited in shift down without the spacer.
In fact that is not the case with the Hejnar bracket. You can even shift full way down without the spacer.
When i bought the spacer there was only the one for the Metabones 2 adapter available. It's a little bit too wide for the Mark III adapter. You can even see in my image that there is half of a millimeter space between the foot of the adapter and the side of the spacer. However once it's screwed tight it doesn't move at all.
I am fine with that setup.

The Metabones Mark III has two operating modes:
1) Standard mode: Aperture is wide open all the time. By pressing the button at the side of the adapter you can stop down to the aperture that is set on the Sony (similar as DOF preview button)
2) Advanced mode:
For getting there you need to have your camera turned on and the lens connected! Take the camera off the adapter mount (turning it some degrees is enough. The connectors of the camera just needs to lose connection to the adapter). Then press down the button at the side of the adapter and while pressing the button connect the Camera.
In that advanced mode your lens will be always in working aperture. A must when you work with TS-E lenses.
Drawback is that the adapter switches back to standard mode when you change the battery of the camera or connect another lens. Then you always need to set it again into advanced mode as i described it. But one can live with that.

No, you can force it in advanced mode. I set it once, and never touch it anymore even removing batteries and changing lenses. re read metabones instructions (can't remeber). I think you have to keep buttons pushed and turn camera off to lock advanced mode.

Hey there,
because of the findings and posting from Marc Aurel and Fred i also did some research on the flare issue that i want to share with you.
I own both the 24mm and 17mm PC-E lenses, the Sony A7R and the Metabones Mark III adapter.
First thing i did was to coat the inner surface of my adapter with Tetenal Camera varnish, black and deep mat.
This doesn't help at all to get rid of the flares. Save your bucks and don't even try it.
Next try was that i bought self adhesive Black Flock Paper. http://www.edmundoptics.com/lab-production/general-tools/light-absorbing-black-out-material/1502?#products
F***ing expensive but the quality seems to be good. I didn't want to take the risk to get much sensor dirt from cheap paper that loses it's fibers.
In the first step i laminated only the front facing part of the adapter with the black flock paper but not the inside like here:
Many many thanks to Marc Aurel who shared his experience and all others who contributed.
That was really a great help to solve the issues!
By the way:
The fully laminated adapter still allows to shift full way 12mm. At least with the black flock paper that i used.
There is a very very slight amount of vignetting but still much less than you always have on the side of the image circle of the lens at full shift. But for sure there is no black cut off in the frame.
Cheers
Achim

Great post, very instructive. I've cancelled my order for the Tetenal Kameralack.
I went on the edmundoptics website, saw the price for 2 adhesive sheets (18.95€), thought.. "OK, if need be, I'll suck up the cost", then saw the shipping at 30.80€... wow.
Would you be willing to sell me some of your paper? I live in France. I'm ready to pay an extra for the painful process
If not, thank you anyway for your tests! Very helpful.
I've tried to keep button pushed while turning the camera off but it doesn't work.
When i replace the battery i am always back in "green mode".
Would you be so kind and tell me how to lock it?
I don't have a manual for my adapter....
Thank you!
Achim
From memory : press the button and keep it pressed, put the adapter, turn camera on, turn camera off. Only now you can release the button
The process was write on a small paper I had with the adapter. It may still be in the box at home, so I will check back this evening.

If someone want it, I can give it. But it is compiled for windows x64. I can give the py file but you will need a python environment with pyqt.
There is some plugins that does that in lightroom with exiftool installed, but they change one lens at a time, write in raw files, and store their presets in lightroom preferences file itself !! My tool does nothing, nowhere, apart changing lens line in xmp file.
If interested, let me know and I will post all needed on my blog.

Many thanks to Marc Aurel.
Marc's solution is really effective for flare, not only with TS-E lenses but also with the widest side of 16-35LII, which otherwise flares easily with the Metabone's.
Some shots from our New Year's holiday in the south of Japan, taken with A7r + 16-35LII.

I'm not trying to be too negative, but isn't the issue of flare with the Metabones really a product defect that is being corrected by buyers? It seems Metabones should be on top of such internal reflections generating flare. Could the adapter be redesigned to eliminate the need for flocking paper, or could the manufacture add anti-reflectance solution?
It just seems Metabones is putting owners through a lot of unnecessary bother and expense with internal flare and the external mount clearance issues.
Obviously, these issues haven't deterred enthusiastic adopters!

Totally agree with you. Now what ? Actually, Metabones seems the best adapter for us. Tweak it with anti reflective, and it is really great. But, you are right, and I guess that A7R have put lot more demand and feedback on these adapters, so I wouldn't be surprised to see new such adapters and Metabones updates on them. It's just what is the best tool now, is it usefull for you ? Sure, Metabones one isn't cheap, and need extra work, but is there any better solution ? Any 36mp high DR sensor from Canon ? No ...

Adding flocking paper is not really a big deal but dealing with misalignment is a different story, and more a pain in the ... where the sun doesn't shine . There is even a copy-to-copy variation within the same brand of adapter although Metabones seems to offer the best fit. At least, at this point until that German-made adapter becomes available in a few months.

Fully agree with you, Gunzorro!
I contacted Metabones support yesterday to make them aware of this thread and my findings.
Pointed out that there is a serious issue and their adapter leads to low image quality due to internal reflections.
I've asked if they are aware and what they will do to solve the problem.
Here's their answer: (Full Email. I didn't skip any line...)
HI,A,
We improved this issue on EF mark III adapter now….
No need a black paper now.
Thank you!

What can one of us do with that answer?
I'm a little bit pissed off on this answer that doesn't tell and help me anything.

Have tried that and a few other options with turning on/off and pressed button but it still doesn't work.
After replacing the battery my adapter switches back to green mode.

Achim -- That Metabones response is a little concerning. It seems to indicate they feel they have solved the problem, case closed. Trouble ticket closed!
I would have thought at the very first rumored report of reflections/obstructions/flaring their QA would check with camera and simple visual observation to clear up the matter.
Am I the only one that feels the inside barrel/baffles is a little small? And why the slanted surfaces? -- that's like installing a slide for lightening. Seem sort of a Frankenstein carry-over in design. Isn't it basically an extension tube with a little electronics?
I'm not an engineer, but it seems if Canon can make their tele-extenders as a clean package, this should be a slam-dunk. Electronically coupled extension tube with rotating collar and foot? No elements, or anything! Whoosh! Three points!

Thank you so much!
However it definitely doesn't work on my Mark III adapter.
As soon as i take the battery out, replace it and switch the camera on again, the adapter is back in green mode.
I really wonder that it works on yours.
Maybe yours is running a different firmware?

I'm not a physicist in optics either but i agree with you.
Looks a little bit over engineered and a much more simple and straight forward design might cause less issues.
Maybe it helped them to justify the price tag..
