2) It works fine as far as I can tell with my ts17 and ts24 which is the main reason I bought it to match with. I was worried that the edge fixes sony had implemented to fix extreme light angles might help rangerfinder lens but hurt regular lens. I could not find any distortion from this affect. So it passed the most important challenge for me. Including shifting to extremes and merging.
Good to hear, I was concerned that the steeply angled sensor microlenses designed for the short registration distance of the mirrorless lenses would increase the vignetting of edge/corner pixels with WA EF (longer registration) lenses. However, this impact may be less than 1/2 stop and may need quite even textures, like sky, to be seen.
6) It features feel like the Russion version of the 5diii. It all works but not smoothly
- it seems to have more vibration on shutter release than the 5diii on mirror lockup. ...Show more →
Known limitation for the Sony A7R is that there is no electronic first curtain when shooting with Live View, as there is in current Canon dSLRs. The extra vibration without electronic first curtain is more likely to impact longer focal length lenses.

Any easy way to use an external screen?
There are several good HD resolution external monitors now available from Small HD, Ikan, Marshall and others. For Manual Focus application I very strongly suggest you get an HD levels resolution screen (1280X800) that has flexible software and uses the camera HDMI output. The USB camera output is very limited to 640x480 which is fine for composition but limited for MF application.
I describe the issues in some detail here https://www.fredmiranda.com/smallhd/

Hi Scott,
Thanks for your update. Points 2 and 3 are welcome news. Does point 7 about LiveView focus suggest that it's not as good as the 5DIII (and probably 6D)? Like you, I plan to use it (A7R) mostly with TS-E, ZE, and Alt lenses, and so good LiveView manual focus is much desired.

I have experimented with this again this evening and my conclusion is that th a7r is as good to focus in live view as canon 5diii. I was confused because the sony does a 7x and 14x magnification vs 5x and 10x for sony. Of course 10x is easier to focus than 14x because 10x is more foregiving. But if you have a very good lens on a solid tripod the 14x would be better to focus. My experience in the wild is that 5x is the appropriate amount for most lens - their sharpness does not allow more focusing (eg 24-105) but the zeiss 25/2 is better and sometimes i go to 10x.
So in summary, they are different. Likely 10x is better than 14x, but it is just a different set up.

Thanks for checking Scott. Could you double check to see if the tripod mount in parallel to the camera base? I'm in contact with Metabones about this and we want to find out if more users are having this issue.

I checked and to the ability I have with a ruler and eye, the foot bottom is level with the bottom of the camera. However the little rotation we talked about makes it unlevel a bit if you rotate.

Hi Scott, you might check out 'Acratech's' L bracket, it uses two quick release plates to manage portrait/landscape orientations...see link below.
Thanks - I have the spacer foot from Hejnar photo now and the good news is it creates more room for shifting and to get the bod off without removing from L bracket. The bad news is that the spacer connects in the centre so you need two screws to attach to L plate. It will be solid but I don't have them yet. But the spacer helps.
I think you have the right idea with the clamp though. If you clamp it in you can unclamp it and use the camera off tripod quickly without a big bracket. I will go clamp shopping.

Hi Scott I ordered a RRS BPnS-S narrow plate and attached it to the foot of the Metabones adapter, the RRS plate is very similar to the Hejnar in that it lengthens the overall dimensions of the metabones foot and therefore allows the ability to fully shift and also mount the 85L, the RRS plate is dovetailed so you would be able to clamp it, it also has an anti rotational lip which prevents it from twisting.
My thought is to attach a RRS mini clamp B2-FAB-F to the L bracket and this combo would allow me to remove L bracket from the camera when I want to shoot hand held.

When using Canon lenses, especially tele lenses, does it auto focus as quickly as the Canon 5D MkIII?
In other words, would it be a good camera for sports and wildlife with Canon telephoto lenses?

As said above posts, adapter+A7(R) combo af is slow w/ Canon EF lenses, not for action shots. It is more for non-moving subjects or for mf use w/ aperture ctrl & IS. There are a few shooting bif w/ nex & Canon fd lenses w/ manual focus & peaking, so you have to rely on more mf techniques.

A7R + adapter does not support continuous AF with any Canon lens. Which is what sport, wildlife & bird shooters use.

The only camera currently on the market that focuses as fast (and as accurately) as the 5D Mark III is the 1Dx...

I tested focus speed with ef lens and adapter and the a7r with metabones adapter is
- slower than the eosm that everybody thinks is slow - 3s A7r vs 2s EOSM with 24-70v1. Similar gap with 70-200 2.8.
- slower than the 5diii (<1/2s)
In addition to Lars comment about lacking continuous focusing, unless the wildlife is dead or asleep, or you manually focus (bird perched in nest with low wind on tree) - the A7r is not going to be suitable for wildlife because it is slow.

10) 3 AEB sort of makes a galloping noise and you have to hold it down to the end for it to complete its cycle. The 5diii was more intuitive with a red light on during exposure and 1 noise per shutter.
It's a live view camera, so unless you use the electronic first curtain (only available on the A7, not the A7r), you'll have two shutter movements for each exposure -- the shutter opens between exposures so that you get the live view feed in EVF and/or LCD.
