BTW, is there a reason metabones couldn't eventually implement eyeAF? I guess they would need communication information from sony. Perhaps the AF performance with an adapter is still too slow.
Another BTW, it would be great if the adapter had some more weather sealing on it - like the ruber gasket at the end. I know the a7rII isn't very weather sealed, but I'm sure that gasket like the canon lenses has wouldn't hurt.

OK so here's the question. Let's say I was shooting portraits - non action - with a Canon 85 1.2 II and a 24-70 f2.8 in light equivalent to 1/30 @ ISO3200. Can I expect the AF to work well? Mostly points near the center. Accurately is more important than speed....
I'm debating if I need a Canon 5ds for this type of thing or the A7rII would do the trick.
With the A7rII and MB vs 44/45, the 85L II works extremely well. Having the IBIS to steady the shot in low light and the AF is very accurate, and quite fast. The 85L II has never been really fast, but most important is the accuracy which I never had with the 5DII. I do a lot of very low light portraits and the center AF points with the A7rII is accurate to where you wish to focus on even at f/1.2
I've just update my techart EOS-NEX III to the latest Ver 1.2.0 20151020 (bluetooth via android app on my phone).
But when I go to version parameters on my A7RII just with adapter (no lens on), The lens version (adapter so) is allways 0.2 like when the adapters was in Ver 1.1.0 20150911.
Do you know how to check the real version in adapter ?
I just did my first field test of my new Sony A7r II.
The lenses I had with me were canon 24-70 f2.8 II, tamron 15-30 f/2.8, sigma 24-35 f2 and Sony 55 f1.8.
All the lenses were fine apart from canon 24-70, especially between 35-70mm. I noticed that many photos, in which focus was quite more tricky than in others (but nothing too much, just low contrast in daylight), were slightly front focused. This was the case in >35mm and caused an acceptable sharpness in the center (not crispy though) but unacceptable sharpness in the borders (probably the front focus made the field curvature effect more noticeable). I took the same photos with manual focus and they were perfect in the center and borders even wide open. Also in photos of high contrast everything was also perfect.
As I said I didn't notice the same problem with the sigma and tamron (both canon mount, also used with metabones IV), but I suppose that the huge depth of field of the wide lenses played its role here.
The question is if this is a common "behavior" of canon mount lenses and whether I should focus on more contrasty areas (than I used to do with my old canon bodies) or my lens front focuses and needs to be replaced (I still have a 7-day window for replacement). However optically it is almost perfect, so if there is no need, I wouldn't take the risk to get another, maybe optically faulty copy.
Does anybody have such an experience with this lens? Shall I keep it and wait for the next firmware updates by metabones? I have 0.45 firmware installed right now. I would appreciate it if you wrote your experience.
Just thought I would chime in as I have a couple of odd lenses and now have a new sony a7r mk2.
canon ef 50mm F1.0L - focuses very slowly- but does actually focus automatically (didn't with the original a7r).
canon 200mm f1.8L - focuses fast but hunts a little.
I have to say the sony a7r locks focus far more accurately than my canon 5dsr (i have just been spending a few days with them shooting side by side). The canon is generally a fair bit faster at focus but the the sony/metabones is more accurate. This is when shooting with predominantly very wide apertures.

Minas,
I have been using my Canon 24-70mm f/2.8 Mark II on the A7r II with Metabones IV since Metabones updated the firmware to make the PDAF of that camera to be compatible. At that time, the firmware was Version .43. It has worked and it is working beautifully with that lens. In addition to being fast, it is very accurate. I did a session last weekend and I took over 200 images with that combo using the face detection AF and every single frame is perfectly in focus. And it was so easy to do. I am very pleased. Although newer firmwares have been released by Metabones, the latest one is Version .45, I haven't felt the need to update it yet. All my existing Canon lenses work fine with that firmware.
I am not sure whether it is your setting on the camera or it is more a firmware issue you are experiencing. Please check the firmware version by going to the "tool box" folder (far right) and subfolder "version". You will see the version of the camera and the version of your lens (or Metabones, if your adapter is mounted. Since you are experiencing some kind of AF issues, I would suggest for you to look into upgrading to Version .45.
I should chime in here for documentation . The new Tamron 35 1.8 SP works in .43,.44 and it does work in .45 it is faster AF but there is a slight issue when turning camera off than back on the aperture ring sticks to reopen. Fix is twist lens slightly off past contact point of metabones than to back on and it pops open. Sounds like a hassle but only with turning camera on with lens on. When on it functions perfectly and AF did get faster.
Canon 135 f2 in .45 actually did pick up AF speed and also no overblown exposures. I say if you have this lens update and try it. If not go back to .44 . I have all these versions stored away if anyone needs to go back.

Thank you for your response. I have the latest firmware for both the camera and metabones. After doing more testing I realised that the field curvature issue is more prominent than I thought. Especially between 35-55mm, and focusing near infinity the borders are not sharp even at f/8. And as you can imagine, field curvature combined with front focus is a real disaster for the borders. I shoot mostly landscape, so most of my photos are affected by this situation. Does your lens also behave like this?
After all, I think that I need to try a second copy.

Mine is not doing that. None of the curvature of field issue whatsoever. I am so pleased with its performance and now, I am in the process of selling my also great Sony FE 24-70mm f/4 Vario Sonnar since I really like the faster aperture of the Canon and now with IBIS, it is even better. Even during my Canon days, that lens was a superb performer.
It sounds like yours is out of whack . Several years ago, I had a Canon 16-35mm f/2.8 Mk II that suffered from that issue. More recently, my first copy of the Sony FE 16-35mm f/4 was out of calibration like that. Sony ended up replacing that lens with a brand new one and the second copy is an awesome performer. Is your lens still under warranty? Can you send it in to Canon in Greece for them to evaluate it? Yes, it would be a good idea to try another copy in the meantime.

I bought the lens 10 days ago. I live currently in the UK and I have a 21-day window to return it. This is what I will do, after reading about your experience. I have read that the predecessor had severe field curvature issues, which are still there but milder in the new model. However what I have seen in my photos looks totally unacceptable. And the 42mp sensor unfortunately needs a perfect lens.

Nice to read about increase in focus speed. Is this the case for telephoto lenses, which suffered from hunting and lack of accuracy in their tele- end?

I think that's a camera limitation, not an adapter issue.
Even Sony's own A-series telephoto zooms perform very poorly with the Sony LA-EA3 adapter - anything over about 200mm and/or f4 seems to be beyond the camera's AF ability.
! I prefer this lens over the EF 85mm f/1.8.
