1st -- He says that you need a Metabones IV adapter with the latest firmware to use Canon lenses with IS on the A7RII. This does not match my tests:
I have a Metabones III adapter with v30 firmware.
When I put the 70-200mm f4 IS Canon lens on the A7RII I get the following behavior:
- If both lens IS and camera IBIS are on I get overcompensation
- If I turn lens IS on (switch on lens) and camera IBIS off, it works great
- If I turn lens IS off (switch on lens) and camera IBIS on, it works great
2nd -- He says the 135mm f2L won't AF well with the Metabones adapter but will with the Vitrox adapter. So I bought a Vitrox which just arrived and the 135mm f2L doesn't AF with it either.

I am wondering if these 3rd party adapters have variance with contacts to lens or camera? Seems there has been a number of reports of the same brand working or not.

From my experience, if a lens does not AF well. (hunting, bad low light performance), it does not matter which adapter you use and I've tried quite a few. It's just not reliable for most practical photography. Some will be better than others but I would not recommend using certain Canon lenses on the new Sony body.
I have tested the Metabones III and IV with a lot of lenses on the A7RII and the results are pretty much the same. I would not be hopeful a firmware upgrade for either body or adapter will make lenses in the "bad" list somehow start working well...
Also, as I wrote in a previous thread, if you are used to shooting with a Canon body, even the lenses in the "good" list won't give you similar AF performance.

While there is variance from adapter to adapter with making electronic contact, that's not the issue here with my Vitrox & 135mm f2L. When an adapter fails to make contact, the lens doesn't try to AF - it just acts like a MF lens. The 135mm f2L, on the other hand, tries and tries to achieve focus and never does.

I never assumed the Canon lenses would to work as fast as on a Canon DSLR, but how about the accuracy, Fred? That is way more important (to me).

Hey,
So yesterday I received my Sony a7rii and my metabones (mark iv, v0.41) and I've tried it with a couple of lenses that were on the tested list, and so far I get the image on the screen/viewfinder but I have no control over the lens whatsoever.
If I press the c3 button it tells me that's the lens may not be connected properly etc (not sure of the exact wording of error message in English as I live in Japan and have the Japanese version, so error message is in Japanese.)
Just wondered if I'm missing something like I was supposed to activate something in the camera menu etc, for now I can live without auto focus but not being able to control the iris renders the lenses useless.
Lenses I tried were the 24-105, the 135, and the 85. My business partner also received one at the same time and his is acting the same way. Even if they lenses aren't compatible for auto focus is there anyway to control the iris on them?
Thanks in advance

Exact thing happened to me. The metabones is suppose to control the iris when you install it. I have another metabones adapter and it is just plug and play. I deem my metabones mk4 T defective and its going back monday to the store.
My commlite one arrived Saturday for my event today and AF performed pretty well on my 24-105L. I spent an hour testing it on my lenses and I'm not endorsing it because mine fails to AF on my 50L, 85L, and 135L. But it AF on all my zooms, 16-35L 2.8 mk2, 24-105L, 24-70L mk2, 70-200L 2.8 mk2.
UPDATE: I went back to the store and swapped out my Metabones IV T Adapter. It works now, easy plug and play. I tested a few lenses and my 50L, 85L AF now work properly. I have to find some time to test the rest of the lenses.

I'd say, if it locks fast, it's accurate. For those coming from the Sony A7R, the difference is that it uses a ‘traditional’ (slower) contrast detect AF set-up with 25 points. It's slow but accurate as long as there is enough light. In low light it hunts a lot. (Think Canon 5D Mark II live view AF)
The new A7RII has "on-sensor" phase-detection AF that work with adapters. Its phase detect AF points are accurate because they are on-sensor instead of on a dedicated PDAF module, meaning there is no need to micro-adjust our lenses with the A7RII. Future models should improve this even further until a point where they will match SLR performance.
As Fred has mentioned, Metabones has not updated their FW that would cover the A7RII, since the last FW was .41 and that was in June. I am hoping they can get the adapter to work better.
I have found that when my lenses lock on with the adapter, the IV with .41, that the focus is correct.
It works with my 11-24L but oddly, when I go to 24mm it hunts more, As soon as I go wider, it works fine all the way to 11mm. This is more or less like the 100-400II, which works up to 300mm but past that not so much and not well enough that I would use this lens on the A7RII. I hope again, that Metabones can address this.

Thanks for your fast reply, Fred.
Yeah, I'm aware that the on-sensor PDAF should be accurate by design - at least in theory - so it is nice to know that it also works accurate in practice too. Hopefully I will get an a7rII next week to try it out myself.
Drove all the way home in one trip for 12hrs. Tested with 70-200 f4L, result = Bad! Sometimes tries to focus, sometimes does nothing. And when it focuses, it doesn't focus well. Tested with sigma 35 1.4 art and can confirm that it focuses well and fast. All with MB IV B version. Now i need to charge batteries and myself. I'm totalled! /EOF

Every has different needs and some of your priorities of lightening fast AF is not a priority for others. So far the AF of the A7R2 with lenses like the Canon 24-70 or 70-200...prime event lenses, seems pretty good...good enough for me to rent the body and try out for myself. I shoot a lot of manual focus lenses and I must say the DSLR cameras are a big compromise shooting manual focus. Everyone has differing needs. The weight of the A7R with a Zuiko 24mm is ultralight...great for street shooting.
As far as dishing out $3200 for a camera with rebel like AF...don't forget one of the best selling DSLR's was the 5d2 which had mediocre AF...yet was used for all sorts of photography. ...Show more →
Sure. It's my personal take I'm expressing and I fully accept others might be fine with the price and what the camera offers. I'm renting one too and maybe I change my mind. I sure do hate the slowness of the original A7R and was expecting to replace it until I heard the price for the II.
And I never did buy the Canon 5D II...went straight from the 5D to the III.

I can confirm that the 70-200 f/4L IS version works well.

I never said IS. So you have a new lens to add to your list. Btw, did you read my question regarding the 500mm? Anyways, will try myself tomorrow.
For the multitude of owners of the 200L f2, outside, as fast as my 5DIII. Inside hit and miss with vertical lines working but not always on other stuff. But again, outside, fast from infinity to up close and it locks on very well.
After reading all of this, I think the IQ would need to be way better than the a7r for me to upgrade. For $3000 I'd rather add the 5Ds as it will AF great with my lenses and I can use it for wildlife. I then have the a7r for when I need great DR.
With that said, I think the IQ is going to be a pretty big upgrade.

Ok, for fun I put an extension tube on the 24-70II. A 20mm tubes. I was outside, too much breeze so I held a sunflower stock with one hand, so it wouldn't go back and forth, shot with the other hand and the lens auto focussed fast, locked on, got IS, and a sharp image. I couldn't' believe it. So with the 24-70II, inside or out and with extension tubes, it works great!
