Why I opted against the Sony a7xii (it's all about Metabones)

Thanks, but it was definitely (or it was supposed to be...) a BT-IV. And I would not be happy with a new camera that would not allow me to use the bells and whistles with my lenses. I think I will learn to be happy with my situation, and just wait for the perfect camera to come along. Hopefully that will happen at Photokina...
I'm quite satisfied with how my Canon lenses work on a MB IV T + A7RII. But then I also rarely take pictures of bells & whistles... ;)
Show us some BIF images with your Canon 400 F5.6. :-)
I didn't realize that BIF was the only thing a 400mm lens is good for... 😯

Anyway, it would be perfectly capable of doing that as well, unless one expects technology to do all the thinking & work.
Thought the same :)

I drove down to Dunedin today, all set to buy a Sony Alpha a7ii with Metabones adaptor for Canon EF lenses. The camera appeared to be great--excellent size, fit my (relatively small) hands well, nice features, etc etc--and with a Sony E lens attached it focused quickly, and was nice and handy. But when I attached the Metabones IV adaptor (which we discerned had the latest firmware) my EF lenses were extremely slow to focus, almost to the point of being completely unusable. Since my EF lenses are slightly old, we tried some of their brand-new lenses just to see if it made a difference, and if anything it was actually worse. While I was willing to put up with somewhat slower performance than I can get with my Canon 5DmkII, I was not willing to go quite this far, so I ended up leaving with my money still in my pocket.

I think I am now in the position of waiting for Canon to come out with a comparable product, and a way to use my existing lenses. In the meantime, I will bring my Canon body and lenses with me to South America next month, together with my brand-new Sony RX100m3 (which I love so far).
The camera FW was probably not up to date.
 
I thought of that, too, and according to what we could see on the camera, it had the latest firmware. Also, I tried several focus settings on the camera, some were not available for my lenses, and others resulted in very slow focusing.
What you are describing is not normal for PDAF. Obviously the camera was either on CDAF or the FW was not upgraded.

I have an A7II and when I bought it the FW was not updated, I mounted the MB4 and the AF was awful, just as you describe.

Update the FW and it focused at native speed basically.

Matter of fact is fast enough that I photographed BIF the other day with the Tamron 70-300mm F4-5.6.

Either the FW was not correct or somebody had screwed around with the AF settings and it was locked onto CDAF.

Try it again...
 
I just rang the (very helpful and patient) shop that I visited yesterday, and sure enough, the firmware was v2.10 (current firmware is now 3.20!). So, it's back to Dunedin tomorrow (was heading there anyway for a friend's birthday) to check it out. Watch this space...

After reading all these posts I phoned the shop to confirm the FW, and indeed it was WAAAY out of date. So they're updating it today and I'm heading down again tomorrow to check it out.
 
Also make sure Metabones Firmware is .....


I get good results with my Canon 100-400 MkII and the A7RII. Although not up to my Canon 7D II and that lens. But then I did not expect that.
 
A lot of people reported that the adapter does not work with 100-400mm II. It works for you? If so, how much slower comparing to using on a Canon body?
 
It is slow but doable for landscapes and slow moving subjects. Sometimes needs a manual pre-focus. Action, no but then that's why I have my 7DII.

Thanks; the Metabones was v1.49, if I remember correctly (it was the current version, in any event).

That's it.

When I tried mine new out of the box on the old FW, it was a real dog.

You will be blown away by the new FW focus speed in comparison.
 
I sure hope so. I really liked the camera and its functionality, and would really love to have it on my trip next month!
 
What Canon lenses you adapted?

With the latest firmware on my A7 II and Metabones IV-T adapter, my EF 24-70L/2.8 II and EF 35/2.0 IS AF on A7 II very fast. My EF 70-200L/2.8 IS II AF is slightly slower but still fast. As a matter of fact, 24-70L II thru IV-T AF on A7 II is almost as fast as on my 5D2.

I tried it out with the following (all Canon):

16-35mm f/2.8L II

24-70mm f/2.8L (version I)

15mm f/2.8 fisheye

50mm f/1.4

70-200 f/4L II (this was the store's lens, so not sure about whether it was f/4 or f/2.8; it has IS though)
 
It is slow but doable for landscapes and slow moving subjects. Sometimes needs a manual pre-focus. Action, no but then that's why I have my 7DII.
 
When you do check it out, could you be sure to try using a focus point away from the centre setting and see if that works for you/

As I've mentioned, mine focuses quite well if I use the central point but, if I move it off to one of the other points it really struggles. I'd like to know if this is a universal problem or something I am doing, or setting, incorrectly with mine.

Will do my best! How do you select the focus point in the camera? Is it fairly obvious?

You don't know how to change focus point and you wrote off the camera already?

You may not live that long staying with Canon.
 
I do know how to deal with focus points in the Sony universe, and succeeded in changing the selection a few different ways while checking it out, but none of them yielded a positive result. The question that the respondent asked me was not just to change the focus style, but also the focus point, which is something I did not do, and did not know how to do. But even so, if the several different ways that I did try were not yielding a positive result, I did not think that things boded well for the camera with my lenses. Sue me if you like, but I do not spend several thousands of dollars all that readily without being quite sure about it.
