Bought this to use with my new A7r and my collection of Canon L glass. Works great, very professional design with a tight fit on the body. Wide angles like the Canon EF 16-35mm f/2.8L II worked great with full aperture control from the body. Focusing is a tad slow like using live view on a Canon body, the native Zeiss 35mm f/2.8 is noticeably faster. Only small thing so far was the Canon 85mm f/1.2L II registers as having f/1.3 as it's widest aperture available but it still focused with the body just fine. Very happy with this purchase given the small native Sony lens selection at the A7R's launch. A must buy item as far as I'm concerned if you have any other glass from another camera manufacturer and are just jumping into the Sony world with the A7-series like I am.

This is an impressive (and complex) piece of gear. I'd give it five stars, except for two problems:

1) Slow automatic focusing , minus one star.

A lens, like the Canon 24-105mm f/4 zoom or the Tamron 24-70mm f2.8 zoom, that achieves quick focus when mounted on a Canon body, will hunt from near to far before it achieves focus when mounted on a Sony body via this adapter. This problem, common to other adapters of this type, seems irresolvable, except maybe with a more powerful computer in the adapter and/or a smarter translation algorithm. This slow focusing isn't a problem with most of my shooting, but I wouldn't use this adapter to shoot my grandkids' soccer games.

2) Sometimes, no automatic focusing at all, minus another star.

I believe this problem, which occurs sometimes with some lenses, is due to mounting the adapter to the camera without first turning the camera on, so the adapter and camera can do a little electronic handshake, as stated in the Metabones Adapter Manual. Of course, the problem with doing this is that if you change lenses with the camera on, the sensor attracts dust like crazy, so the way to do this is to mount the adaptor and lens with the camera off, turn the camera on, and partly remove the lens, rotating it just enough to break the electronic contacts but not enough to let dust in. It's a pain, but when your lens stops focusing, this seems to help.

Yes, there is a manual, and you should read it before using the adapter. The manual isn't supplied with the adapter, and there isn't even a little note in the box the adapter comes in telling you where to find the manual on the web. You should Google "Metabones Adapter Manual" and print it out.

The Metabones 3 adapter is solidly built of steel with a decent weight to it, so construction wise it should last quite a while. It comes in a very nice foam padded box giving the adapter plenty of protection from knocks.

This is currently the only Full Frame Canon EF to Sony E mount adapter that I'm aware of. It also supports Canon EF-S lenses if you have any APS-C lenses lying around.

Full EXIF information is relayed from your lens to the camera and it works well with most Canon EF type lenses. I've tried 4 Canon lenses and the only one that doesn't autofocus is the 50mm f1.8 lens, all others work fine. In this respect my Commlite adapter works better although that is only an APS-C adapter and not full frame like this one.

Autofocus does take a bit longer than using the lens on a native Canon body and sometimes there can be quite a bit of hunting going on, although this is more the exception than the rule. Autofocus, whilst not fast is perfectly adequate for most shots.

The Metabones adapter fits very snugly onto the Sony A7 and the lenses attach very snugly and lock into place into the adapter.
It is recommended that you attach the lens first to the adapter, turn the camera on then fit the lens/adapter combo onto the camera body. Whilst this is the recommended approach, I don't like turning the camera on without a lens attached so tend to skip that part and it still works well.

You get full control over the lens in PASM mode and aperture works fine. There is a button on the side of the adapter which gives you "Wide open" mode, although to be honest I've not had the need to use this.

I love the Metabones, I have shot a trailer for a feature on one and it behaved so well I purchased my own. Allows control of Aperture via Sony FS100 Iris scroll wheel and indicates the Fstop via the on screen display. The adapteer fits snuggly to the camera body and the lens when attached is solid.

The only issue I have ran into is since the adapter is powered by the FS100, it messes with bootup (if my FS100 is off and I try to turn it on, it wont boot on) and also sometimes the aperture loses functionality, I have fixed this by disconnecting the adapter and reconnecting it, solving the issues. To me it's a tiny issue I can easily love with. Also if you have a stabilized lens, the stabilization works as well.

Love this.
