Metabones MB_EF-E-BT6 Overview

Bring out your Canon EF and EF-S mount lenses for use on a variety of full-frame and APS-C format Sony E-mount cameras with this Metabones EF to E Mount T CINE Smart Adapter. This cinema-styled electronic adapter features a positive-lock lens mount that will ensure that your adapted lenses are secure. Further improving on previous generations of Smart Adapters, this fifth-generation model now features a rubber gasket to protect the camera's mount from dust and moisture, offers a status notification LED light to check operation modes, and a dedicated switch that controls in-body image stabilization of select cameras. Also, this version is compatible with the Sony PXW-FS7 Mark II video camera.

This adapter is equipped with numerous capabilities thanks to the use of a high-performance 32-bit processor. The features include support for both phase-detect and contrast-detect AF systems as well as the ability to control the aperture from the camera body. Smooth iris effects are possible as well on select lenses and 5-axis stabilization is available thanks to communication of distance information with supported lenses. Also, it features a programmable function button, enables electronic (focus-by-wire) manual focusing, transmits Exif data to the camera, and works with in-lens image stabilization. Additionally, distance and zoom is displayed on certain camcorders and mirrorless cameras, auto magnify can be enabled, and it can automatically switch into APS-C mode depending on the lens used.

Beyond electronic communication, the adapter has many physical advantages as well, such as a black felt flocking on the inside of the adapter that prevents reflections. For larger lenses, there is a removable Arca-type-compatible tripod foot with a 1/4"-20 thread on the base.

Allows users to adapt a Canon EF/EF-S-mount lens to a full-frame or APS-C Sony E-mount camera.
Positive-lock lens mount provides extra security when attaching large lenses.
Electronic contacts permit transmission of data between the lens and camera enabling autofocus, auto exposure, image stabilization, aperture control from the camera body, saving Exif information, and more.
Status notification LED light on the adapter will show the user what mode the adapter is currently in.
Dedicated switch for controlling in-body image stabilization.
Programmable function button for rapid access to commonly used settings and features.
Support for phase-detect AF with the a7R II, a7 II, a6500, and a6300 cameras.
Compatible with Sony PXW-FS7M2 (FS7 Mark II) camera.
Smooth iris support with select Canon (2009 and later), Tamron (SP series 2013 and later), and Sigma (2016 and later) lenses.
Enables electronic manual focusing on lenses, such as the Canon EF 85mm f/1.2L II, that use a focus-by-wire system.
Support for distance and zoom display, auto magnify, and auto APS-C Size Capture settings on select cameras.
Internal felt flocking prevents reflections.
Removable Arca-type compatible tripod foot with 1/4"-20 thread.
Powered by camera body.

DO NOT BUY

By Tahiel

I bought this adapter without doing enough research and it is a horrible concept. Check reviews on Youtube for this product! It basically requires two people to change the lens and sometimes it gets tightly stuck on the lens. Both my 70 - 200mm and 24 -105 mm canon lenses do not fit well into this design. It is not an easy operation as it should be for changing lenses. Now, I'm stuck with this product because I threw away the original packaging.

I've been shooting my Canon lenses on a Sony with the Metabones.� So far its been great with no issues.� I took it out of the box, put it on the camera and got to work.� Some of the machining tolerances can be improved and should be for a the expense of this item, but its a small inconvenience.

Good adapter for video but has some pitfalls

By Andrew N.
Rated 4 out of 5
Date: 2018-03-09

As far as I am aware of, this adapter currently is the only one on the market that provides a positive lock with electronic contacts from Canon EF to Sony E. What this means is that you can get a rock solid connection between the your Canon EF lens to the front of the adapter. So no play whatsoever for doing focus racks.� But on the flip side you must remember that the Sony E mount is spring loaded so from the camera side you will get a bit of play / movement on heavier lenses. (This is true for all adapters) The solution to reduce all play is to lock this adapter to a cage via something like a Metablock from Lock Circle.� Also note that you need to be very careful when you remove / attach your lens as the lens will fall straight out of the adapter when it is fully unlocked. Also note that although this lens provides an electronic connect that works great for video. For photo you don't get fast autofocus. This is more of an adapter that you would use for video with manual focus. Sum up: Great for video work with some considerations to note. But bad for autofocus photography.

Worth It

Think about how much you spent on your lenses, it's worth having a secure adapter to make sure they're safe. It also allows the lens to communicate to your camera (A7 series) to give you more control in camera.

No AF with Canon lenses for video shooting

By Luigi

I spent a fortune to realise that this metabones lens adapter is useless to shoot video if you need autofocus on canon lenses. If you need AF for your video shooting, buy original Sony E-Mount lenses, or probably compatible E-Mount lenses. Adapter I guess are useless.

Love the mount ring! Easy on, easy off.

By Samuel

I know others who hate how tight the mounting ring can get when you mount a lens with this. Honestly, I would have to call that user error. This thing is easy on and easy off, just don't wrench the lens onto the adapter. It is secure.

question

Will this adapter support autofocus in video mode with the Tamron 24-70 f/2.8? How will the autofocus speed compare to the 24-70 G Master on the A7r II?
Asked by: John
The adapter will work but adapting the notably slower Tamron in a different mount to the very recent and native g master lens, there will be a clear difference in video autofocus speed.

I have Schneider Xenon Cine lenses with EF mounts. Would this be the suggested mount for a Sony A7R IV? Thanks.
Asked by: Dennis
You could use this. Keep in mind that a Cinema Lens is a manual lens and there is no electronic communication. You could use a more basic option instead. https://bhpho.to/2RfFwEo

Will this work seamlessly with Sony Fx9 auto focus feature and my canon 24x70/70x200 lenses?
Asked by: Scott
While this will allow you to use EF lenses on a camera like the FX9 auto focus never transitions over smoothly for video with this or any other adapter. The only way to get smooth auto focus is to use native E Mount lenses with the camera.

question

How does the autofocus speed in video mode with this adapter compare with a native lens?
Asked by: John
Native lens will always focus better than an adapted lens. This will also be determined by the Sony body being used. Currently, the best mirrorless camera to adapt are the Sony A7ii, A7rii, A6300 and A6500. I have yet to see an adapter focus in Video modes with the Sony and have not tested this version of Metabones yet.
