Metabones MB_EF-E-BM3 Overview

  • 1Description

The black Canon EF Lens to Sony NEX Camera Lens Mount Adapter III from Metabones attaches a Canon EF lens to a Sony NEX camera. It is referred to as a "Smart Adapter" because it retains electronic communication between the camera and lens and therefore provides automatic aperture control, EXIF data, image stabilization and autofocus. The adapter is powered by the camera body, no external power source is required.

The Smart Adapter III offers two distinct operation modes: Green and Advanced modes. Each mode supports a different set of features and is selected when you mount the lens. Green mode is the default mode and it is designed to conserve battery power by limiting aperture diaphragm movements and image stabilization. Certain other functions are not available in Green Mode including Auto-Magnify MF Assist and Wide-Open Button.

The adapter's tripod foot is detachable and compatible with Arca Swiss, Markins, Photo Clam ball heads.  

Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus speed is very slow and inadequate for most moving subjects. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus. This Smart Adapter is also compatible with fully manual lenses which have no electrical contacts. For a list of reported compatibility with specific lenses please see the Metabones website.

 

True electronic integration of aperture diaphragm; lets camera automatically choose aperture in Program or Shutter Priority exposure modes, or set it manually on the camera body in Aperture Priority or Manual modes.
The adapter is powered by the camera body, no external power source is required.
Two distinct operational modes are supported by the Smart Adapter III: Green mode and Advanced mode. Green mode limits certain features and disables others in order to conserve the camera's battery power.
Wide-Open button enables aperture to remain open for clear manual focusing.
Auto-Magnify/AF Assist enlarges the image in the viewfinder for easier manual focusing. This feature requires the AF/MF switch of the Canon EF mount lens to be set to the MF position and also requires a Canon EF mount lens that supports distance information. Auto-Magnify/AF Assist is disabled in Green mode.
The tripod foot is detachable and compatible with Arca Swiss, Markins, and Photo Clam ball heads.
High performance 32-bit processor and efficient switched-mode power supply.
Compatible with EF-S lenses, however vignetting at corners may occur for certain EF-S lenses because they are designed to cover a 1.6x crop image circle and Sony NEX has a 1.5x crop sensor.
Compatible with Sony NEX full frame cameras such as the A7 and A7R. The Mark III adapter supports auto "APS-C Size Capture" with EF-S lenses as well.
Supports distance and zoom display on VG and FS series camcorders and auto magnify on lenses that support distance information
Compatible with select fully manual lenses which have no electrical contacts.
Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
Satin surface finish matches lens and camera mounts.
A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus.

    Metabones MB_EF-E-BM3 Reviews

    Canon EF Lens to Sony NEX Camera Lens Mount Adapter III (Black) is rated 4.1 out of 5 by 46.
    Rated 4 out of 5 by from Canon lenses with Sony A7r a greet Combo This metabones adapter allows me to use the Canon lenses I own with the new full frame Sony A7r. Considering the limited Sony Lenses currently available and the good IQ of Canon lenses I can have a wide choices of glasses to use. The adapter has good electrical connections for aperture, autofocus and IS functions. note- initially the adapter was very tight for the 17-40 mm L lens and the 100-400 mm L lens, no issues with 24-105, 70-200 F2.8, 85 and 50 mm. I sent an email and B&H offered to replace the unit, while Metabones Hong kong offered to send a new plate, which I received within three days. With the new plate I installed myself, all the lenses now are fitted well.

    Rated 5 out of 5 by from Life saver fot the SONY A7R This adapter was a LIFESAVER for my new SONY A7R. The service of B&H was great!!! Even that the product appeared in wait to shipping, it arrived at the store 2 days after i ordered it and then arrived here in Mxico City ON DECEMBER 24!!!!! Amazing!, Christmas eve an it WAS here!. I am switching from Canon to Sony because i like the mirror less approach of SONY to the digital cameras. And with the FF sensor!!!!!, wow!!!. I am using my 70-200 2.8 white canon lens, the macro 180mm canon lens and, as you can see in the photos, a SIGMA wide angle lens. Both of the 3 lenses are WORKING perfectly with the adapter. I also used the normal 50mm black and cheap a canon lens with this product. Be aware! auto focus does not work! in some lenses at all, with the white lens it is SO SLOW that it is unusable!. I expected that and is not problem for me because i mostly photograph not moving subjects. BUT WHAT IT WORKS WITH THIS ADAPTER AND ALL LENSES IS THE FOCUS MAGNIFIER helpful to fine tune the focus on this fantastic small camera. I wanted this camera for this feature, and even with this adapter, this great and helpful thing work!!! I am delighted!!!! As this camera comes WITH NO LENS AT ALL!!!!! you can imagine wat a great thing this was to us. The camera came a few days later in December by the way. This was not a gift, i even have to pay about 30% of the value in mexican taxes, but it is worthwhile because of the speed and availability of the B&H store. :)

    Rated 5 out of 5 by from Awesome I have a decent collection of Canon lenses, but love the handling of the NEX-6 (won't replace my 5DMII!!!) for certain things. This device fills the gap providing an almost seamless use of my EOS lenses on the NEX. The image stabilization and setting exposure works, however the autofocus is so-so (certain lenses can hunt) -- however I do not blame this product, but the difficulty in combining these two systems. Mostly I use manual exposure and manual focusing (doesn't everyone? If not, why not?) so the iffy behavior with automatic focusing is a non-issue for me. To be clear, it works, but won't perform well for moving subjects or under low lighting -- you may have better or worse results depending on the lens. And in fairness, the manufacturer discloses this issue. The biggest drawback is that you can see for yourself how much better the Canon lenses are than the Sony E-Mount lenses -- even the 35mm prime is noticeably inferior to its Canon counterpart. The dream here has come true for me: great lenses that I love on a camera that provides focus peaking (almost like using rangefinder, but better) and live exposure histograms (manual made easy).

    Rated 5 out of 5 by from So far so good I purchased this adapter to use with Sony A7. Works great with 18-55 IS STM lens. AF and MF Works excellent (with the use of peaking). AF in low light is faster than the kit lens (28-70). The only thing that is not working as I expected is that in auto crop mode, the camera still uses a crop lens in full frame mode and I have to force the camera to crop with a Canon crop lens and then back to auto mode with my other lens. This is not a big issue though as this is a one time setting when replacing the lens. I would recommend buying this adapter, as it widen the options for a Sony A7/A7r owners. David

    Rated 3 out of 5 by from Works 100% with selected lenses. I have only 5 Canon EF lenses to try with. None of them was compatible. My Canon EF-S 55-250mm works in relation to focusing and stabilizing. However, as expected, vignetting is prominent when fitted to my Sony a7. Somewhere in the internet I've read Metabones document where they listed brands models that fully or partly works with the adapter. In fairness to Metabones I do not have the lens that works 100% with it.I bought the Adapter mainly as a cosmetic upgrade to my a7. Besides, I prefer manual focusing for video and photography of which the Metabones Adapter III (Black) works very well.

    Rated 5 out of 5 by from I like it. Just attach to the Sony A7 and hey presto it works, as long as you use a suitable Canon lens. I use MF so it works on all mine however I did try the 50mm f1.4 on AF and AF didn't work, no problem with the 40mm f2.8 pancake or the 16-35 L. Will try the other lenses when I get back to Scotland although I do not want a heavy lens on this camera. The adapter feels good quality and I have confidence it will last for years, for me it is a no brainer to purchase if you have decent Canon glass and a Sony A7 or A7r.

    This adapter will work fine with my NEX 7 + Di II VC PZD AF Lens for Canon ??I want full range zoom in my nex7 without loss the autofocus, aperture control and Image stabilization.What you recomend for my nex 7?
    Asked by: Anonymous
    This adapter will not work with your Tamron AF18-270 lens, as it is EF-S type, and this adapter is designed for Canon EF mount. For an adapter that will allow you to use electronic functions on your EF-S type lenses on an NEX-7 look at the Dot Line Lens Mount Adapter for Canon EF/EF-S to NEX: http://bhpho.to/1c2UAYJ

    question

    Does this adapter support full frame on the Sony A7? Is there a crop factor?
    Asked by: Anonymous
    There would be a crop factor if a Canon EF-S lens is used on the adapter. It the lens is for full frame use, like the EF series, then it will remain at it's proper focal length.

    question

    How to choose Green or Advanced function? Are those functions available in camera menu? Firmware upgrade is made through camera? At what extent are auto-focus velocity is compromised by this adapter? At green mode how much of the auto-focus and stabilization are compromised?
    Asked by: Anonymous
    The Green mode is used by default on the Metabones Canon EF Lens to Sony NEX Camera Lens Mount Adapter III. You select the operation mode when you mount the lens. To check the adapter firmware version of your adapter, attach any Canon EF lens to the adapter and put it on a Sony NEX camera body. Press the 'MENU' button and choose the 'Setup' icon. Find the 'Version' function in the list. Metabones Smart Adapter firmware upgrade is a factory service procedure. No user-installable update is available. Please ship your Smart Adapter to Metabones if you require a firmware upgrade. Autofocus speed is very slow and inadequate for most moving subjects. For both Green and advanced modes, the autofocus speed is unfit for professional use for sure, and it would disappoint most enthusiasts, and additionally, continuous autofocus is not supported. Image Stabilization is supported.
