Metabones MB_EF-E-BT6 (MB EF E BT6, MB EF-E-BT6, MB/EF-E-BT6, mb_ef-e-bt6) Canon EF Lens to Sony E Mount T CINE Smart Adapter
Features and benefits:
Fast contrast-detect AF on all E-mount cameras.
Phase-detect autofocus support on A7RII, A7II, A6300 and A6500.
Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lenses
Supports 5-axis in-body image stabilization of A7II, A7RII and A7SII. (Distance information from lens required; 3-axis IBIS if lens does not transmit distance information.)
Powered by camera body. No external power source required.
Aperture control from camera body.
Custom function button assignable to more than 50 functions on A7 series, A6300 and A6500.
Dedicated IBIS (in-body image stabilization) switch for A6500, A7II, A7RII and A7SII.
LED indicator shows operation mode, OIS (optical image stabilization) activity and communication status.
High performance 32-bit processor and efficient switched-mode power supply.
Supports image stabilization (IS) lenses.
Supports electronic manual focusing (e.g. EF 85/1.2L II and discontinued EF 50/1.0L)
EXIF support (focal length, aperture, zoom range)
Distance and zoom display on VG and FS series camcorders, A7 series, A6300 and A6500 (lens with distance information support required).
Auto magnify (lens with distance information support required)
Auto "APS-C Size Capture" on full-frame cameras with Canon EF-S lenses and many third party DX lenses.
Fits both EF and EF-S lenses. (Vignetting at corners may occur with certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony APS-C has a 1.5x crop factor.)
Flocking material coated inside the opening to reduce internal reflection.
The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo Clam ball heads
Continuous AF and video AF are not supported. (Performance may be unsatisfactory.)
AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8.
The first two autofocus attempts are used to calibrate the lens and as a result may not lock successfully on the target. Half-press the shutter release button again and autofocus will lock successfully.
Autofocus may have difficultly locking onto subjects which are very close to the nearest focusing distance of the lens.
Autofocus accuracy depends heavily on the design and working condition of the lens. Lenses with hidden problems which may not be apparent on Canon DSLRs will lead to inaccurate and unreliable autofocus on Sony NEX. Typical problems of this kind that we have seen include an unsmooth/erratic autofocus mechanism (e.g. getting stuck intermittently at a certain focusing distance), a faulty/worn-out distance encoder or other faulty/worn-out internal sensors.
No support for lens corrections such as peripheral shading, CA and distortion.
The EF-mount lens may make audible noises during iris changes and autofocus, wich may be picked up by the built-in microphone of the camera during video recording. Use of an external microphone is advised.
Early Tamron VC lenses such as the AF 28-300/3.5-6.3 XR Di VC LD Aspherical [IF] Macro (model A20), AF 18-270/3.5-6.3 Di II VC LD Aspherical [IF] MACRO (model B003), SP AF 17-50mm F/2.8 XR Di II VC LD Aspherical [IF] (model B005) may not be able to freely switch between OIS and IBIS because they may not report IS activity status. Later Tamron VC lenses equipped with USD or PZD focus motors are fine.
Some aftermarket battery grips may cause the aperture to change erraneously. This is a bug of the aftermarket battery grip but NOT arising from the Metabones Smart Adapter. Turn off the aftermarket battery grip or use a genuine Sony battery grip.
Tested Camera Bodies:
Fast AF on all E-mount cameras:
Tested by the community on A7RII for fast phase-detect AF:
Phase-detect AF on A6300, A6500, A7II and A7RII only, unable to contrast-detect AF accurately if at all
Manual focus only
Focus confirmation "chip" (e.g. Dandelion)
Tamron 28-300/3.5-6.3 XR Di VC LD Aspherical [IF] MACRO A20 (note 1)
* with smooth iris support
Note 1: Unstable due to unusually high current requirement.
