Metabones MB-EF-E-BTS Canon EF to Emount T Cine Adaptor
New positive-lock EF lens mount.
Store EXIF data (lens name, focal length and maximum/minimum aperture) for up to 2 manual lenses in the adapter.
AF-C tracking during high speed drive at up to 10fps on Sony A9.
If both your lens supports optical image stabilization (OIS) and your camera supports sensor-shift, in-body image stabilization (IBIS), the choice is yours on which one to use, or have both of them work in harmony.
Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lenses.
Custom function button (called Focus Hold button) assignable to more than 50 functions, such as Aperture Preview and Eye-AF, on A9, A7 series, A6500 and A6300.
Dedicated switch controls in-body image stabilization (IBIS) on Sony cameras eqipped with SteadyShot INSIDE.
Sony E-mount teleconverter support.
Compatible with Sony FS7 Mark II camera.
Cinema EOS lens (CN-E) support, including power zoom, AF and auto iris.
Rubber gasket protects E-mount connection from dust and moisture.
Detachable tripod foot, compatible with Arca Swiss, Markins and Photo Clam ball heads.
AF-C is supported on A9, A7 Series, A6500 and A6300 only, and only in Green mode.
Continuous video AF is functional in Advanced mode, but performance may be unsatisfactory.
On Sony A9, only phase-detection autofocus is supported. Contrast-detection autofocus does not work. See firmware release notes for details.
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.
Sony E-mount 1.4x TC (model SEL14TC) will fit and work but AF performance may be unsatisfactory and there may be significant vignetting with some telephoto lenses.
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. Typical problems of this kind that we have seen include an un smooth/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.
