Metabones Canon EF Lens to Sony E-Mount T Smart (Mark V) MB-EF-E-BT5
Features and benefits
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.

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.

there may be significant vignetting with some telephoto lenses.
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 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.
Use of Canon Cinema
lenses such as CN-E 18-80mm T4.4 for still photography is not supported.
(Functional, but slower than lenses designed for still photography.)
Some EF-mount lenses
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. Some of the recently-introduced Canon-brand
lenses are very quiet, however.

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.
