The Metabones Canon EF Lens to Sony E Mount T Smart Adapter is designed to allow the mounting of Canon EF mount lenses onto the Sony a7S II and other Sony alpha series DSLR cameras.
The adapter provides aperture control and auto-focus abilities when using EF mounted lenses.

Electronic

• Phase-detect autofocus support on A7RII.
• Supports 5-axis in-body image stabilization of A7II and A7RII,
• Powered by camera body. No external power source required.
• Aperture control from camera body.
• Wide open button (opposite of depth-of-field preview function) makes manual focusing easy and assignable to a custom function on A7 series.
• 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 (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.

Optical/mechanical

• Fits both EF and EF-S lenses. (Vignetting at corners may occur for certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony NEX has a 1.5x crop sensor.)
