You can now use Canon EF and EF-S lenses on Sony E-Mount full-frame or APS-C cameras with the Metabones Canon EF to Sony E Mount Smart Adapter Mark V. Its 32-bit processor allows a number of vital features such as phase-detect and contrast-detect AF systems support. Electronic Manual Focusing is also supported. This adapter also allows aperture control from the camera itself. The electronic contacts provide distance information that is the backbone for smooth iris effects and image stabilisation. This Metabones lens adapter also has a programmable function button and an LED light for status notifications. Meanwhile, it can also transit EXIF data to the camera to display zoom and distance details on the camera. Auto magnification is also enabled while automatic conversion to APS-C mode is available on selected lenses. With a black interior coating that prevents reflections, a rubber gasket also protects the camera mount against moisture and dust. An Arca-type tripod foot with 1/4"-20 thread on its base can provide additional support for larger and heavier lenses.
Product Features in Detail
Fit Canon Lenses on Sony E-mount Camera Bodies
Gain more versatility by unlocking more creative modes and options when you use this adapter to connect Canon EF and EF-S lenses with Sony E-Mount cameras.
Electronic Contacts and 32-bit processor
The processor and the contacts allow the sending of metadata and the saving of EXIF data. It also makes image stabilisation, aperture control from camera, autofocus, and auto exposure possible.
Supports Phase-Detect and Contrast-Detect Auto Focus
Any Sony-E mount camera will provide contrast-detection autofocus with this adapter. Meanwhile, phase-detection AF is possible with the following Sony cameras: A6300, A6500, A7II, and A7RII.
Use In-Body and Lens Optical Image Stabilisation
This Metabones adapter has an image stabilisation switch that can enable in-body IS for the A7II, A7RII, and the A7SII cameras. It also supports optical image stabilisation with newer lenses. Having IS in both camera body and lens can solidly provide highly-stable images.
Focus Hold Button and LED Status Light
The focus hold button allows you to save up to 50 functions that combine your most-accessed settings and features. Meanwhile, there's no second guessing of the adapter's status thanks to the built-in LED light.
Smooth Iris Support
Perfect for video shooting, the adapter makes the Smooth Iris feature available for fine aperture settings changes. This feature is available for select Tamron, Sigma, and Canon lenses.
Tough, Lightweight Build
Both the camera side and the lens side of the adapter are made of brass to make it durable for repeated usage. It is also precision-machined and plated with chromium to repel wear and tear.
