Lens Adapter Meike for Canon EF/EF-S to Sony E with Autofocus AF (MK-EFTE-B)

The Meike Lens Adapter for Canon EF/EF-S to Sony E with Autofocus AF (MK-EFTE-B) enables the use of Canon EF and EF-S lenses on Sony E-mount mirrorless cameras while maintaining electronic control for aperture and autofocus where supported. This adapter provides mechanical alignment and electronic communication between lens and camera body, allowing photographers to repurpose existing Canon glass on Sony systems for portrait, event and everyday shooting. The compact metal construction is designed for reliable mounting and repeatable fit across compatible lenses and bodies.

Advantages

The adapter retains electronic contacts to transmit aperture information and AF signals between Canon EF/EF-S lenses and Sony E-mount cameras, helping to preserve functionality such as aperture control and autofocus on supported lens-camera combinations. Its mechanical mount ensures secure attachment and accurate flange distance, which supports focus accuracy and image consistency. The adapter is a practical solution for hybrid shooters who want to integrate Canon lenses into a Sony workflow without major modifications.

Suitable for

• Photographers who own Canon EF or EF-S lenses and want to use them on Sony E-mount mirrorless cameras
• Portrait, event and documentary photographers reusing existing glass
• Hybrid shooters combining DSLR lenses with mirrorless bodies for specific focal lengths or optical characteristics

Key specifications

• Mount type: Canon EF/EF-S to Sony E-mount adapter
• Compatibility: Canon EF and EF-S lenses to Sony E-mount cameras (check lens-camera compatibility for AF support)
• Electronic contacts: present to enable aperture control and autofocus communication on supported pairings
• Material: metal construction for mount stability and durability
• Function: mechanical coupling plus electronic transmission for aperture and AF where supported

How to use

Align the red or white indexing marks on the adapter with the corresponding mark on the lens, then rotate the lens until it locks into the adapter. Attach the adapter-lens assembly to the Sony E-mount camera body by aligning the mount index and turning until secure. Power on the camera and confirm contact communication; set the camera to an appropriate shooting mode that supports electronic aperture and autofocus. Test focus and aperture control with the specific lens to verify AF functionality, as performance depends on lens and camera firmware compatibility.

Usage recommendations

Ensure both lens and camera firmware are up to date for best compatibility. When autofocus performance is critical, perform practical tests with the intended lens and subject distance; some lenses may focus more reliably in single-point or contrast-detect AF modes. Use manual focus assist tools in the camera if AF is limited, and avoid forcing mounts—always align and lock parts gently to prevent damage.
