Metabones MB_EF-M43-BT2 Overview

The T Smart Adapter for Canon EF or Canon EF-S Mount Lens to Select Micro Four Thirds-Mount Cameras from Metabones allows a Canon EF or EF-S mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter is designed to support electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. If an attached lens is also capable of generating EXIF metadata when used with a directly compatible camera, the T Smart Adapter is designed to allow that information to be saved along with image files generated with a combination of the lens, a Micro Four Thirds-mount camera, and the adapter.

By enabling camera-controlled aperture functions for a Canon EF or Canon EF-S Mount Lens when used with a Micro Four Thirds-mount camera, program, shutter-priority, aperture-priority, as well as manual modes can be set and used through the camera. Power for these functions is transferred from the camera to the lens, and when manual focusing is preferred with a compatible electronic lens and a Panasonic camera, an integrated jog dial that allows incremental aperture adjustment can be depressed to open the lens's aperture diaphragm to its largest setting. The resulting shallow depth-of-field can then be used to help ensure focus accuracy.

When an image is taken with the T Smart Adapter, a matte black internal coating minimizes the potential for reflections within the adapter barrel, which could otherwise result in unwanted glare within the image.

The T Smart Adapter is constructed from aluminum alloy for durability while minimizing weight. Its mounting rings are made with brass to further prevent wear-and-tear, and a detachable tripod foot is included that features 3/8" threads as well as compatibility with Arca-Swiss tripod heads.

While the T Smart Adapter allows a Canon EF or EF-S mount lens to be mounted onto any Micro Four Thirds-mount camera, any functions that involve electronic communication currently require a Panasonic-brand Micro Four Thirds-mount camera.

  • Allows a Canon EF or EF-S mount lens to be used with a Micro Four Thirds-mount camera
  • Allows third-party, full-frame or APS-C EF-mount lenses to be used with a Micro Four Thirds-mount camera
  • Supports electronic communication between camera and lens to enable autofocus, image stabilization, on-camera aperture control, and EXIF metadata generation when possible
  • Internal coating minimizes reflections within the adapter barrel
  • Integrated jog dial for incremental aperture adjustment and push-button access to lens's widest aperture setting when used with a compatible Panasonic camera
  • Detachable, Arca-Swiss compatible tripod foot with 3/8" threads
  • Aluminum-alloy components for weight reduction
  • Brass mounting rings further prevent wear-and-tear
  • Locking mechanism for secure attachment of lens with push-button release

What does that rocker-type switch do? The one to the right of the mount release.
Asked by: Matt
The "rocker type switch", is an integrated jog dial that allows for incremental aperture adjustment, and can be depressed to open the lens's aperture diaphragm to its largest setting. One would use this switch especially when one is not getting electronic communication between camera and mounted lens.

question

Will this work for the tokina 10-17 fisheye attaching to an e-m1? If so will there be any cropping?
Asked by: Michael G.
Yes this Metabones T Smart Adapter will connect a Tokina 10-17mm fisheye lens for Canon onto an Olympus OM-d E-M1 camera, or any other Micro Four Thirds camera mount. There will not be any cropping of the lens from the adapter, but there will be cropping because of the camera's sensor size. You will have to convert the focal lengths properly because it has a 2x crop-factor to account for. You will be getting an effective zoom range of 20-34mm fisheye with this setup.
