Metabones Canon EF Lens to Micro Four Thirds T Smart Adapter [MB_EF-m43-BT2]
Metabones Canon EF Lens to Micro Four Thirds T Smart Adapter
Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters, in order to ensure smooth mounting, great appearance, and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart AdapterTM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
- Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
- Satin surface finish - just like your OEM lens and camera mounts.
- Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
- Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
- True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
- EXIF data such as lens identification, focal length and aperture.
Powered by camera body. No external power source required.
Aperture control from camera body.
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 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.
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 Micro Four Thirds has a 2x crop sensor.
Flocking material coated inside the opening to reduce internal reflection.
The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo cam ball heads.
The inner opening is lined with flocking material coating. This will further reduce internal reflection when a tilt-shift (TS) lens is used.
No video AF for Olympus
AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8.
AFC (continuous AF) and AFF (flexible AF) modes are not supported
Panasonic video AF may hunt more than a native lens or have unsatisfactory performance.
Tamron lenses may have unsatisfactory video AF accuracy. Canon and Sigma lenses are fine. No support for Focus Stacking and Focus Bracketing on Olympus.
On Olympus, other than E-M1, you may move the single AF point among any of the 81, but you may not multi-point AF. There is no restriction on E-M1 and Panasonic.
EF-mount lenses are not silent but may make audible click noises during autofocus operation and iris changes which may be picked up by the built-in microphone of the camera. An external microphone is recommended for video.
Iris changes are unsmooth but in 1/8 stop steps which may be noticeable in video recordings. Programmed exposure mode and shutter priority exposure mode should not be used for video.
No support for in-camera correction such as peripheral shading, CA and distortion.
- Compatible With All MFT Mount Cameras
- Powered by camera body
- Aperture control from camera body
- Supports image stabilization (IS) lenses
