Key Features

Features and Benefits  

Limitations

Electronic

  • Autofocus
  • Phase-detection autofocus (PDAF) on supported camera bodies*
  • Can be powered either by camera body or by third-party external 5V power source (not included)
  • Iris/aperture controlled by the camera body
  • Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lenses
  • Image stabilization lens support (Canon IS, Sigma OS, Tamron VC)
  • Support for cameras with in-body image stabilization (IBIS)
  • Electronic manual focusing (e.g. EF 85/1.2L II, EF 50/1.8 STM and discontinued EF 50/1.0L)
  • EXIF (focal length, aperture, zoom range)
  • Distance and zoom display (requires lenses supporting distance information)
  • Cinema EOS lens support (CN-E 18-80mm T4.4 L, CN10x25 25-250mm T2.95, etc.), including AF, auto iris and servo zoom (may require external power)
  • LED indicator shows adapter status
  • Support Panasonic Tele-converters (DMW-TC14, DMW-TC20 and DMW-TC20A)

Mechanical

  • The tripod foot is detachable and compatible with Arca Swiss, Markins and Photo Clam ball heads.
  • Flocking to reduce internal reflection.
  • Rubber gasket protects the MFT mount connection from dust and moisture.
  • Compatible with all MFT mount cameras, including G9II, GH7, GH6, GH5, OM-1, OM-D, Blackmagic Cinema Camera, Blackmagic Pocket Cinema Camera and JVC GY-LS300.
  • Supports EF-S lenses.
  
  • AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8.
  • Some older third-party lenses may have unsatisfactory AF accuracy.
  • No support for Focus Stacking and Focus Bracketing on Olympus/OM System.
  • Most 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.
  • Use of Canon Cinema lenses such as CN-E 18-80mm T4.4 L IS KAS S and CN 10x25 25-250mm T2.95 for still photography is not supported. (Functional, but slower than lenses designed for still photography.)
  • Iris changes are 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. This limitation does not apply to Cinema EOS lenses which permit fine resolution iris control, such as CN-E 18-80mm T4.4 L IS KAS S and CN 10x25 25-250mm T2.95.
  • No support for in-camera correction such as peripheral shading, CA and distortion.

* If C-AF and C-AF-TR become greyed out on OM System OM-1, try turning on the "Keystone Correction" option on the camera, and then turn it off.



Description

Why Metabones®?

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.
