Compatibility

Supported Not supported

EF lenses

Image stabilization (IS)

Electronic manual focusing (e.g. EF 85/1.2L II and discontinued EF 50/1.0L)

EXIF (focal length, aperture, zoom range)

P, A, S, M exposure modes

Autofocus (see autofocus support section below)

Distance and zoom display on VG and FS series camcorders (see note 1)

Auto magnify (see note 1)

Contax N mount lenses modified to Canon EF by Conurus (see note 2)

Contax 645 NAM-1 adapter modified to Canon EF by Conurus (see note 2)

Sigma, Tamron and Tokina lenses in Canon EF mount (see note 3) 

EF-S lenses

NEX-VG900 (see note 4)

Lens correction such as peripheral shading, CA and distortion

Focus confirmation "chip" (e.g. Dandelion)

M42 screw mount adapters (see note 6)

Stacking non-Metabones/non-Conurus mount adapters on top (see note 7)

Super-telephoto lenses (see note 8)

Note:

  1. Requires lenses supporting distance information.
  2. Autofocus disabled for Contax N and Contax 645 lenses.
  3. A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
  4. This Speed Booster™ is designed to cover an APS-C image circle which is not big enough to cover a full-size 36mm x 24mm sensor.
  5. Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with the Speed Booster™, the resulting aperture is f/0.9 but the camera body displays f/1.0.
  6. Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster™ and cause damage to the Speed Booster™ and/or camera body.
  7. Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed Booster™. They need to be modified before they can be safely used on Speed Booster™. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed Booster™ are not covered by warranty.
  8. Super-telephoto lenses such as the Leica-R Telyt 560/5.6 may have significant vignetting in the corners.

Autofocus

Autofocus is supported, with the following known limitations.

  • Autofocus speed is very slow and inadequate for most moving subjects. The autofocus speed is unfit for professional use for sure, and it would disappoint most enthusiasts.
  • Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus is disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus.
  • On NEX camera bodies in camcorder form factor (e.g. FS series), autofocus may be available only in photo mode but not in movie capture mode.
  • Continuous AF is not supported.
  • DMF mode (direct manual focus) is not supported.
  • For non-camcorder camera bodies (e.g. NEX-7), during movie capture, if the subject moves to a different distance, half-press the shutter release button to re-activate autofocus and lock onto the subject again. Since autofocus speed is slow, there may be visible disruption in the resulting footage.
  • The first two autofocus attempts are used to calibrate the lens and as a result may not lock successfully on the target. Half-press the shutter release button again and autofocus will lock successfully.
  • Autofocus may have difficultly locking onto subjects which are very close to the nearest focusing distance of the lens.
  • Autofocus accuracy depends heavily on the working condition of the lens. Lenses with hidden problems which may not be apparent on Canon DSLRs will lead to inaccurate and unreliable autofocus on Sony NEX. Typical problems of this kind that we have seen include an unsmooth/erratic autofocus mechanism (e.g. getting stuck intermittently at a certain focusing distance), a faulty/worn-out distance encoder or other faulty/worn-out internal sensors.
  • Autofocus is supported only on Mark II Smart Adapters but does not work on the older Mark I version.
  • Firmware version 14 or above is required. There is no firmware download but firmware update is a factory service procedure. Firmware version 14 is our first attempt at autofocus and we anticipate further improvements and bug fixes in future versions. Therefore, we advise existing Mark II Smart Adapter customers to wait for our next firmware release before sending in your adapter for firmware update. If you should require an update right away, please email Metabones and send your Smart Adapter back for a firmware update. There is a nominal shipping/handling charge of $50.

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.

Metabones Canon EF lens to Sony NEX Speed Booster follows this tradition of uncompromising precision, robust build quality and outstanding finish.

Features

  • 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.
