Lens correction such as peripheral shading, CA and distortion Focus confirmation "chip" (e.g. Dandelion) Stacking another lens mount adapter on top (see note 4) NEX-VG900

Note:

1. Vignetting at corners may occur for certain EF-S lenses because they are designed to cover a 1.6x crop image circle but Sony NEX has a 1.5x crop sensor.
2. Image Stabilization lens?requires adapter firmware version 02 or above.
3. Requires lenses supporting distance information.
4. 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.
5. For example, some improperly-made M42 screw mount adapters may cause a short-circuit with the electronic contacts of the Smart Adapter??and cause damage to the Smart Adapter??and/or camera body.?

Manual Focus Only

The following lenses have been tested with previous firmware versions with manual focus, aperture control, image stabilization (if applicable) and EXIF support. Autofocus is supported only for those lenses marked with an asterisk (*), on NEX-5R/6, and with adapter firmware version 18 or above.

• Samyang 35/1.4
• Zeiss CP.2 25mm/T2.9
• Zeiss CP.2 100mm/T2.1

Note:

1. 1. Lenses not listed above are not tested and they may or may not work. We do our best to resolve any compatibility issue you find but firmware updates are by factory service only and there is a nominal shipping/handling charge of $50.
   2. Mount lens on EF Extender 1.4x or 2x first before attaching both on Metabones Smart Adapter.
   3. Some samples of Sigma lenses may require adapter firmware Version 12 or above to function properly.
   4. Mount Contax 645 lens on modified NAM-1 first before attaching both on Metabones Smart Adapter.

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 III and 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. If you have a lower version and require an update, please send your Smart Adapter back to us. There is a nominal shipping/handling charge.
