Metabones Canon EF Lens to Sony NEX Smart Adaptor (Mark III)

Metabones Canon EF Lens to Sony NEX Smart Adaptor (Mark III)

For the underwater photographer, the Metabones adaptor can be used to shoot the Canon 60mm f/2.8 Macro lens on your Sony NEX camera. The Nauticam Macro Port and Gear Set for Canon 60mm f/2.8 Macro includes the lens gear for manual focus.

This Smart Adaptor has the following features:

• 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.
• Powered by camera body. No external power source required.
• Wide open button (opposite of depth-of-field preview function) makes manual focusing easy.
• The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo cam ball heads.
• High performance 32-bit processor and efficient switched-mode power supply.

Notes:

• 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.
• Requires lenses supporting distance information.
• A third party zoom lens may need to be registered with the Smart Adaptor first in order to detect its maximum aperture.
• Autofocus is disabled for most third-party lenses.

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; it would disappoint most enthusiasts
• Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be 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.
