Used Metabones T Smart Adapter Mark IV for Canon EF or Canon EF-S Mount Lens to Sony E-Mount Camera

Electronic aperture, EXIF, image stabilization, autofocus

This Smart Adapter 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.
• Flocking material coating inside the inner hole to reduce the internal reflection.

Enhancement on new MARK IV (MB_EF-E-BT4) vs. old MARK IV (MB_EF-E-BM4):
• The inner hole is painted with flocking material coating. This can further reduce the internal reflection.

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 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 they 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.

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, they instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of their 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. Metabones 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 m
