Electronic aperture, EXIF, image stabilization, autofocus Your PayPal receipt is your order confirmation. There is no separate email confirmation until shipment takes place. This Smart AdapterTM 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.

Description Compatibility Supported Not supported EF lenses (see below for list of tested lenses) EF-S lenses (see note 1) Image stabilization (IS) lens Electronic manual focusing (e.g. EF L II and discontinued EF L) 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 3) Auto magnify (see note 2) Contax N mount lenses modified to Canon EF by Conurus Contax 645 NAM-1 adapter modified to Canon EF by Conurus Sigma, Tamron and Tokina lenses in Canon EF mount (see note 3) 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) Lens: Tamron SP mm F/2.8 XR Di II VC 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. Requires lenses supporting distance information. 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. 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.

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. 2. Mount lens on EF Extender 1.4x or 2x first before attaching both on Metabones Smart Adapter. 3. 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 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. 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. 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. Our Smart AdapterTM series adapters have the following additional 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. EXIF data such as lens identification, focal length and aperture.
