Outlet Alpa Lens to Sony NEX Camera Speed Booster (Open Box) Lens Accessories

*Item pictured for illustrative purposes only, actual item not pictured.

The Metabones Alpa Lens to Sony NEX Camera Speed Booster allows  a full frame Alpa lens to be mounted to an NEX APS-C format camera and  in doing so, increases the angle of view and increases the maximum  aperture one f/stop. The lens follows this tradition of uncompromising  precision, robust build quality and outstanding finish. It uses  matte-black treatment to keep internal reflection to a minimum in order  to maintain the maximum optical quality possible with the lens. 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.

Features:

• Allows a full frame Alpa lens to be mounted to an NEX APS-C format  camera and in doing so, increases the angle of view and increases the  maximum aperture one f/stop.
• Both the camera-side and the lens-side of the speed booster are made of brass which is precision-machined and chrome-plated.
• Precise fit and solid connection – lens has no play, gap or wiggling  when mounted on speed booster and no adjustments are required to fit  your lens.
• The Speed Booster uses matte-black treatment to keep internal  reflection to a minimum in order to maintain the maximum optical quality  possible with the lens.
• This Metabones Speed Booster has two different operation modes,  Green and Advanced. In Green Mode battery power is conserved by reducing  certain functions. For example, in Green Mode there is no depth of  field preview and no auto magnify manual focus assist. The operation  mode is set when you mount the lens.
• The lens’ aperture is set to wide open for ease of focusing while  the Wide-Open (WO) button of the Metabones Speed Booster is depressed.  Release the button and the lens will return to the aperture set on the  camera. This wide-open function is automatically shut off when you  actually take a picture and during movie capture.
• This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
• Although the lens will fit physically, automatic diaphragm (AE  metering), or other auto functions are not retained using this speed  booster.
• Satin surface finish
