Clearance Alpa Lens to Sony NEX Camera Speed Booster Lens Accessories

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
