Get beautiful, softly blurred backgrounds thanks to the circular aperture of the large maximum aperture of this lens. A linear motor used for focus drive contributes to low-noise focus operation, while a stepping motor built into the lens - technology inherited from Sonys professional camcorders - results in smooth, quiet aperture actuation ideal for recording movies.
