Ultra-Bright f1.4 Aperture - In conjunction with the Super SteadyShot image stabilization system of the Sony (alpha) DSLR-A100 camera, this lens captures bright, steady images even working with hand-held camera in very low light.
Glass-Molded Aspherical Lens - Improves optical stability and precision in creating sharper, more visually accurate images with minimal distortion even at fully open aperture.
Focus Hold Button - For full creative control, a focus hold button located on the lens can lock auto-focusing.
Auto Clutch - In auto-focus mode, the manual focus ring does not rotate -- which improves handling ease.
