Product Details:
Sharp Macro Focusing - You can get closer to your subject to capture low-angle shots of insects, flowers and other natural wonders and broad depth of field lets you keep backgrounds in focus too.
Bright f2.8 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 low light.
High Contrast and Resolution - Excellent optical precision gives your shots greater visual accuracy for close analysis of your subject.
Focus Range Limiter - Speeds auto-focus response by limiting the range of distances that are brought into focus Close-up Range, or Telephoto Range.
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.
Circular Aperture - Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
