A compact macro-focus lens that covers the full range from life-size to infinity. "Life size" macro imaging means that the image you capture is the same size as the subject in reality - giving you spectacularly sharp photos of insects, flowers, gemstones, postage stamps and other small nature subjects and collectibles.
Features 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 α (alpha) range of cameras, 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.
