Sony SAL50M28

* 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) 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.
