SAL-50M28 - 50mm f/2.8 Macro LensSAL-50M28

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. Mounted on the Sony® α (alpha) DSLR-A100 camera, this lens provides a 75mm focal length (35mm equivalent) -- which means it can also be used as a standard and midrange telephoto lens.
Feature List
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.
