Sony 100mm f/2.8 Macro SAL-100M28
(From Sony lens literature) Get incredibly close to small subjects with the Sony SAL-100M28 macro lens. Its superb clarity gives you professional results in almost any shooting situation.
The superb macro-focus lens for both close-up and distant subjects. This versatile macro-focus lens covers a wide range of photographic applications, from close-up nature subjects to midrange telephoto shots -- making it ideal to carry on location or in the field. Mounted on the Sony a (alpha) DSLR-A100 camera, it provides a 150mm focal length (35mm equivalent) -- and its superb sharpness and clarity give you professional results in every shooting situation.
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 f/2.8 Aperture: In conjunction with the Super SteadyShot image stabilization system of the Sony a (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.
