SAL-100M28 100mm f/2.8 Macro Specification
SAL-100M28 100mm f/2.8 Macro Lens
The versatile SAL-100M28 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 your Sony (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 f2.8 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.
