SAL-50M28 50mm f/2.8 Macro Lens
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 ? (alpha) DSLR-A100 camera, the SAL-50M28 macro lens provides a 75mm focal length (35mm equivalent), which means it can also be used as a standard and midrange telephoto lens.
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 ± (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.
In auto-focus mode, the manual focus ring does not rotate — which improves handling ease.
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.
