Sony 50mm f2.8 Macro Lens SAL50M28 is 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 an APS format DSLR, this lens provides a 75mm focal length (35mm equivalent) -- which means it can also be used as a standard and midrange telephoto lens.
