From wide angle to telephoto, this new zoom lens can capture a wide range of subjects. As there is no need to change lenses, there is no risk of missing those great shots. This lens has a minimum focusing distance of 50cm (19.6in.) at all focal lengths and a maximum magnification of 1:5.3. A distance scale on the focus ring makes the lens convenient and easy to use."
