Manufacturer's Description:
If you shoot with an APS-C format camera and want a lightweight,
compact lens that will handle snapshots and portraits plus macro
photography as well, this is it. The 35mm equivalent focal length of this
lens is a distinctly “normal” 45mm, making it a good choice for general
photography. But when an exquisite little detail catches your eye, you can
move in as close as 2 centimeters from your subject to capture macro
images with up to 1:1 magnification. The details you focus on will be
astonishingly sharp, while the out-of-focus background dissolves into a
creamy blur that can really make the details stand out. The SAL30M28 is
only 45 millimeters long and weighs a discreet 150 grams, so it can stay
on your camera or in your bag at all times without getting in the way
