With a range of impressive Canon design features and a compact, lightweight structure, the EF 28mm f/1.8 USM is an extremely portable and easy to handle wide angle lens. If you're looking for a fast f/1.8 aperture with a 28mm wide-angle focal length, this well built, superbly designed camera lens could be for you. One of the features you may find most useful is the USM autofocus. Virtually silent and remarkably fast, the USM AF allows you to focus quickly and accurately, so you can capture the moment each and every time. If you're looking for a bit more control, enable the lens' convenient Full Time Manual focusing feature. You will also notice that this lens features internal focusing, which is ideal if you plan to use filters and accessories, as the front element never moves. What is this lens great for? Wide angles make excellent landscape lenses, however, this handy little lens works well in many different settings.
