Nothing matches the presence and clarity of a wide-aperture lens that's designed for a single focal length. Lenses that meet this description are called "fast primes," because they gather lots of light and they aren't zoom lenses. The optical pathway is less complex than on a zoom lens, and so the images are often breathtakingly sharp. This lens sees the world in much the same way as the eye does, when placed on a full-frame camera. Its 50mm focal length and compact size makes it an excellent choice for travel photography, indoor events, and all-around picture taking. The large maximum f/1.4 aperture lets in plenty of light, allowing faster shutter speeds to "freeze" moving subjects. It also makes it perfect for shooting indoors when the lights are low.
